2003 Mercedes-Benz C230 Problems

Inside grab handles, the upholstery on the center console cover, and door trim panels can delaminate. Most commonly replacement of the affected part is necessary.

The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.

Oil can leak into the engine wiring harness from the camshaft sensor. If the leaky sensor is not repaired, the oil can migrate through the wires and possibly damage the engine control unit. Have the sensor and harness checked regularly.

The seats are accommodating and the electronic seat adjustment for both driver and passenger is a great addition. The ride is smooth for such a sporty car, and the transmission shifts with little hesitation. Smooth is what I have to say about the driving experience. If...

I am buying a 2003 c230 at a local dealer for 7000.00, they are having the valves done and the guy said it would run 1800 and split the cost with me or he would just wholesale it. It is in great shape otherwise. The compression runs 160-160-160-100, with cyl # 1 being the issue.....is this common at 100k mi?
