Which Clk are you looking at?
Each Clk generation has its own weak spots. Pick the one you’re viewing to see what to check.
-
Suspension component corrosion and damage
Wear item C208, C209Mercedes CLK models show abnormally high rates of suspension component failure due to corrosion and structural damage. MOT data shows this model fails at 822.2x the national fleet average for suspension damage across all engine variants. The multi-link rear suspension uses steel components that are prone to corrosion, particularly the lower control arms and anti-roll bar links. Front suspension strut top mounts and lower ball joints also fail at elevated rates.
What to check: Inspect all visible suspension components for rust, cracking, or obvious damage with the car on level ground. Look specifically at the rear lower control arms and anti-roll bar links for corrosion or distortion. Check for any loose or missing bolts in the suspension mountings. Examine the rubber ...
-
Steering ball joint excessive wear
Wear item C208, C209CLK models suffer from premature wear of steering ball joints, with MOT failure rates 98x higher than the national average. The issue affects track rod ends and steering linkage components across all engine variants. Wear is accelerated by the car's weight distribution and the design of the steering geometry, particularly on higher-mileage examples.
What to check: Grasp each front wheel at 9 and 3 o'clock positions and attempt to rock it horizontally - any movement indicates worn ball joints. Inspect the rubber dust boots on visible steering components for splits or tears. Look under the car for any obvious play in the steering linkage.
-
Brake hose deterioration
Safety and MOT risk C208, C209CLK models show exceptionally high rates of flexible brake hose failure, with MOT data indicating 64x higher failure rates than the fleet average. The rubber brake hoses deteriorate and can become damaged, chafed, or twisted. This issue affects all variants and can occur at any mileage, including low-mileage examples.
What to check: Visually inspect all visible brake hoses for cracking, bulging, or chafing against other components. Check for any signs of brake fluid leakage around hose connections. Look for hoses that appear twisted or kinked. Examine where hoses pass near suspension components for contact damage.
-
Wheel bearing excessive play
Wear item C208, C209CLK models suffer from premature wheel bearing wear, with MOT failure rates 29x higher than the national fleet average. The issue affects both front and rear bearings and can occur at relatively low mileages. The bearings are integrated hub units that cannot be serviced and must be replaced as complete assemblies.
What to check: Jack up each wheel individually and grasp at 12 and 6 o'clock positions - any vertical movement indicates bearing wear. Spin each wheel by hand and listen for grinding or rumbling noises. Check for any obvious looseness when rocking the wheel.
-
Diesel particulate filter blockage
Wear item C209The 2.7 CDI and 3.0 CDI engines are particularly affected. Short journey patterns and urban driving prevent proper DPF regeneration, leading to progressive blockage and eventual failure.
What to check: Check if any DPF warning lights are illuminated on the dashboard. Ask the seller about recent long motorway journeys - lack of these indicates potential DPF issues. Check service history for any DPF-related repairs or forced regeneration procedures.
