W212 Airmatic Malfunction Code 552A1C & 556684 - Valve replacement or leaky bags?
552A1C Status: Current - The right rear level sensor has a malfunction. The voltage is outside the permissible range
556684 Status: Historic - The left rear is outside the tolerance. There is a signal below the permissible limit value
Does anyone know if these codes refer to leaking bags or a levelling valve replacement? I've booked the car into a garage tomorrow and I wish to make sure I get charged for the correct parts.
Any help would be appreciated.
Finally, does anyone know if there is a definitive error code list posted somewhere?
