AUDI fuel consumption Activator — a device which is installed on a fuel hose of any Audi car and significantly reduces fuel consumption Audi by 20% and improves the engine performance.
Therefore, with the same amount of fuel on your Audi, you will drive MORE KILOMETERS!
Activators on AUDI fully pay off in 3-4 months!
The service life of Activators for AUDI is 10-15 years.
Activators are installed on all models of Audi and are used in all types of fuel — GAS, PETROL, DIESEL FUEL.
The activators are easy to install, they are installed on the Audi fuel supply hose in a few minutes:
1. Audi fuel consumption is reduced by 20%.
2. A slight increase in the power of the Audi engine.
3. Extends the service life of the Audi engine.
4. The content of carbon monoxide and other pollutants in Audi exhaust gases is reduced by 30-40%.
5. Stable and dynamic operation of the Audi engine.
6. Reduces the formation of soot and carbon deposits on Audi pistons, cylinders, spark plugs, fuel injectors, catalyst and exhaust pipes.
7. Extends the service life of the Audi catalyst, lambda probe, spark plugs and Audi fuel injectors.
AUDI ACTIVATOR reduces fuel consumption by 20% of any Audi model.
At the same time, the engine operation of Audi is significantly improved.
Examples of installation on different models of Audi.
ANY FUEL (petrol, diesel, gas), by going through 10 magnetic fields of THESE ACTIVATORS, for a short time changes its structure and properties, and it BURNS more fully and REGULARLY.
Due to this, the Audi engine begins to work much BETTER.
Usually, it is already seen after 10-20 km of run of the car Audi which has an installed Activator.
Imagine, how your AUDI engine works with VERY GOOD FUEL …
That is, we have quite different (better) fuel.
You agree that chopped firewood burns much better than whole logs … The same thing happens with automotive fuel in the cylinders of the Audi engine.
Activators installed on Audi reduce the density and viscosity of fuel:
1. This leads to the formation of smaller fuel particles, ensures good atomization and combustion in the cylinders of the Audi engine.
2. The fuel ignites better and burns smoothly, ensuring soft and smokeless operation of the Audi engine.
3. Reduces deposits on injectors and carbon deposits on candles and Audi cylinders.
4. Reduces the load on the operation of Audi fuel supply systems.
5. Increases reliability and increases the life of Audi fuel equipment.
All this leads to improved conditions for fuel combustion in Audi cylinders.
FUEL with Activators burns more completely in the Audi engine, does not leave carbon deposits on pistons, cylinders and spark plugs.
On Audi cars, the injectors are not polluted, and there is no black smoke even at throttling at free running.
Knowing where the fuel hoses are located, Activators at Audi are installed within 5 minutes (see «INSTALLATION»)
ATTENTION! The main difference of THESE ACTIVATORS is that there are 20 magnets placed in them, which for a short time CHANGE THE STRUCTURE AND PROPERTIES OF FUEL. In other similar Aktivators which can be used on Audi, there are only 2 powerful magnets which are not able to change anything in the fuel (see «ANALOGUES» ).
When you don’t like the Aktivators, then with no doubt you can return them back within 37 days (read «RETURN»).
ACTIVATOR reduces the fuel consumption of any AUDI vehicle by 20%. Therefore, with the same amount of fuel on your Audi, you will drive MORE KILOMETERS!
The operating life is at least 15 years
We produce and sell them starting from 2008

Why has Audi’s fuel consumption increased?
This issue often worries motorists. In this article, we will look at the main reasons why Audi’s fuel consumption may increase.
1, Engine problems affect Audi’s fuel consumption
Let’s start with the worst case scenario, which is engine problems. Externally, the engine may be fine, but some components involved in the combustion cycle may be faulty. For example, a faulty spark plug and oxygen sensor in a gasoline engine or a dirty fuel injector in a diesel engine can lead to higher fuel consumption of the Audi.
2. Improper engine oil increases Audi’s fuel consumption
One of the reasons why Audi consumes more fuel may be because of unsuitable engine oil. This is an important element necessary for proper engine operation. You should be careful when choosing engine oil. A viscous oil, compared to the recommended one, will cause the engine pistons to move less freely, causing overheating and increased fuel consumption of the Audi.
3. Low fuel quality increases Audi’s fuel consumption
Low-quality fuel seriously affects the operation and service life of the engine. There are many different additives available at gas stations that improve engine performance. But be careful when choosing additives. Improper additive can be harmful. A good fuel additive cleans the intake valves of Audi gasoline engines and injectors of Audi diesel engines to reduce the accumulation of deposits after fuel combustion. In this way, the increased fuel consumption of Audi can be avoided.
4. Frequent use of the air conditioner and Audi fuel consumption
Using an air conditioner is one of the reasons why Audi consumes more fuel. The air conditioner wastes energy from the engine, and the engine is put under more stress, consuming more fuel. If you do not close the windows at a tolerable temperature, this can reduce Audi’s fuel consumption. However, if you are driving at high speed, then opening the windows increases the drag, forcing the engine to run harder. When driving at high speed, the car air conditioner will not consume much Audi fuel.
5. Worn tires increase Audi’s fuel consumption
If your car’s tires are worn out, traction is lost. This is one of the reasons why Audi can consume more fuel. If the tires are inflated below the recommended pressure, the car will also use more fuel. Regular tire maintenance is a good habit that will help you avoid running out of fuel on an Audi.
6. Late maintenance and short trips affect Audi’s fuel consumption
Late maintenance leads to an increase in Audi fuel consumption. If you ignore your car’s maintenance intervals, you’re probably using up more fuel. The elements of the air system are clogging up, and more fuel will be needed. If you often travel by car for short distances, you will also notice that a lot of fuel is consumed. This is due to the fact that trips of less than 5 km do not allow the engine to reach the optimal operating temperature, so Audi’s fuel consumption increases.
7. Driving in the wrong gear and Audi fuel consumption
For car owners with a manual transmission, driving in low gears consumes more Audi fuel. Driving in high gears will also lead to more fuel consumption. To achieve efficient engine operation, we recommend selecting the optimal transmission in advance.
8. Unnecessary idling increases Audi’s fuel consumption
You can save more Audi fuel by turning off the engine when stopping for a long time. For example, you can turn off the engine at a traffic light if you need to stand for more than 1 minute. For your information, it takes less fuel to restart the engine than to run it at idle.
9. Audi’s worn-out clutch and fuel consumption
When the clutch is worn out, the discs slip instead of rotating each other. This will lead to a loss of the total power that the wheels receive from the engine, reducing the efficiency of the transmission and increasing the fuel consumption of the Audi.
10. Overloading increases Audi’s fuel consumption
Take a look at the vehicle’s operating manual to find out how much cargo it can carry. The recommended load limit that the vehicle can carry is checked by the manufacturer. Overloading can affect not only Audi’s fuel consumption, but also the suspension, tires, transmission and engine. Cars with roof-mounted luggage racks also have high fuel consumption, as roof racks affect the airflow while the car is moving.
So, these were the factors that influence the increase in Audi fuel consumption. Some of them can be eliminated by yourself, but some require serious attention from specialists. Be sure to keep an eye on your car and the increase in Audi fuel consumption at an early stage so that you can easily deal with this problem.
Fuel consumption Audi 1.9 TDI
Over the past 20 years, this engine has been recognized as the best diesel engine produced from 1991 to 2010. It was installed on the following models:
Audi A3 I — 09.1996-05.2003;
Audi A3 II — 05.2003-05.2010;
Audi A3 Sportback — 09.2004-05.2010;
Audi 80 B4 — 09.1991-12.1994;
Audi A4 B5 — 01.1995-11.2000;
Audi A4 B6 — 11.2000-12.2004;
Audi A4 B7 — 11.2004-06.2008;
Audi A6 C4 — 06.1994-10.1997;
Audi A6 C5 — 04.1997-01.2005.
It is a workhorse that consumes a minimum of fuel and has an increased resource. Over the course of its history, more than 10 modifications of the legendary engine have been released, which differ from each other not only in coding, but also in the type of turbine, the power system, and the alloy used for the cylinder heads and block. The engine power, depending on the version, is 90, 110, 115, 130, 150 HP.
Unlike gasoline, diesel has never been quiet. To reduce vibration during operation, the motor was equipped with cushion supports for the engine compartment, but it was not possible to achieve perfect noise insulation. In terms of operational problems, the 1.9 is considered the most reliable motor. The first flaws in his work can be noticed already after 300 thousand mileage. There will be rapid oil combustion and increased exhaust emissions during gassing. Among the serious problems that may arise with the engine are the replacement of the camshaft, the repair of air flow sensors and the restoration of wells for injectors, and for units manufactured after 2002, the replacement of pump injectors.
Fuel consumption Audi 2.0 TDI
A dynamic and economical engine developed back in 2007, but the way we know this engine today, it became in 2015, receiving the serial number EA288. It has the same cylinder block as the 1.9, a similar gas distribution mechanism. The main difference is the Common Rail injection system, in which fuel is supplied to the injectors from the fuel ramp. It is thanks to this system that it was possible to reduce fuel consumption, noise level and exhaust gas toxicity.
Despite the effectiveness of the 2.0 engine, it has a number of drawbacks. The first generation had a factory defect in the oil pump shaft drive, although this problem was detected no earlier than 200 thousand kilometers. It was easy to solve it by replacing this part. The second problem is the failure of the DPF filters. It is also common to see tooth breakage on the plastic tension wheel near the throttle flaps. It is not uncommon for owners of cars with this engine to deal with the problem of turbocharger failure, which leads to oil in the intake system.
Fuel consumption Audi 3.0 TDI
Modern models use the 3.0TDI engine, which first appeared on the Audi A4 B7 in 2004. Today it can be found on A4 B8, A5 and A5 Sportback, A6 C6 and C7, A7 and A8 II-III, Q5 and Q7 cars. This is a six-cylinder model with a cylinder diameter of 83.0 mm and a piston stroke of 91.4 mm. The compression ratio is 17.0. The motor is characterized by good wear. In Russian reality, it easily passes 170 thousand km, after which it is necessary to more carefully monitor the heart of the car, especially its chain drive. As with all VAG diesels, this engine has an intake manifold defect. In this case, the part changes completely, as the flaps are combined with the electronic part. But these disadvantages are offset by the almost perfect traction of the engine.
It is very difficult to answer the question of which Audi engines are the most reliable, because gasoline and diesel are fundamentally different and perform different tasks. Both new and time–tested engines behave perfectly even when leaving the warranty resource, so even buying a used car is not an indicator of the voluntary acquisition of problems. To avoid breakdowns, it is necessary to take into account the recommendations for maintenance from the manufacturer and service the machines only in certified centers.
Audi what is the fuel consumption
People who buy prestigious cars also think about fuel consumption, as do most owners of mid-range cars. And it’s not just the increase in fuel prices, but also the rise in insurance prices. Modern Audis are equipped with turbo engines, which are considered much more economical than atmospheric engines. Is this true and which Audi engine consumes the least fuel and at the same time provides good traction and acceleration?
Fuel consumption Audi petrol engines
Audi’s arsenal includes TFSI gasoline engines powered by direct fuel injection technology. Through the nozzle openings, the fuel is efficiently distributed through the combustion chamber, does not lose its uniform structure, and thus retains its properties. This allows you to save on refueling and provides excellent acceleration dynamics. Since 2014, TFSI engines have acquired new indexes related to power.
Fuel consumption Audi 35 TFSI
The minimum that can be seen on modern Audis is a 35 TFSI engine with a volume of 1395 cm3. At the moment, they are equipped with both sedans and crossovers with front-wheel drive. This motor has a power of 150 hp and produces a torque of 250/1500–3500 Nm/rpm. At the same time, consumption, as well as speed, depends on the overall size and weight of the car.
The new Audi Q3 has been powered by a 35 TFSI engine since 2018, but with a volume of 1,495 cm3 instead of 1,395 cm3. At the same time, its main parameters did not increase and remained in the range of 150 hp and 250/1500 – 3500 Nm/rpm. It gives a maximum speed of 211 km / h, accelerates to hundreds in 9.6 seconds, and fuel consumption at manual transmission – 7.7/5.4/6.3 (city/highway/mixed). It is recommended to fill the Audi Q3 exclusively with AI-95.
What is the actual fuel consumption of the 35 TFSI? According to Audi A3 Sedan owners, the car consumes about 7.5 liters in the city, while the A3 Sportback’s gasoline consumption is 9 liters in the city and 6.5 liters on the highway. A4 consumes approximately 8.5 liters in the city and 7 liters outside the city.
Fuel consumption Audi 40 TFSI
This engine is installed on both front-wheel drive and all-wheel drive vehicles, and this is another determining consumption factor. With a volume of 1984 cm3, it produces power and torque of 190 hp and 320/1500-4200 Nm/rpm.
The actual consumption with this engine is also higher. For example, the A3 Sedan quattro, running on AI-98 gasoline, consumes about 9.5 liters in the city, the A4 Sedan gets just over 6 liters on the highway and about 10 in the city.
Fuel consumption Audi 45 TFSI
Starting with the Audi A4, cars are equipped with a 1984 cm3 engine with a capacity of 249 hp and a torque of 370/1600-4,500 Nm/rpm. The consumption of this engine depends on the vehicle configuration and its weight. The minimum fuel requirements are AI–95 gasoline, but this engine is not averse to trying AI-98.
With the 45 TFSI engine, the second generation of the Audi Q3 crossover is also being produced, only for this car they have developed their own engine. Its consumption is much higher than that of the rest of the Audi 45 TFSI, and this is due to its lower power. Under the hood of the 2018 Q3 is 230 hp, producing 350/1500-4400 Nm/rpm of torque. Gasoline consumption in the city/highway/mixed mode is 9.7/6.4/7.6 liters per 100 km, respectively. The manufacturer recommends filling the Audi Q3 with gasoline no lower than AI-95, but even in this case, its actual consumption will be slightly higher. According to the owners, this car consumes about 11 liters in the city. Sedans running on 45 TFSI are also not ideal. For example, the A4 Sedan quattro consumes all 8 liters instead of the 5.9 liters it was supposed to use in mixed mode. Today it seems like a lot, but until recently, the progenitor of the modern Audi 80 four had a combined fuel consumption of 9.4 liters with a two-liter engine only according to the passport.
The 45 TFSI of the Q7 stands apart. Its power is 252 hp with a torque of 370/1600–4500 Nm/rpm. This engine gives a maximum of 233 km/h and accelerates to 100 km/h in 6.9 seconds. Petrol consumption – 8.9/6.5/7.4 liters.
Fuel consumption Audi 55 TFSI
The heart of Audi’s business sedans. This motor gives the car excellent dynamics and traction. Its volume is 2,995 cm3, its power is 340 hp, and its torque is 500/1370 – 4,500 Nm/rpm. When buying a business class car, you need to be prepared for the fact that its gasoline consumption will be quite high. To save money, the manufacturer lowered the fuel quality level: the 55 TFSI engine runs on the AI-95.
Separately, there is the A6 Allroad and Q7 engine, which has a power of only 333 hp and a torque of 440/2900-5300 Nm/rpm. Its top speed is still the same 250 km/h, the A6 Allroad starts in 5.3 seconds, and the Q7 in 6.1 seconds. The A6 Allroad’s gasoline consumption is – 9.9/6.2/7.6 (city/highway/mixed), at Ku-seventh – 9.4/6.8/7.7 .
Fuel consumption Audi 60 TFSI
It is equipped with an Audi A8 executive class car. The power of this engine is 460 hp, the torque is 660/1800-4500 Nm/rpm. The manufacturer recommends filling the A8 with AI-98 gasoline. The engine provides a top speed of 250 km/h and starts to a hundred in a record 4.4 seconds. The fuel consumption of the new Audi A8 is 13.6–13.8 liters in the city, 7.7-7.9 liters outside the city and 9.9-10.1 liters in the mixed cycle. At the same time, such consumption is close to the truth.
Diesel fuel consumption Audi
Turbocharger units using direct fuel injection technology and having the abbreviation TDI are the brainchild of German developers. It was on the Audi 80 that a diesel engine was used for the first time, although an atmospheric one, which had a power of only 54 hp. Fuel consumption was impressive for those times – 6.7 liters per 100 km. In 1989, the true TDI appeared.
Fuel consumption Audi 35 TDI
Unlike gasoline, the index 35 in diesel is used for engines with a volume of 1968 cm3. Their power is 110 hp, and the torque is 320/1500 – 3250 Nm/rpm. Small but smart: the motor provides the car with excellent dynamics.
And again, the Q3 stands out from the list in the most minimal configuration. With a power of 150 hp, the engine produces a torque of 340/1750-3000 Nm/rpm. It shows a speed of 207 km/h and accelerates from the start in 9.2 seconds. Fuel consumption in this configuration – 5.4/4.5/4.9 l/100 km. (city/highway/mixed).
Fuel consumption Audi 40 TDI
Another two–liter engine with a volume of 1968 cm3, but its power is 190 hp. The torque is 400/1750–3000 Nm/rpm.
The actual consumption depends on the operating conditions of the vehicle. For example, the A5 Sportback in urban mode consumes an average of 8.4 liters per 100 km, which, in general, corresponds to the data stated by the manufacturer. Smooth driving on the same car can even give a consumption of less than 7 liters.
Fuel consumption Audi 45 TDI
The 45 TDI engine is the most powerful diesel engine in the Audi range. It is placed on premium cars. Its volume is 2967 cm3, power is 249 hp, and torque is 600/1500-2750 Nm/rpm. It is paired with the tiptronic automatic.
Fuel consumption Audi RS series cars
The charged S and RS versions received the most powerful engines. They run exclusively on gasoline. The engines have not received new indexes, and only the abbreviation TFSI is used in their classification. These cars are bought for driving, speed and traction are important to their owners. But it’s still interesting to find out what the consumption will be, for example, for the RS4 Avant and RS6 Avant performance, because these are legendary cars originating from the Audi 80 and Audi 100. And just as owners used to monitor consumption, Audi fans are now choosing a powerful and economical car.
Audi TT
This car is imbued with the spirit of sports, it is ready to blow up the air and dissect space. The heart of the small but fast Audi TT is the 2.0 TFSI petrol engines with a volume of 1984 cm3. Available in two versions: 197 hp and 245 hp. Fuel consumption for Audi TT with lower power – 8.1/5.0/6.1 , and with more – 8.5/5.3/6.5 liters per 100 km . With all-wheel drive, the car consumes 9.0/5.9/7.0 in the city/highway/mixed mode.
The actual fuel consumption of Audi cars strongly depends on the model, engine, type of drive, operating conditions (city, highway) and driving style. I will provide some approximate real-world data and sources, as well as examples.
Some real Audi fuel consumption data
General statistics
According to Auto-ABC, the actual consumption of Audi models can be significantly higher than stated: for example, for Audi A4 gasoline — +18%, for A6 — +24%, for Q5 gasoline — +29%.
Audi’s average registered consumption (according to myfuelmanager.com ) ~ 7,724 l/100 km.
Audi A4
According to Drom (modifications of different generations): consumption can vary from ~3.9 to ~14.9 liters/100 km, depending on the engine and conditions.
Judging by the owners’ reviews, in some cases the consumption can be «very high»:
«16.801 L/100 km» on Reddit by a user with A4.
But there are also very economical cases: another owner on Reddit reported 5.4–5.6 liters /100 km when driving evenly along the highway.
Audi A6
According to Drom: for example, an Audi A6 with a 2.0 liter diesel engine (robot, all-wheel drive) consumes about 6.2 liters/100 km.
According to Auto-ABC, the actual consumption may be higher than calculated at the factory for gasoline and diesel versions.
Audi A5
According to Drom: A5 modifications (gasoline) consume ~7.5–7.9 liters/100 km, depending on the version.
There are owners who note the effectiveness of diesel versions.:
«consumption … when driving calmly is 5 liters / 100 km» — one of the commentators about the A5 TDI.
Audi Q5
The stated (licensed) combined figures for the Q5 TFSI are ~7.5–6.5 liters/100 km (depending on the version).
But according to real tests (for example, in Australia) It turned out that the Q5 consumes 17% more than stated — about 5.6 liters / 100 km was noted in one test.
Also in the owners’ discussions: the Q5 2.0 TDI version can «eat» 11-11.5 liters/100 km in the city, and on the highway — ~6.4–6.8 liters/100 km.
Conclusions
Audi’s actual fuel consumption is often higher than the manufacturer’s stated consumption, especially if you drive in the city and aggressively.
Diesel versions (TDI and similar) can be significantly more economical on the highway, but in the city the difference can be leveled.
Management, driving style, load, and technical condition of the car strongly influence: two owners of the same model may have significantly different expenses.
When choosing an Audi, if consumption is important, it is worth looking not only at the factory figures, but also at the real data from the owners.
It is quite difficult to find exactly the «real» (owner’s) consumption data for Audi models for 2023-2025 — a lot depends on the modification (engine, drive) and operating conditions. Nevertheless, below are approximate estimates + real figures from owners and sources that can be used as a guideline.
Current real fuel consumption — popular Audi models (A3, A4, Q5, Q7)
Audi A3 (2023–2025)
According to Drom, for A3 facelift 2024 (sedan, 1.5 TFSI) consumption is approximately 5.5 liters/100 km.
For the A3 Sportback 40 TFSI version (204 hp), the indicator from the technical data is 6.7—7.3 liters/100 km.
A3 owners report variability:
«sometimes about 6 liters/100 km, sometimes up to 8 liters/100 km» — depending on the driving mode and style.
There are reports of popular tests: one user of the 2025 A3 35 TFSI reported an average consumption of 6-7 liters/100 km in the flight log.
Conclusion for A3: in reality, you can expect a flow rate of about 5.5–8 liters / 100 km, depending on the version and conditions.
Audi A4 (2023–2025)
According to Fuelly (owners), the average fuel consumption of the 2023 Audi A4 is ~27.24 mpg (~8.6 l/100 km).
Specifically for the Quattro version, the owner reported a consumption of ~30.8 mpg (~7.6 l/100 km).
According to Car & Driver, in the highway test, the A4 45 (2.0, turbo) showed 33 mpg (~7.1 l/100 km) in their mode.
There is data from CarExpert for the A4 2024 version (diesel): combined consumption — 4.9 liters/100 km.
Conclusion for A4: the actual figures vary greatly, but approximately 7-9 liters / 100 km for gasoline turbo versions and ~ 5 liters / 100 km for diesel (depending on the version).
Audi Q5 (2023–2025)
On Analyst Day 2024, Audi says that the combined consumption of the Q5 can be 5.6–9.1 liters/100 km (depending on the version/engine).
In an independent AAA test (in Australia) for the Q5, it was found that real models consume 17% more gasoline than stated — about 5.6 liters/100 km is indicated in this test.
The owners complained on Reddit: in urban mode, the consumption can be «up to ~ 13 liters/100 km.»
Conclusion for Q5: in reality, we can expect a combined consumption in the range of 6-9 liters /100 km, but in urban operation it is much higher, especially with gasoline turbo engines.
Audi Q7 (2023–2025)
For the Q7 (for example, the 45 TDI version — or similar), Audi technical data (from official specifications) indicate a combined consumption of 8.4–7.8 liters/100 km.
In the owners’ reviews (on Reddit), there are much higher figures for urban traffic: one of the users of the 2020 Q7 complains of «22-23 liters/100 km» for short city trips (however, this may be an «instant» consumption, not an average one).
Also on another long journey in a Q7, one owner reported an average economy of ~26.5 mpg (~9 l/100 km) on the highway.
Conclusion for the Q7: in reality, the average fuel consumption can be about ~ 8-10 liters / 100 km (depending on the version and mode), but in the city it can «jerk» up a lot, especially with frequent accelerations and stops.
General remarks and cautions
The actual consumption data strongly depends on driving style, climate, congestion, type of roads, etc.
Some «expenses from the owners» are based on the readings of the on-board computer, which may not be absolutely accurate.
Official data (WLTP, EPA, etc.) often give more optimistic figures than the real ones.
When choosing a car, it is important to look at the specific modification (engine, drive) — different versions of the same model can consume very differently.
Current (2024-2025) estimates of Audi’s real consumption in Europe
The general deviation of the actual cost from the declared one
According to Auto-ABC (a European resource), Audi’s real fuel consumption is on average ~23% higher than stated for both gasoline and diesel engines.
For specific models: A3 — +27%, Q5 — +29%, Q7 (diesel) — +30%.
This means that the figures in the official technical data may be quite optimistic.
Audi A3 (2024-2025, Europe)
According to Drom: facelifted A3 2024 (sedan) with 1.5 L engine (petrol) — 5.8 l/100 km.
A3 Sportback 40 TFSI version (204 hp) — official technical data gives a consumption of 6.7–7.3 liters/100 km.
The owners note in the discussions that the real average values can be from ~6 to ~8 liters/100 km, depending on the conditions and driving style.
Audi A4 (2024)
Model A4 35 TFSI (150 hp) according to automobile-catalog.com : the average (combined) consumption is 7.9 liters/100 km.
The Drom also has data for A4 diesel and petrol versions. For example, 2.0 L diesel (for the European market) in some versions is about 5.8 l/100 km.
According to Auto-ABC, the real consumption of A4 (gasoline) is about +18% higher than factory consumption.
Audi Q5 (2024)
The official Audi (Germany) program for the Q5 (45 TFSI, MHEV) indicates a combined consumption of 9.1–8.3 liters/100 km.
According to AAA data (European tests may differ directly, but it shows a trend), for some Q5 models, the actual values are higher than stated — in one of the tests they found +17% to the laboratory figures.
The Q5 2024 (3rd generation) Drom has hybrid versions — for example, 2.0 gasoline hybrid: 3.3–3.4 liters/100 km (depending on the version).
Important: These «hybrid» versions listed on the Drom can be light hybrids or mild hybrids, which greatly affects consumption.
Audi Q7 (2024)
According to Drom data for the facelifted Q7 (2nd generation, from 01.2024):
3.0 L diesel engine: 8.4 l/100 km.
Petrol engine 3.0 L hybrid: indicated 11.0 liters/100 km.
According to Auto-ABC, the real deviation of the Q7 (diesel) consumption can be up to +30% relative to the stated one.
Also, users in discussions (Reddit) complain about «zhor» in urban mode — for example:
«I get about 12 mpg (city)» — which corresponds to very high fuel consumption on short and dense routes.
Conclusions and recommendations
Even for the latest models (2024-2025), Audi’s real consumption figures in Europe differ significantly from factory data, especially if average deviations (~+20-30%) are taken into account.
When estimating consumption, it is important to look at the specific modification (model, engines, hybrid/non-hybrid, drive), because the variation is very large.
Data from the owners (forums, flight logs) is useful, but it is subjective and depends on the conditions (city/highway, driving style).
If the expense is critical for you (for example, for the operating budget), it makes sense to focus on the real reviews of the owners in your region + take into account fuel, tariffs, and driving style.
Here is an overview of the most common problems with popular Audi models (A3, A4, Q5), as well as their weaknesses. Of course, a lot depends on the year of manufacture, engine, and mileage, but I’ve gathered the main points worth paying attention to.
Typical problems of popular Audi models
Audi A3
Oil pump drive malfunction
For some 2.0 TDI diesel engines in A3 (especially older models), the oil pump drive wears out, which can lead to a drop in oil pressure.
2. Destruction of fuel pipes (in diesel models)
The fuel tubes may crack due to engine vibrations.
3. Problems with the diverter valve (boost relief valve)
On turbocharged TFSI engines, the diverter valve may “burst”, which leads to boost losses, reduced power, and a characteristic sound.
4. Suspension — squeaks
Owners complain of creaks and noises in the suspension, especially due to the wear of the silent blocks and racks.
5. Corrosion on the wings (“rusty wings»)
Some A3 models have corrosion on the front fenders.
6. Electrics and sensors
Frequent problems with oxygen sensors and the MAF sensor.
Audi A4
(Especially the B8, B9 and TFSI/EA888 models)
Oil consumption
A typical problem with the 2.0 TFSI is that the oil is “eaten up” due to wear on the piston rings or the engine structure.
Carbon accumulation (“carbon build-up»)
Carbon accumulates on the intake valves (at the “direct injection”), which causes ignition failures, unstable operation and a drop in power.
Timing chain tensioner malfunctions
Older EA888 engines (especially the first generations) may have problems with chain tensioners.
Plastic thermostat / water pump
Some engines have a water pump or a thermostatic housing made of plastic, which can cause leaks and overheating.

Pendant
Wear of the silent blocks, especially in the front suspension.
Electronic failures (MMI, sensors)
May be MMI block freezes, problems with ABS/ESP sensors.
Water leaks
In models (for example, B8), water may enter through clogged drainage channels, which can damage electronic modules and carpets.
Audi Q5
Excessive oil consumption
Especially on older Q5s with 2.0-liter turbocharged engines — it is often necessary to top up the oil.
FINN
Timing chain problems
There have been cases of premature chain and tensioner wear in the past, especially on earlier Q5s.
FINN
The start-stop system
Models from around 2017-2020 may have malfunctions in the start-stop system: delays during restart, problems with brakes or power steering.
Problems with the sunroof / roof
There are reports of manhole leaks, clogged drainage hoses — water can get inside and flood electronic components.
Cracks on the fuel pump flanges
Some Q5 fuel pump flanges may have microcracks, resulting in small but dangerous fuel leaks.
Electronics and control modules
Due to water ingress or wear, there may be electrical failures, especially if there are leaks in the cabin.
Maintenance cost
On average, the repair and maintenance of the Q5 can be more expensive than that of simple or “mass-produced” machines.
Common “brand” issues that may apply to different Audi models
Electrical “glitches»: sensors, sensors, multimedia, MMI — are quite common.
Oil/vapor leaks from the PCV system: resonators, PCV valves — may wear out, leading to leaks and contamination of the intake tract.
Suspension wear: The multi—link suspension is good, but expensive to repair.
Oxygen (O2) sensor sensors, MAF: may fail, causing engine control problems.
Owners’ opinions (forums)
One Q5 owner says:
“I loved it … then … the drain from the sunroof was clogged … water … flooded … a … control module … $14,000”
At the same time, another owner of the Q5 (2.0) defends this motor and says that there are no problems.:
“the EA888 Gen3 … is reliable … No engine problems whatsoever.”
Another A4 owner complains about oil consumption:
“it uses 1 ltr of oil every 400 miles … that’s not uncommon … avoid”
Conclusions and advice
When buying a used Audi A3 / A4 / Q5, it is very important to check the engine condition, especially the oil level and service history (whether the rings were changed, whether the intake was cleaned, how the timing chain was maintained).
It is worth paying attention to the drainage channels of the hatch / window, especially in the Q5, to avoid problems with water and electrics.
It’s good if a service station or mechanic is familiar with Audi’s “German” problems — this can save a lot of money and nerves.
When taking a test drive, pay attention to startup noises, vibrations, suspension behavior, and the start-stop system.
