Good morning I’m the ali driving a r230 500er For two days I’ve been lighting up abc with red light on uneven roads and going out again!??? The driving behavior is still neither lifting on nor off everything works as normal as usual. Once the vehicle also has a defensive drive up it went on and off after everything was back in order?? From what can the problem be animally happy if you would help me thank you in advance (ABC pump shock absorber front + rear new)
