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.

2003 Mercedes-Benz C240 4MATIC Problems
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.
The sway bar end link joints may wear and cause a knocking noise over bumps. Loose or warn links should be replaced to correct this type of noise.

I feel the build quality is very high. However, if you care more about reliability than handling, comfort and a smooth drive train. Look at a lexus.
WORST Mercedes-Benz ever made! This car has cost me thousands of dollars in repairs and my extended warranty has paid out more than I paid for the car to actually fix items! I have been to the dealership 15 times in 2.5 years in which 4 of those times were for the same problem that has yet to be corrected. I filed multiple complaints with the National Highway Traffic Safety Administration (NHTSA) so if anyone else has major issues/problems, please file a complaint.
