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 superior 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?
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 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.
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.

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.
Why burn oil in Audis?
Your Audi A4’s TFSI gasoline engine has a design flaw that causes it to burn through oil quickly if your vehicle is older than model year 2012. (Take note that a quart of oil can be used every 1,000 miles according to Audi specifications for the 2.0 engines.) These engines’ fundamental issue is that the piston rings permit very small amounts of oil to seep into the cylinders. It burns once it’s in the cylinders, which uses a lot of oil.
Your Audi A4 may be overheating if it is a model year 2013 or later due to a coolant leak (water pump, radiator, etc.), a defective radiator fan, or a malfunctioning thermostat.
Whatever the source, you might not be aware that you’re using oil quickly until you see the “Add 1 qt. Oil” sign on your dash. It is OK to continue driving after receiving this warning, but you should add a quart of the proper quality of oil as soon as you can.
The issue will worsen over time, reducing the amount of time you can drive before adding oil and increasing the frequency at which you must top off your oil. Many people accept doing this since it’s less expensive than the cost of the repair, but the harm it causes to your engine isn’t worth the short-term savings.
TFSI is turbocharged and supercharged.
TFSI just has a turbo. The TSi sports a turbocharger, a supercharger, and twin charging. The 1.4 TSi engine can be weak since it cannot support both a turbo and a supercharger.
Is the 1.4 TFSI Audi engine reliable?
The 1.4 TFSI is a fantastic automobile engine with a reputation for dependability, effectiveness, and power. It does, however, have issues, just like any other vehicle. Failure of the turbocharger is the most frequent issue, and it can be expensive to fix. Fortunately, if the product is under three years old, the manufacturer’s guarantee will pay for repairs. Your Audi will last for many years if you take good care of it.
We sincerely hope that our information on the most typical Audi 1.4 TFSI engine issues was helpful. Please feel free to remark below if you have experienced any problems of your own using this engine.
