Ever since the battery in my E320 (97) ran flat the airbag warning light stays on. the local MB dealer want £67 ($125) to reset it - 5 minutes labour, 1 hour billable, they tell me. Can I do this myself and how?
I've now telephone 15 MB dealers and all of them say a flat battery will set the airbag warning light. All of them can reset the switch for 1 hours labour charge. This is criminal, there must be a way to unset this switch. Is it a relay or is is a firmware switch. Does anyone know?
im not sure if this is the same problem but my srs light is now starting to come on when the passenger seat is not in use, could it be poor connections or is it needing a reset after having battery disconnected for ice install?
