2003 Mercedes-Benz C320 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2003 Mercedes-Benz C320

A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

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 engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Can a SRS error code be turned off without repairing the problem. Can a non mercedes shop clear a code?

The SRS light was on so they took it to a Mercedes shop to clear the code. When I got the car back the rear passenger seatbelt was not working. I called Mercedes and they said carmax wanted them to clear the code but they couldn't because it needed repaired. Car ex told them not to repair it....

Hatchback is very hard to open, sometimes will not open. Seems to be the actuator. How can I fix it ?
