Mercedes-Benz CLK320 Problems
RepairPal has identified the most common problems with the Mercedes-Benz CLK320 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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 crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.
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.
The instrument cluster display may lose pixels and need replacement. However, if the back lighting bulbs for the odometer display in the center of the cluster burn out, they can be replaced.
Cup holders in the dash are known to break requiring repair or replacement.
Ball joints can wear out prematurely, causing wear in the tires.
The heating, ventilation and AC (HVAC) heater box is susceptible to mildew buildup. This can result in a musty odor from the HVAC system, most noticeable when the system is first turned on.
