I tried to turn the car off and restart it, but the check engine light would keep showing and the the gears would again rev too high durring shifts and would eventually all light up again and fall into safemode after a few minutes. As of now the car can drive and go into reverse and even tiptronic mode, and drive forward and go up 25-30 mph but the first gear gets stuck on a high RPM (4,000-6,000) when shifting and always falls into safemode eventually. 2 days prior to the problem, we had the oil changed as well as the valve gaskets & camshaft breather hose replaced. the car ran perfectly for 2 days and then this problem suddenly occurred. after taking it to the audi dealer, their diagnostic said there were incorrect gear ratios as well as other fault codes. it is hard to know what we need to replace at this point and weather its a electrical or mechanical issue.
Sounds like a solenoid to me,if this tranny is so equipped.
