Well, I was hoping not to have to write here again so quickly… I bought the linked Colt (CZ3 Lim.3 1.1 Inform, Bj 2006, 136,000km, gasoline 55 kW (75hp)) and now drove about 1,500km. Today I drove about 30km without any problems and parked the car. He then stood for about 5 hours in the blazing sun (who knows if that is important…). When I started it in the evening, the engine warning light came out and didn’t go out. In addition, the driving was uneven. As long as it lit up (1-3 seconds), the speedometer display no longer worked (much to 0). When it extinguished what happened quickly, the speedometer worked again. The same thing happened once, when all the warning lights lit up at the same time (EPS, buckles, oil, temperature). It is clear that I will bring the car to the workshop (since I am on Sunday a road trip). but does anyone have an idea of what the mistakes might be related to? MfG, Ludger
