My audi s4 2010 is having a mechatronic issue. while driving my vehicle down the street it dropped a gear and a error message popped up stating gearbox malfunction: no reverse gear. my vehicle was then unable to reverse and also kept dropping and jumping to different gears. it made a very unsafe and scary drive,i held up alot of traffic trying to drive back to my house. to get a new mechatronic cost betwenn 3-8 thousand dollars. also there are thousands of audi owners on the web who are having the same issue. i think audi should recall this part that is causing so many issues with the vehicle.
