2004 Audi S4 Owner Comments

I have a 2004 S4 which crunches when shifting into 2nd and 3rd gear. Audi replaced the synchros but the problem still persists. I have returned to the dealership numerous times but they keep telling me its normal. The crunches occurs everytime I drive it and also make it difficult to get into gear. The vehicles rpms will sometimes stick, keeping the vehicle moving when not under acceleration.

I have a 2004 Audi S4 that is slipping out of second gear... it is a known second gear synchro problem that Audi is ignoring. I have called Audi of America, and they admit there is an issue but still offer no help. The issue started at 55,000 miles which is 5K miles out of warranty.

I have a 2004 Audi S4 that had catastrophic failure at only 40,000 miles due to defective parts. The car has a problem where a tensioner I am told allows the motor to rev up even when your foot is not on the gas pedal and it causes damage to the motor. This has happened to many owners, most were under warranty because this part fails at such a low mileage, in some cases under 100 miles. Not only does this cause un safe situations for the driver as the engine can have this rev up happen multiple times before the engine fails, it also causes repairs that are very very costly and not worth while. When I took my car to the dealership they also discovered that my transmission is needing to be completely replaced. This is also due to defective metals used in the syncros is what I am told. Audi has no desire to correct the problem even though they have admitted none of the problems are due to abuse but rather weak parts. Even though I am out of warranty that should not make a difference when they have had so many of the same exact cases repaired to date. My kbb value is 23,500 and the repair cost would be around $17,500.
