Hello dear Audi community, I am now proud owner of an Audi 100 2,3 e Limo, BJ ́88, 97000 km, 1 previous owner. I have already driven 250km with it and I have to say the thing is awesome! Since I don’t know about Audi and of course I don’t want to do anything wrong I turn to you with confidence! What do I have to bear in mind…? So timing belts were made 2 years ago and have been driven about 500km. Must be exchanged…? It is also a “quick” n” to hear…so at 30 in 2 gears…or hold on when you give gas… A clacker is also to be heard is the normal or do I have to worry??? Maybe the timing belt is moved you can check? The engine jumps relatively cold and then runs round for a short time. How can I fix that…? When the engine is warm Vibrates the whole car with…somehow so up and down…. So it does well up to 3000 rpm…I’m going to make it really slow. Until in the rotational number… I don’t trust myself anymore….macht mer yes net oder…? Otherwise the rear window heating does not work…how can I check it…? The fuses are all whole… Okay questions about questions….In any case, the car is super up to 2 – 3 places in the paint but that’s not bad either… Thank you very much in advance!
