Mercedes-Benz C240 4MATIC Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mercedes-Benz C240 4MATIC


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.

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. A new harness and control module may be necessary to correct this problem.

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.

I will write the following in capital letters to really drive the point home. DON'T EVER BUY A MERCEDES BENZ! DON'T EVER BUY A CAR FROM KEELER MOTORS, LOCATED IN LATHAN, NY! I bought a 2005 MB c240 4matic with 41k on it. Keeler MB sold it to me with a bent rim, a bad transmission seal, and they never changed the oil. The car has been a nightmare! I contacted MB USA and they did not even ...

As I aged, I've dreamed of buying a car that would last and grow old with me. That's why I first purchased a Mercedes C240 in 2003. Within 18 months it had twenty-eight, yes 28 repairs, ranging from fuel gauge malfunctions to a myriad of other annoying problems; reluctantly, the service center was my second home. I traded it in, not because of the astonishing number of horrific breakdowns and r...
