The turbo fuel stratified injection engine is Audi’s most often used engine (TFSI). When gasoline is pressure-injected into the engine’s combustion chamber to provide an immediate charge, this is referred to as the turbo aspect.
The TFSI engines’ direct fuel injection combined with turbo or supercharging technology results in a powerful ride while using up to 15% less gasoline than a V6 engine.
So how does it function? Direct fuel injection improves efficiency and responsiveness by eliminating heat from the intake air, which raises compression and eliminates knock.

Do Audi TFSI engines work well?
Make sure you receive the engine you desire by understanding what the labels on your Audi imply. Naturally, the majority of auto dealers will prominently designate vehicles with their fuel type, but understanding the manufacturer’s own shorthand might be useful nonetheless.
What does TFSI stand for?
Every gasoline-powered Audi vehicle has the TFSI badge, whereas TDI is the emblem for diesel vehicles. The acronym TFSI, which stands for “Turbocharged Fuel Stratified Injection,” designates a turbocharged gasoline engine. Audi used to sell ‘FSI’ engines, which lacked turbochargers, for about 15 to 20 years.
Since the fall of 2017, Audi cars frequently have a number before the TFSI or TDI logo. The power of the car is indicated by these two numerals, which range from 25 to 70. Audi claims that the number is there to make it simpler to compare gasoline or diesel, hybrid, and electric vehicles. It has nothing to do with the size of the engine or the amount of horsepower you get. When ordering a new Audi, you can choose to have the badge removed if you’d like.
TFSI vs TSI
The only brand in the Volkswagen Group to utilize ‘TFSI’ emblems is Audi; the majority of the other brands use ‘TSI’. As engines are frequently transferred between brands without any alterations, there tends to be no distinction between the two in more recent vehicles.
TFSI was utilized on belt-driven engines and TSI on chain-driven engines in some earlier cars, but it doesn’t seem like that’s the case now.
Audi TFSI e engines
An Audi TFSI e engine isn’t just a regular petrol engine despite the small “e” that is added. You’ll notice it if you’re gazing at the Audi Q5 TFSI e or another of the brand’s numerous plug-in hybrid (PHEV) vehicles because it denotes that the vehicle is a PHEV.
In this case, a battery, one or more electric motors, and a gasoline engine are combined. Typically, a fully charged battery will provide at least 30 miles of electric range, improving fuel economy and lowering operating expenses.
Audi TFSI engine problems
The Audi TFSI engine has generally proven to be dependable, but like with all engines, proper and appropriate maintenance is the secret to longevity. Higher-than-average oil consumption in pre-2012 TFSI engines could be unimportant or, in rare situations, a hint that the engine’s piston rings are perhaps worn. Although recirculation valves and injectors appear to be components to watch out for, TFSI and TSI engines are generally known for their dependability.
Which is superior, TDI or TFSI?
A 2.0ltr Q5 S Line Plus in Mythos Black with a black pack and titanium wheels, as well as a few additional extras to make life with it a little nicer, is pretty much what we’ve decided to go with. Our Discovery 3 has been with us for seven years, and we typically retain our cars for at least five years. We would rather buy a car outright than finance it through a PCP or lease.
Which should I choose: the tdi or the tfsi? We travel 6k miles year on average, about 30% of which is within the city and the rest is spent on lengthy trips with the kids and the annual family vacation. Normally, getting a diesel engine would cost more, but in this case, the price was the same for both. The tdi’s obvious advantage is better economy, although Audi’s official statistics show that it is slower than the tfsi. We wouldn’t travel far enough to benefit from diesel, so if the tfsi were less expensive to purchase, it would be a no-brainer.
Beyond the obvious advantages of performance over economy, what are the disadvantages of each engine?
TFSI or TSI, which engine is superior?
Conclusion: Although the two engines are quite similar, the TSI replaced the Turbo FSI and might have experienced more issues. Although these engines are not the most dependable, if they are properly maintained, we have seen both of them survive longer than 200,000 miles.
About Trey
I have a passion for Volkswagen and Audi vehicles and spend my weekends working on them. I also appreciate assisting others by offering insightful and correct knowledge in the field of automobiles. I’ve worked in the automotive sector for at least ten years, and I make it a point to never stop learning new things. I hope that my posts reflect this passion and help the readers.
TFSIis it a turbo?
The first turbocharged direct injection engine in the world is the TFSI (Turbo fuel stratified injection). This technology offers increased fuel efficiency and improved engine responsiveness in addition to higher power output and lower emissions.
TFSI has a twin turbo?
The new 4.0 TFSI has “cylinder on demand technology” and is a potent V8 with dual turbochargers. Four of its cylinders are turned off when it is working at a partial load. As a result, fuel consumption is often reduced by 5%.
Which Audi engine is the most dependable?
Additionally, Volkswagen added the VR6 engine to the Audi lineup. According to MotorReviewer, the Q7 received a 3.6-liter version of the 3.2-liter VR6 found in the R32, while the Audi TT and A3 had the same engine. The VR6 isn’t flawless, but its two primary problemscoolant pipe failure and ignition coil/coil pack failurehave been fixed with more robust replacement parts.
What is the problem?
The piston rings are the cause of the issue. Oil burns and consumes a lot of oil when a small amount seeps into cylinders. Oil consumption worsens when the size of the grooves in the bores increases and more oil leaks around the pistons (usually after 50k80k km). For the 2.0 engines, the Audi specification states that 0.5 liters of oil may be used every 1000 kilometers.
Is my engine affected?
You may run a quick test to see whether the engine in your automobile uses excessive amounts of oil.
- Refill your oil.
- Set your odometer to zero.
- Drive up until the notification “oil level too low” appears.
Your engine uses too much oil if you’ve only traveled less than 4000 kilometers. Audi won’t admit it, though, until it travels less than 2000 kilometers. Furthermore, you must have an official consumption test performed by an authorized Audi dealer if you want Audi to perform any corrective work.
What options do I have?
- You can disregard it and simply keep adding engine oil until the engine breaks down.

How trustworthy is the 2.0 TFSI engine?
Overall, we’d say “yeah”! It is obvious that the 2.0 TFSI engine must be at least somewhat dependable because it has been utilized in numerous models across numerous continents for many years.
Another question is whether it can be trusted in comparison to its rivals. Over 50,000 warranty direct policies are used to gather the data for the Warranty Index.
There are only 2 Audi vehicles on the top 100 list at the moment. No specs are provided, although both of these are compatible with the 2.0 TFSI engine. Additionally, the TT, which ranks 44th most trustworthy, is the highest-ranking Audi.
The 2.0 TFSI engine is often available in Audi’s medium- to large-sized vehicles, including the A3, A4, A5, and A6. These automobiles compete directly with models from the Mercedes C and E Class and the BMW saloon lineup.
TFSI is it turbocharged?
Maintaining a spot on the Ward’s 10 Best Engines list is difficult. Every year, we put a returning candidate through a new challenge and evaluate whether the standard is still relevant.
Audi’s TFSI supercharged 3.0L V-6 has provided the solution for a third consecutive year and never ceases to wow with its incredible power, finesse, and efficiency.
This year, we assessed the direct-injection V-6 in the larger 4,045 lb (1,835 kg) A6 with an 8-speed automatic transmission after testing it the previous two years in the comparatively compact 3,637 lb (1,650 kg) S4 with a 6-speed manual transmission.
Even though the A6’s engine weighs 400 pounds (181 kilograms) more than the S4’s and makes 310 horsepower as opposed to 333 horsepower, the engine did not seem to notice the difference.
This is due to the engine’s continued ability to produce an astounding 325 lb.-ft. (441 Nm) of torque between 2,900 and 4,500 rpm. When asked, it responds with awe-inspiringly tremendous acceleration while maintaining the highest level of polish.
Before diesel engines became commonplace, nothing with fewer cylinders could equal a V-8’s low-end torque.
Today, it is abundantly obvious that forced induction and gasoline direct injection may let smaller displacement V-6s defeat larger displacement V-8s at their own game by providing stump-pulling torque at lower engine speeds while providing better fuel efficiency. The 3.0L TFSI makes V-8s seem antiquated in sophisticated autobahn burners like the S4 and A6.
The A6 application accelerates from 0 to 60 mph (97 km/h) in 5.3 seconds, which is 0.4 seconds slower than the lighter S4. However, the larger vehicle actually achieves greater fuel efficiency because to the new 8-speed automatic, achieving 19/28 mpg (12.4-8.4 L/100 km) as opposed to 18/27 (13-8.7 L/100 km).
On the highway, it’s not hard to achieve close to 30 mpg (7.8 L/100 km), but our average across 258 miles (415 km) is 22.4 mpg (10.5 L/100 km). It would have been simple to perform better, but the boost from the supercharger is so intoxicating that we were unable to control our right foot.
The Audi V-6 sets the bar extremely high in several areas in addition to performance. It illustrates that even a relatively exotic engine can be adaptable, and that supercharging can still compete with turbocharging as an induction approach for mainstream vehicles (as well as over-the-top performance versions). Along with the larger A7 5-door sedan and Q7 cross/utility vehicle, it also powers the S4 and A6.
The engine is also utilized in variations of the VW Touareg, Porsche Cayenne, and Panamera Hybrid, all of which are brands owned by Volkswagen, Audi’s parent company.
This inspirational masterwork had little issue making the 2012 list with a resume like that. It will be intriguing to watch whether it has such a simple time the next year.
How durable are Audi engines?
Out of 32 automotive manufactures, Audi is presently ranked 28th in terms of dependability. A well driven and maintained Audi should last between 10 and 13 years, or 150,000 to 200,000 kilometres. Audis are renowned for their technology, style, performance, and beautifully designed interiors. They also have an all-wheel drive system called Quattro.
Although the Audi brand dates back to 1899, it wasn’t until Volkswagen acquired the company in the late 1960s that the automobiles started to become well-known internationally. This fast car has always been at the forefront of technology.
Long before other automakers, the business started conducting crash tests, and in 2010, their first completely autonomous car successfully completed the 20-kilometer Pikes Peak circuit without a driver.
Despite the fact that Audi has many positive qualities, its dependability is not one of them. Audi is not an exception to the rule that high performance requires hefty upkeep.
Diesel versus gasoline, which Audi engine is superior?
It is evident that supporting one model practically cannot be done. Both the diesel and gasoline versions of the Audi A4 have advantages and disadvantages. You are entirely responsible for deciding whether to use a gasoline or diesel mill. There are several things that affect how decisions are made. Please keep in mind that diesel vehicles have cheap operating costs and reduced maintenance requirements compared to gasoline vehicles. Because diesel engines must handle greater pressure than a typical petrol engine due to higher combustion pressure, they require routine maintenance such as fluid changes. Simply said, diesel requires more maintenance and has lower running costs, and vice versa. Oh, the petrol one, this is real.
It should be remembered that a diesel variation has more power and torque than a petrol run variant when comparing gasoline and diesel run variants.
174.33 horsepower at 4200 rpm and 380 Nm at 1750 2500 rpm as opposed to 167 bhp at 380 06 200 rpm and 320 Nm at 140 03 700 rpm. Additionally, diesel outperforms petrol run trims handsomely in terms of mileage. Diesel vehicles achieve 16.55 kph in the city and 17.11 kph on the highway, compared to 12.32 kph in the city and 15.64 kph on the highway for gasoline vehicles.
The decision to choose an Audi A4 with a diesel or gasoline engine depends on the priorities of the buyer. In comparison to its petrol-powered counterpart, the diesel model offers better engine power and mileage. Additionally, a diesel-powered model can carry a bigger load because to the higher engine power (passenger and cargo). However, the engine is more noisy, more combustible, and expensive to maintain. On the other hand, the petrol version is lightweight and requires little upkeep.
Which of the outstanding sedans, the Audi A4 petrol or diesel, you choose will depend on your own preferences. You may also make a choice based on the needs you have for running. You can choose the diesel version if your daily commute is more than 60 to 70 km, but if it’s only 20 to 50 km, you should choose the petrol version. Both engines get about identical mileage. Although the power output of the diesel and gasoline engines is nearly equal, the diesel variant offers more torque.
If we choose one of these two, it would be unfair to the other. Diesel and gasoline each have advantages and disadvantages. For instance, the diesel engine claims to require high maintenance because it puts more strain on the engine yet is great for longer trips and provides superb low end torque and power while operating at low cost. On the other side, gasoline is better for city driving since it provides you more power and allows you to drive faster, but it has less maintenance and a high running cost because of the price of the fuel.
