Audi S4 problems

audi logo

The Audi S4 is the high performance variant of Audi's compact executive car A4. The original Audi S4, built from 1991 until 1994, was a performance-oriented version of Audi's 100 saloon/sedan. All subsequent S4s since 1997 have been based on the Audi A4; and as the A4 has evolved from one generation to the next, so has the S4.

Like its regular A4 counterpart, all S4 variants have had longitudinally oriented, front-mounted engines. All versions of the S4 have their transmission mounted immediately at the rear of the engine in a longitudinal orientation, in the form of a transaxle, and like all Audi "S" cars, are only available as standard with Audi's quattro all-wheel drive (AWD) system, using a Torsen-based centre differential system. A more powerful internal combustion engine, larger upgraded brakes, firmer suspension, larger wheels, and distinctive sheetmetal, styling clues and badging have always been amongst the many upgrades the S4 receives over its mainstream 100 and A4 siblings. In markets where the even higher-performance Audi RS 4 is not offered, the S4 is the top-of-the-line trim of the A4 family.

A single turbocharged 2.2-litre inline five-cylinder powered the original C4 version, and a 2.7-litre twin turbocharged V6 engine was found in the B5 generation. The B6 and B7 versions shared a common 4.2-litre V8 engine, the first time that a V8 engine was placed in a compact executive car, placing it in direct competition with the BMW M3 (3.2 L inline 6) and Mercedes-Benz C32 AMG (3.2-litre supercharged V6). The B8 generation uses a supercharged 3.0-litre V6 TFSI engine and competed with the BMW 335i, BMW 335i/340i xDrive, and Mercedes-Benz C350. The current B9 generation is powered by a turbocharged 3.0-litre V6 TFSI engine, with rivals including the BMW M340i xDrive and Mercedes-Benz C450 AMG/Mercedes-AMG C43 4MATIC.

All versions of the S4 have been manufactured at Audi's plant in Ingolstadt, Germany; they are, or have been available as a four-door five-seat saloon and a five-door five-seat Avant (Audi's name for an estate car/station wagon) body styles since the model's inception in 1991. A two-door four-seat Cabriolet (convertible) S4 variant was introduced as part of the B6 and B7 generation A4 lineups. The B8 Cabriolet has now been built off the A5 coupe body style and the "S" variant is marketed under the Audi S5 nameplate.

Common Audi S4 problems

The Audi S4 is known for several common problems that may affect its performance and reliability. One of the most frequently reported issues is poor starter motors, which can lead to the car not starting at all. This problem has been reported to occur in various models of the S4, and the solution is to fit a replacement starter motor.

Another common problem is with the electric windows, where the windows may not go up or down properly. This issue is often caused by a faulty window regulator, which can be fixed by either attempting to repair it or fitting a replacement window regulator.

The air conditioning system in the S4 has also been reported to have problems, particularly with the A/C condenser. If the air conditioning is not blowing out cold air, it may indicate a problem with the condenser, which can be resolved by fitting a replacement A/C condenser.

Headlight condensation is another issue that has been reported to affect the S4, particularly on cold mornings. This problem can be addressed by either leaving the condensed headlights, drilling holes at the bottom of the headlight covers to allow the water to drain out, or purchasing replacement headlights.

Coil pack failure is a common problem in several different Audis, including the S4. This issue can cause the engine to idle roughly and misfire. The solution is to fit a replacement coil pack, which can be a more expensive repair.

In addition to these issues, the S4 has also been reported to have problems with the timing chain tensioner, which can cause the engine to overheat. This issue has been reported to occur in the 2005 model, and the repair cost can be as high as $7,000.

The brakes have also been reported to be a problem in the S4, with some owners reporting that they had to have the brakes repaired at around 16,000 miles. This issue can be caused by faulty parts or drivers who don't brake properly.

Finally, some S4 owners have reported experiencing bucking, which can be a scary experience. This issue has been reported to occur when drivers are forced to brake suddenly and then immediately try to accelerate. The solution to this problem is not yet clear, but some owners have reported that it can be fixed by replacing the mechatronics unit.

In summary, the Audi S4 is known for several common problems that may affect its performance and reliability. These issues include poor starter motors, faulty window regulators, A/C condenser problems, headlight condensation, coil pack failure, timing chain tensioner issues, brake problems, and bucking. While some of these issues can be fixed relatively easily, others can be more expensive and may require more extensive repairs.

    Just a heads up, the thermostat in the 2011 Audi S4 has been known to be a bit faulty. You can easily find more information on it by doing a quick Google search. I personally had an issue with it, but Audi was kind enough to cover 10% of the $1200 repair cost since I was just over the 50K mile warranty. Other than that, it's a really fun and stylish car to drive!

    Hi there! I hope you're doing well. I wanted to share my experience with this car. While it's definitely fast and fun, I've noticed that the mpg isn't quite what I was hoping for. Additionally, I've had a few issues with electrical gremlins and some wear and tear on the Alcantara. I did have to replace the struts, which was a bit pricey, but overall I still enjoy driving it. Thanks for listening!

    This vehicle is incredibly versatile. While it may not be the fastest, sexiest, or safest car on the market, it is the perfect combination of all three. It has impressive speed, great looks, fit and finish, and all the necessary safety features such as curtain airbags and AWD. Additionally, it is incredibly useful year-round, especially in northern climates. However, it is important to note that this car may not be the most reliable option. Repairs can be expensive due to the tight packaging constraints of fitting in the v8. Common issues include clutches, valve cover gaskets, coil packs, tensioner pulleys, and starters. In my experience, the car visited the dealership four times in three months of ownership, with a total of two thousand in repairs (warrantied).

    This car was so much fun to drive and I loved it! However, now that it has 75k miles on it, I would be happy to get rid of it and never buy Audi again. Since I first bought it, there have been numerous problems that have added up to be quite outrageous! The original top failed during a rainstorm, causing the car to flood. I spent $9k replacing the control panel and rewiring the car. Unfortunately, the new top hasn't worked for a year and Audi USA is now involved, but still no satisfactory resolution. The starter broke and the car fan wouldn't shut off, draining the battery until I needed a tow to get it repaired. There have been so many other issues!

    If you're considering buying a sport model from Audi and you're a bit of an Audi enthusiast, it's important to do your research. I personally own a brand new S4 2018 model, and after just one year, in 2019, all four tires had completely worn out and split. As a lady driver who drives carefully, this was a real shock and made me feel quite nervous about driving. What's more, I was never told upfront that S Sport models require a special alignment that costs double due to a camera sensor, which can also cause tires to have a shorter lifespan. When I brought my S4 in for a second recall service, I was told that my tires were split and worn, and that this was a common issue with most S models. They even suggested that I consider getting a regular A model instead. It's frustrating to hear these things, and I've recently heard a lot of bad news about Audi and disappointments from their clients. One person said that their engine light came on just three days after buying their car, while another said that they started hearing strange noises after just a week. And once the 50,000 mile warranty is up, you'll be paying a substantial amount for parts and services. So, it's worth considering alternatives like BMW, Mercedes, or Porsche. Do your research and make an informed decision.

    I've owned my dark green on ecru leather S4 for over two years now, and I absolutely love it! While it can be costly to maintain, it's an incredibly safe and fun car to drive. It's roomy and comfortable for everyone, and the 5-speed transmission is simply beautiful. The turbo makes this car Porsche-fast, and with 107k miles on it, I'm considering keeping it forever. I get about 22 mpg, and with the lowered suspension and 17-inch BBS wheels, it stops, corners, and drives like a dream. With a five-star crash rating, I feel confident and poised behind the wheel. While some AMGs, WRXs, and R32s may know what this car is, to most it's a sleeper. I've only had it up to 125 mph, but I've heard it can easily reach 165 mph if you have the space to do it! If you're looking for a fun car, I highly recommend finding one and falling in love with it.

    This car is definitely a thrill to drive, but after a year of ownership, I've found it to be a bit impractical for my daily needs. With a fifteen gallon tank and only 15-18 miles to the gallon, I find myself filling up every other day. While the suspension is great on back roads, it can make small road imperfections feel like speed bumps on the highway, which can be a bit uncomfortable. Additionally, when I'm on the phone with clients, these imperfections can cause my voice to warble, which is less than ideal. Overall, I would say that this car is perfect for weekend joyrides, but not the best choice for a daily driver.

    Last 5 cars: Audi A4, Infinity G35, BMW 325, 328, 530. I was looking for a German car that was larger than a 3 series but smaller than a 5 series, and this Audi is just the right size. The back seats are spacious and comfortable, making it perfect for long drives. The car is in impeccable condition both inside and out. While the A4 was a great value, I found the sport seats to be less comfortable and the engine to be a bit noisy at high speeds. However, the S4 with its 330 HP 7-speed engine is a true powerhouse on the highway and handles city driving with ease. It may not be as agile as a BMW 3 series, but its larger size provides better stability at high speeds, making it a safer option. The Audi S4 is a rare gem that excels in style, composure, and beauty. It also boasts impressive fuel efficiency, with 29 MPG on the highway and 25 MPG in the city.

    After searching for a while and having owned many different brands and models before (BMW, Infiniti, Cadillac, Honda, Benz), I still find myself coming back to Audi. Their interiors are undoubtedly the most refined and well thought out in the world. I was torn between the M3 and S4, but after much searching, I was lucky enough to find a low-mileage, pristine S4 from a private seller. Having owned an A6 2.7T manual before, I was more than ready for a return. This car is amazing. It fits like a glove, handles like few others on the road, and is a practical hauler for life.
