Once car is put into reverse it launches back ? Also in first one put in cost it wants to move practically forward .
Car slammed into different gear, wasn't able to shift into 2nd and threw gearbox malfunction and TPMS errors. Thankfully I was near home and able to make it there without an accident or being stranded, but my car is now immobile. I spoke with audi and they said it will likely be a $4k repair (mechatronics unit). After researching this more, it seems to be a common problem with these cars. It can happen at any time and can be extremely dangerous. There's also a pending class action lawsuit to get audi to do the right thing and recall these cars and fix them.
My car flashed gearbox malfunction while driving down interstate I-264 in louisville ky. Car seamed fine for about 2 miles and then suddenly went limp and I had no gears. Had to hit flashers and coast into median. Was almost hit by semi truck. Repair shop could not find anything wrong. Happened again 1 day after getting it back from shop. Taking it to audi now. I have read that this is a common problem.
Mechatronic issues.
The whole car jerked when going to 2nd gear and then thetpms, no reverse, and gear malfunction lights comes on. 2nd, 4th, 6th, and reverse gear are gone. Restarting the car cleared the warning and drove fine for 10 miles before it happens again. Try restarting again to clear the warning but light will come back on when going to 2nd or reverse.
Gearbox failure seems to be common issue on the 2010 model. Seems a replacement mechatronics unit or full transmission will need to be done to resolve the issue.
It happened again today driving down the highway going up to speed, at about 50 MPH I got a "gearbox malfunction" error message in the cluster and it would not let me accelerate anymore, it was like the car was in neutral and pressing the accelerator pedal would just rev up the engine. The mechatronics unit on these vehicles are faulty, I know 2 other s4 owners with the years of 2011 and 2012 who also had their mechatronics fail on their s4. Along with the gearbox malfunction error also comes "parking brake error" who knows what in the world can happen when that message comes up. Is it going to suddenly apply the electronic parking brake going 50-70 MPH down the highway and cause a possibility of a very bad accident? The repair is very pricey for the mechatronic unit that goes bad, it is no coincidence many of these s4 models have these go bad.
Vehicle was in motion, the mechatronics unit on my car is failing and just many many other vehicles of the same make, model, and year. The vehicle can stop engaging gears at any speed and can be very dangerous at any speed, especially on the highway
