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.

2005 Mercedes-Benz C320 Problems
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.
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 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.

2005 Mercedes-Benz C320 Reviews
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.
