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.
Is TFSI preferable to TSI?
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.
Audi TFSI or TDI: Which is superior?
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?
Is TFSI short for turbocharged?
The idea of combining direct fuel injection, also known as FSI by Audi, with a supercharger or a turbocharger is known as TFSI, short for Turbocharged Fuel Stratified Injection.
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 exactly does GTI mean?
What exactly does Volkswagen GTI mean? Grand Touring Injection is the abbreviation. For its direct fuel injection system, Volkswagen employs. The 1976 Volkswagen Golf GTI introduced GTI technology for the first time, over 40 years ago.
What distinguishes TFSI and FSI from one another?
Here are some potentially foolish questions, and I’ve looked around the topic for information but haven’t found anything.
I own a 2008 MK5 Jetta, model number 2.0 TFSI sport, according to the information sticker in the user manual. The car’s rear is marked with the TSI logo. FSI is on the engine lid. Who has the information on all of this? I am aware that the TFSI is 147kw thanks to the manual’s tables. I may presume the T stands for turbo, but the FSI’s also have a turbo and are depicted in the manual with less Kw. What makes the engines different, given that they are both 2.0, and how does it affect the power difference? Furthermore, I’m not even sure if my car even has a turbo because I have no idea how to remove the engine cover to check behind it and I can’t hear or see it. Someone please provide some clarity on this. Just to add, I have read that the TSI engine uses a timing chain rather than a timing belt, albeit this may only be true for more recent vehicles.
That’s not a foolish question at all, and it shows how confusing VW’s constant renaming of their engines has made things. You won’t be able to hear the turbo, but you can tell it has one when you put the right foot down. I never could in my Jetta.
With regard to the Jetta specifically, there were two petrol engines available when VW first sold the MKV Jetta in Australia: the 2.0 FSI, a naturally aspirated engine with, in my memory, a power output of about 110KW, and the 2.0TFSI, a turbocharged engine with a rating of 147KW. Fuel Stratified Injection (FSI) refers to a system of intake tract flaps that produce a certain form of turbulence, and TFSI, logically, stands for Turbocharged FSI.
I believe from memory that the naturally aspirated Jettas had either no badge or a 2.0 FSI (no red coloring) badge to distinguish themselves from the turbo cars. Some of the original TFSI Jettas did not have a badge indicating which engine they had in them, while others (like the one I had) was bagged 2.0 FSI. Isn’t that confusing? You have not yet seen anything! LOL
Then VW debuted the Golf’s 1.4 twincharger engine, known as the TSI. I’m not sure what the abbreviation meant anymore, but it looked to refer to the engine’s dual super- and turbochargers.
I think this was in 2007 or 2008, and it may have coincided with the switch from Mexican to South African production of the Jetta for the Australian market. This is where it gets really confusing! VW then changed the designation of the Jettas with the 2.0TFSI engine to TSI even though, as you pointed out, the engine cover is badged FSI.
When my Jetta 2.0TFSI was being serviced at a Sydney VW dealer, I was given a loaner 2.0TSI Jetta. When I returned the loaner, the service advisor asked me what I thought of the 2.0TSI-powered vehicle before telling me that it had a 2.0 twincharger engine, which is obviously not true. If VW service advisors are saying this, it really emphasizes how perplexing everything is.
I currently own a 2009 EOS 2.0TSI, which is obviously equipped with the same 2.0TFSI engine that the Jetta was equipped with. Later EOSs are equipped with a 155TSI (single charged) engine, which is another distinct engine; I believe this is the timing chain engine you refer to.
What does Audi FSI mean?
Questions have been raised regarding the distinctions between the 2.0 liter VW/Audi FSI and TSI engines. To assist you understand how the TSI powerplant evolved from the FSI, I’ll try to emphasize the distinctions between them. I won’t go into every distinction, but I’ll try to cover the most important ones.
Before we go too far into detailing the changes, let me make it clear that VW/Audi has utilized the marketing jargon TSI, FSI, and TFSI on a variety of models. It’s not always possible to tell one from the other only by looking at the engine cover.
FSI stands for “The abbreviation TSI stands for “turbo stratified injection,” fuel stratified injection, or “fuel straight injection.” By producing a fuel rich mixture, these fuel injection systems enable engines to run at lean air-to-fuel ratios (higher fuel economy) “stratified charge close to the spark plug, but this has an enhanced NOx side effect (nitrogen oxide). Although catalytic converters are capable of removing excess NOx, the high sulfur level of American fuel contaminates and degrades them. While FSI engines in Europe improve power and efficiency through a lean burn, the American version uses the same air-to-fuel ratio as port-injected engines.
We can therefore infer from this description that we are discussing a particular type of injection system rather than an engine block. Modern VW/Audi models use TSI, FSI, and TFSI on a variety of engines, including the 3.0, 4.0, and 4.2 liter models. The differences between the EA113 engine code, which is typically connected with the FSI, and the EA888 engine code, which is typically linked with the TSI, are what we are actually comparing when we talk about the 2.0TSI and 2.0FSI.
Because it has become standard practice to use them interchangeably for the EA113 and EA888 codes, I will continue to refer to the differences between the FSI and TSI in this article rather than the engine codes.
- 1984 cc displacement
- 200 hp maximum
- 206 lb-ft of maximum torque
- 4 valves each cylinder
- Bohr: 82.5mm
- stroke of 92.8mm
- Order of Fire: 1-3-4-2
- In the FSI, chain timing verses belt timing
- 9.6:1, which is a decrease from 10.5:1.
- Engine Control: From Bosch MED 9, Bosch MED 17.
- Addition of one oxygen sensor, bringing the total to three from two
- For added strength, the main bearing caps are now cross-bolted to the block.
- Piston undersides are sprayed with oil to increase cooling and lubrication.
- more evenly distributed cam shafts at the block’s middle
- improved feeding system that runs the high pressure fuel pump (HPFP) off of a specific exhaust cam lobe.
- improved cylinder head flow
- Internal updates that reduce internal parasitic loss
- a better PCV system
You can probably tell from the list that the TSI is unquestionably an evolution of the FSI. A widespread misperception is that because VW released the EA113 FSI in the expensive Golf R, it is more “tuner friendly.” This was really a result of VW’s production and development delays rather than the EA888 TSI’s strength and power limitations. You will witness some fantastic power coming from the most recent evolution of VW/small Audi’s displacement turbo architecture as the EA888 TSI platform develops.

Audi TFSI Quattro: what is it?
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. There is a TFSI engine available. versions with 4, 6, and V-8 cylinders.
Goodness of 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.
