2010 C300 Manual Brake Hold Issue




If the HOLD indicator is not on in the instrument cluster, the ECU does not think the brakes are engaged.
There may be another issue with the brake system, like debris in the lines causing the rear brakes not to release fully. Or the parking brake may be adjusted incorrectly.
Were the brakes serviced by Mercedes or an independent familiar with Mercedes vehicles? My experience with national brake repair chains that do well on domestic and Japanese models is very poor on Mercedes and BMW.
The car should be scanned for brake/ABS/ESP system errors, then physical diagnostics can be continued.
