Mercedes-Benz C32 AMG Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mercedes-Benz C32 AMG


A dead battery can be caused by a faulty seat control module that does not properly shut down.  Spilling liquids on the front seats can cause these modules to fail.

The electrical connector at the automatic transmission may leak fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. At that point, a new harness and control module may be necessary to correct this problem.

The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance. Communicating these specific symptoms to your technician can save diagnostic time.

Issues: 1) MB is the only car manufacturer in the world that cannot make a decent lock actuator. Unlike the electric ones which work for twenty years, the vacuum units on the MB fail regularly.
