Mercedes-Benz SLK320 Problems

Brakes	Due to the size and materials of the brakes on these vehicles, the brakes start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain). Brake fluid should be flushed every two years to prevent premature anti-lock brake system (ABS) failure.
Engine	Oil leaks from the PCV vent housings on the valve covers and inspection plates on the front of the engine are common. The rubber bond in the harmonic balancer can decay, which causes the balancer to move and work its way into the timing chain cover. If the balancer comes into contact with the timing cover while the engine is running, it will fracture and damage the timing case and potentially other surrounding parts. The harmonic balancer should be inspected at every service. Oil leaks from the oil level sensor are common. The crankshaft position sensors tend to 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. Communicating these specific symptoms to your technician can save diagnostic time.
Exhaust & Emissions	Bad spark plug wires and ignition coils can cause intermittent misfires (rough running); the Check Engine Light may illuminate. The mass air flow sensor tends to fail causing poor fuel economy and Check Engine light illumination. The engine air filter should be replaced when the mass air flow sensor is replaced; a dirty filter can allow debris to damage the new sensor.
Suspension & Steering	Irregular and premature tire wear can be caused by the lower control arm bushings cracking and causing excessive movement at the control arm pivot point. Ball joints can also wear out prematurely, causing similar tire wear symptoms. The tie rod ends, drag link, and idler arm in the linkage of the steering system can wear out. There is a steering dampening shock that will leak fluid when it goes bad.
Drive Train	A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential. High mileage or older vehicles develop leaks at the differential seals and cover; the whole unit needs to be resealed to repair the leaks. The wire connector on the transmission leaks 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 are required to fix the problem.
Electrical & Lights	Brake light switch failure can cause the ESP and BAS warnings to illuminate. CD changers in the trunk can fail. Position switches for the vario roof can fail, causing the roof to stop in the process of opening or closing.
Heating & Air Conditioning	The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not cycle on, the AC system will not blow cold air. If the AC compressor is stuck on, the air will be very cold at first, before warming up.
