Meal…. Hope someone can help me.. if I want to start my car early then I let him nudge for a moment then I let go of the key and only a second later it goes on, although I have released keys.. funny or??? furthermore I have to fill up my cool water weekly, after a week it is usually 5cm below minimal. but my control lamp shows nothing when the water gets scarce… and my temperature indicator somehow only goes when I throw in fresh water. otherwise only when it’s cold a few minutes.. achso and my hydros clapping since about 3500 km constantly as soon as it’s warm but I had the feeling today that it has become 50 % quieter after the water…. hope it can help mfg micha audi 80 2,3l 263000 km
