Mercedes-Benz C320 Problems
Clicking Noise From Behind Center of Dash
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.
Dead Battery Due to Failed Seat Control Module
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.
Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
Transmission May Leak Fluid and Damage Control Module
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.
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.

Today, when I got in the car to go to work, the front driver seat was all the way forward and would not move back. I had to drive all the way to work with the steering almost touching my chest. Tried everything and I can hera a click when I try to move the seat. I guess the motor went bad and there is no way to manually move the seat until I can replace it. Any ideas..?
My experience with MB has been a roller coaster. I bought the car with high mileage. I keep it serviced. Here are the problems I have had with the car. My passenger door handle broke from the inside. The passenger seat motor has a shortage. It works when it wants to work. My air conditioner on the passenger side does not blow out through the vents, it blow out on the floor. My engine light came on..I needed a new EGR or ERG value and pipe...It was clogged..never been replaced before and the person b4 me didnt maintain the car well.

At 48000 miles an oil leak showed up on the right side of the engine. At 58000 miles this message showed up "engine oil sensor malfunction, go to workshop". $611 to fix and was not given any reason why it broke. Inside passenger side grab handle just broke, very cheap workmanship. Be careful when you park because front spoiler will be damaged by a parking lot's wheel stopper. Very low front.
