Hello guys, I got an Audi 100CS a week ago. The following problems have occurred since I got the car. If the engine is cold and I want to accelerate from a low speed I almost run out of engine. Yesterday it went out on the mountain. What I also noticed is when I turn off the engine and after about 10-15min on comes an error message in the front of the display with a red oil lamp and 3x ring. According to the user manual I have to turn off the car. n and call the Audi Service. If I’m driving on the highway 100-120 km/h now it’s ringing away again. Have you got an idea what that could be. I’m going to tap on the gearbox. I think it’s licking. However, I couldn’t find a bigger oil strip. But if I look into the engine compartment then I see very weak traces of oil on the gearbox housing. What would cost me to get a transmission close again or is that possible at all. I thank you for your help
