Is there a way to delete the lamp for the error indicator of the engine control? The reason is that the car was ticking like crazy when speeding and the lamp lit (but only after minutes) (the engine had already run warm). My guess was humidity or bad fuel, because it now runs nicely. A visit to the workshop resulted in reading out (by 23€) that everything is possible: valves, control, ignition cables, coils, candles,…. That was not very productive, because the cables, coils and candles were exchanged a year ago (similar error picture at that time). 100 meters after the workshop the lamp lights up again, even though the engine is brav purring. That’s why my question, because I would like to know how often the “error” appears. Oh yes: S40 gasoline 1.6l 109hp BJ2001
