2004 Mercedes-Benz C230 Problems

Inside Grab Handles/Upholstery/Door Trim Panels May Delaminate

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.

Camshaft Adjuster Solenoid Failure

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.

Oil Leak Into Wiring Harness From Camshaft Solenoid Switch

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.

One or More Seat Belts May Not Lock as Designed

Some seat belt buckles may have a burr on a metal component of the locking mechanism. This could prevent the seat belt from locking under certain conditions.

This recall is expected to begin on December 22, 2003. The Mercedes-Benz recall number is 2003 120006.
