2006 Mercedes-Benz CLK350 Problems
Rough Shifting of Automatic Transmission
Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.
HVAC Oder Due to Mildew in Heater Box
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.
Check Engine Light Due to Faulty Camshaft Adjuster Solenoid
The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.
"Crank no Start" Due to Failed Crankshaft Position Sensor
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. Communicating these specific symptoms to your technician can save diagnostic time.
ABS Modulator Failure Due to Dirty Brake Fluid
The anti-lock brake system (ABS) modulator assembly may fail due to dirty brake fluid. Our technicians recommend a complete brake system flush every two years in order to help prevent this problem.
Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration
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.
Knocking Noise Over Bumps Due to Worn Sway Bar Link Joints
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.
Hold down nut for front strut may bacome loose
Brake Pads & Rotors May Wear After 20,000 Miles
As a way to increase braking performance, the brake pads and rotors are make of a softer material and may be in need of replacement after approximately 20,000 miles; owners should be vigilant about getting their brakes checked.
Cup Holders in Dash May Break
Cup holders in the dash are known to break requiring repair or replacement.
Convertible Models may Deploy the Roll Bar When Driving Over Large Bumps
Going over large bumps in convertible models may cause the roll bar to deploy, rendering the roof inoperative. Special tools are generally required to return the roll bar to its stowed position.
Ball joints may wear and cause tire wear
Ball joints can wear out prematurely, causing wear in the tires.
Computer Control Modules (Seats, Doors, CD Changer, Brake Lamp Switch) May Fail
Computer control modules for the seats and doors, the CD changer, and the brake lamp switch tend to fail.
Alignment &Tire Wear Issue and/or Clunk or Thud From Front Suspension
Torque thrust bushings in the front suspension may crack and leak oil, this causes steering alignment problems and excessive tire wear. Another symptom of a worn bushing is a clunk or thud noted when turning, on hard acceleration, or hard braking.
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.
