Can you trust TFSI engines?
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 a 1.4 TFSI Audi A4 any good?
If you read our early impressions after testing the A4 at launch, you’ll know that we thought Audi’s junior executive range was impressive.
It is a serious contender for best in class honors thanks to exceptional driving performance, a fantastic cabin, and wonderful hi-tech amenities.
A long-term evaluation of an Avant model gave us the impression that this is one of the best Audis in recent memory. It is attractive, frugal, roomy, and just so simple to live with.
However, because Audi is Audi, there are always new products to add to the lineup or voids to be filled. Which leads us to the test vehicle, a smaller gasoline saloon that is powered by a 1.4-liter TFSI gasoline engine.
Once you get past the lack of displacement, you’ll quickly start to admire the brilliant turbocharging technology that allows these small engines to function in such large vehicles. With 148 bhp, it matches the 2.0 TDI diesel’s top power output and provides genuinely sparky performance, accelerating quickly when necessary and cruising at a leisurely pace on the highway. Even the mid-range torque that the diesel has available isn’t really missed.
Driving-wise, the base A4 is comparable to its stablemates with larger engines, but how does it compare to the diesel on paper? The Sport-spec car under examination costs 27,300 instead of 30,550, and has CO2 emissions of 126g/km as opposed to the diesel’s 99g/km. As a result of being $80 a year less expensive for a taxpayer who pays 40% in taxes, diesel has a modest benefit in taxation terms. Both are under the 18% range for reducing allowances.
Where the diesel clearly excels is in fuel efficiency (74.3 mpg vs. 53.3 mpg). The diesel will be the obvious choice for drivers who log more miles, but those who log fewer miles per year should give the TFSI option some thought.
Verdict:
A4’s 1.4 TFSI engine delivers respectable performance in a well-designed vehicle. If your drivers don’t go a lot of miles, they might benefit more from one than from the common diesel.
Is the 1.4 TFSI Audi A3 a nice car?
With its ability to check off the boxes for quality, refinement, economy, and practicality, the Audi A3 Sportback has the potential to be the ideal family hatchback. Does it then?
Many people may view the Audi A3 as a Volkswagen Golf dressed up, but there’s no disputing that this latest iteration looks far superior than the VW. The S Line version of the A3 Sportback has sharper front and rear bumpers and rides on 17-inch alloy wheels (18-inch are available). The A3 Sportback also has a lower ride height than Sport and SE variants, which contributes to its street cred and stance (but a mixed ride, as you will find out below).
The LED daytime running lights on my test vehicle are stunning. No matter how bright or gloomy the environment is outdoors, they make the A3 stand out. The twin exhaust tips and the angled taillights, which sort of fall between those of the Golf and the Leon, are other appealing visual features.
The 1.4-liter TFSI engine comes in two different power outputs: 140 horsepower and 122 bhp. The more potent of the two was in my test vehicle. Unexpectedly, the more potent model emits less CO2 than the less potent one, which is a great argument for choosing the potent model. You’ll be glad you did if you do. With more than enough power and torque, the 1.4 TFSI engine is a dream, making all forms of driving enjoyable. The 6-speed manual transmission that came with my car is smooth and has precisely spaced gear ratios. The engine is whisper quiet and does not vibrate during start-up, idling, or driving about town (unlike in the 1.6 TDI).
The engine is still polished while moving quickly. The majority of A3 sales will be diesels, but new TFSI engines outperform them because they are quieter, make a better sound, and are faster when driven properly.
The journey was one thing that shocked me. When I tested a Sport A3, the damping and handling were excellent; they struck the ideal balance. The A3 can occasionally feel uncomfortably rough in S Line trim, especially while in Sport mode. In this setting, the steering becomes firmer and the A3 simply assumes a heavier-than-it-is feeling.
The inside of the A3 S Line isn’t hit or miss even though the ride is. Excellent work was done by Audi in modernizing the interior of the previous model (which, by the way, was still fine when this new A3 came out). Prepare yourself for this if you’ve recently sat in a new Seat Leon or VW Golf; the A3 is far superior in terms of quality, and the differences are night and day. That is not to argue that the interiors of those two vehicles are subpar; on the contrary, they are magnificent. The A3 just takes interior design to a higher level. Actually, the quality rivals that of a BMW 1-Series.
The cabin materials, which are all either soft touch or incredibly strong textured plastic or metal, give you the first sense of the quality. When you use any switches or controls, fire up the engine, or begin to pull away, it hits you again. At any speed, the A3 is incredibly quiet, and everything feels excellent.
The Audi A3 Sportback 1.4 TFSI 140 S Line has a 6-speed manual transmission, a CO2 rating of 112 g/km, and a combined fuel economy of 58.9 mpg. With S-Tronic, it returns 60.1 miles per gallon and has a CO2 rating of 110 g/km. However, S-Tronic vehicles cost about 1,500 more than manual vehicles. According to those CO2 values, the manual will cost $30 year in taxes and the S-Tronic $20.
On a 150-mile round trip, I got 47.8 miles per gallon on average. The A3 never dropped below 38 miles per gallon on short 20-mile trips.
Audi offers three trim levels: SE, Sport, and S Line. The highest trim specification is S Line. There was a ton of stuff in my car, but I was shocked to find that a lot of it was optionalyou had to pay extra to receive it. Some of the extras that come with an A3 Sportback S Line are cruise control, heated seats, power folding mirrors, and satellite navigation. I am aware that these are available in “Packs,” but this is a mid-range vehicle with top specifications. Why shouldn’t the Audi come standard with cruise control and satellite navigation like the Hyundais do?
I veered off course after learning that several of the usual equipment on Japanese cars are extras on this expensive hatchback. This is because the vehicle is of the highest caliber; why should anyone be required to pay more for a feature on a vehicle of this caliber?
The Audi A3 Sportback makes a great family vehicle. The 1.4 TFSI engine is a gem, offering efficiency and refinement. Its good appearance and luxurious interior are likely to win over any prospective purchasers. The major issue I have with the A3 Sportback in S Line trim is that I’m not sure it’s a fair value for the money; while S Line will have strong residuals, basic models provide very little. Your only options are Bluetooth and a touch-screen media player. For what are today regarded as standard features, you are need to spend more. The ride may also be choppy. Despite the spec, I enjoy this automobile. I advise purchasing a 1.4 TFSI Sport and adding cruise control and a winter package with the money you save.
What is the best Audi engine?
The Top 7 Audi Engines of All Time

- Engine: 2.7 V6 BITURBO.
- TFSI Engine 2.5.
- FSI Engine 5.2.
- TDI 3.0 Engine
- V8 engine, 4.2.
- Turbo engine, 2.2.
Is TFSI superior to TDI?
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?
How trustworthy is the Audi A4 TFSI?
Although customers continue to be impressed by Audi’s renowned interiors, its overall score in our Driver Power poll is lowered due to problems with flexibility, reliability, operating costs, the ride, and handling.
Audi A4 reliability
In our 2021 Driver Power owner satisfaction survey of vehicles presently sold in the UK, the Audi A4 received a low dependability rating, placing 65th out of 75 vehicles. Unexpectedly, the A4 scored highly in the MPG and operating expense categories, which is remarkable for an executive vehicle. Although you mentioned that its practicality and infotainment should be improved, it also performed reasonably well for its engine and transmissions.
Despite coming in ahead of BMW, Audi as a brand placed a rather unsatisfactory 23rd out of the 29 manufacturers reviewed in 2021. In the first year of ownership, 16% of Audi owners said they had reported at least one problem.
How well-built are Audi A4s?
What Makes the Audi A4 Good? Yes, the A4 is a fantastic premium compact car for 2021. This car provides three potent turbocharged engine options, a smooth ride, and excellent gas efficiency predictions.
Does the Audi A4 lack power?
Only petrol engines are offered for the Audi A4 facelift. It has a 7-speed DSG automatic transmission and a 2.0-liter turbocharged petrol engine with 190PS and 320Nm of torque. It claims to have a fuel efficiency of 17.42kmpl.
Is Audi A4 Facelift Underpowered?
The A4 facelift has sufficient power. The sedan is enjoyable to drive both in the city and on the highway thanks to its 2.0-liter turbo engine. Only after 3000 rpm is the engine audible due to its extreme quietness.
TFSI stands for what?
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.
