Why do the warning lights on the dashboard of the Mercedes A-Class W168 come on?
Years 1997-2004

Answer

It may happen that all the lights come on at the same time and remain on, as well as the analog hands remain stationary. In this case it is suggested to make a diagnosis to analyze the probable cause. Also check the effectiveness of the battery and, if it is discharged or no longer effective, recharge or replace it. Unfortunately, in these cases it is often not easy to trace the origin of the defect which could concern the alternator, the brake pedal sensor, the dibimeter or the EGR.
