I have had this problem with the car (mk4 golf 1.4 16v ) for several days. When I enter the key to turn it on, almost all the lights on the dashboard turn on, while the clock display and mileage do not turn on. After I try it for about 20 minutes then the car turns on, the clock shows 0:00 and it goes on until it turns off again the same thing repeats the problem:
The second link indicates the moment when suddenly the problem fixes itself ( but this is momentary because as I told you above it happens again later ):
What do you think about this problem?
