Hi, I got an Audi 80 with the 2L (133PS machine). Since I don’t know how to do that, I have 2 questions. The first one is: almost every morning, when I turn around the key, he only hums. I assume that the starter is a bit stuck. As soon as the starter spins, it starts immediately. Is there any way to fix the problem without buying and installing a new one? And the second question refers to the radio. In my opinion, it’s already retrofitted (blue point cassette radio). I turn it off. When I turn off the ignition it’s still in operation (clock time is displayed). Then I always take out the removable cover. Is that necessary? Does it make a difference for the battery or similar?
