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 camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.
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.

I bought my c230 after driving a sporty Acura RSX type-S for a couple of years. The comfort was the first thing that I noticed. 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...
