Which Cl are you looking at?
Each Cl generation has its own weak spots. Pick the one you’re viewing to see what to check.
-
Subframe structural corrosion
Safety risk C215, C216The front and rear subframes carry the suspension mounting points and are critical structural components. 0L variants. The prescribed area around suspension mounting points is subject to strict MOT standards - any significant corrosion or inadequate repair in these zones results in immediate test failure and renders the vehicle unroadworthy until properly repaired.
What to check: Inspect the front subframe mounting points visible from under the bonnet for rust, particularly where the subframe bolts to the main body shell. Look under the rear of the car at the rear subframe mounting areas for obvious corrosion or previous welding repairs. Check for rust staining or flaking...
-
Air suspension system failure
Wear item C215, C216The Airmatic air suspension system uses air springs, height sensors, and a central compressor to provide adaptive ride height control. The system is standard on all CL models and suffers from multiple failure points including air spring membrane splits, compressor overheating, and height sensor drift. MOT data shows this model fails air suspension tests at 340 times the fleet average, making it one of the most problematic systems on any luxury car. Repair costs regularly exceed £3000 when multiple components fail simultaneously.
What to check: Walk around the car and check that it sits level - any visible lean to one corner suggests an air spring has lost pressure. Look under each corner for obvious air spring deflation or the car sitting directly on its bump stops. Listen for continuous air compressor running from the rear of the car ...
-
Front wheel bearing failure
Wear item C215, C216The front wheel bearings on CL models are integrated hub units that carry the considerable weight of the large luxury coupe body and cope with forces from the wide, low-profile tyres typically fitted. MOT data shows wheel bearing failure at 23 times the fleet average with a worsening trend, particularly affecting cars from 40,000 miles onwards. The bearings are sealed units that cannot be serviced and must be replaced complete with the hub assembly when they fail.
What to check: Jack up each front wheel in turn and grab the tyre at 12 and 6 o'clock positions. Rock it firmly - any movement indicates bearing wear. Spin the wheel by hand and listen for grinding, rumbling or clicking noises from the hub area. Check the wheel bolts are properly torqued - loose wheels accelera...
-
Brake line and hose deterioration
Safety and MOT risk C215, C216The brake hydraulic system uses steel brake pipes and flexible rubber hoses to connect the master cylinder to the calipers at each wheel. MOT data shows brake pipe corrosion at 5.4 times fleet average and flexible hose deterioration at 7 times fleet average, both with worsening trends. The complex brake system on CL models including ABS, ESP, and SBC (on some C215 models) places additional stress on hydraulic components through frequent pressure cycling.
What to check: Look under the car along the brake pipe runs for obvious corrosion, particularly where pipes pass through the body or near road salt spray areas. Examine the flexible brake hoses at each wheel for cracking, bulging, or chafing against suspension components. Check the brake fluid reservoir level a...
-
Suspension bush and joint wear
Wear item C215, C216The multi-link front and rear suspension systems use numerous rubber bushes and ball joints to locate the control arms and absorb road noise. The considerable weight of the CL body and aggressive alignment settings to suit wide tyres accelerate wear of these components. MOT data shows suspension component wear at 13.6 times the fleet average with a worsening trend, affecting all engine variants from moderate mileages onwards.
What to check: Look under the front of the car for obviously split or deteriorated rubber bushes on the lower control arms - they should be intact with no visible cracking. Check the anti-roll bar drop link rubbers for splits or missing sections. Examine the rear subframe mounting bushes if accessible - large t...

How do I check if a Mercedes Benz Cl has been written off?
Our check queries Experian’s insurance write-off database for Cat A, B, S and N markers. A Cat S or N Cl has been structurally or non-structurally damaged and repaired. This doesn’t mean it’s unsafe, but it affects resale value and some insurers won’t cover it. The check costs £7.49.
Can I check a Mercedes Benz Cl for free?

Is a Mercedes Benz Cl HPI check worth it?
HPI is one brand of car check. Our check uses the same Experian data covering finance, stolen, write-off and keeper history, plus MOT analysis and known Cl faults that HPI doesn’t include. At £7.49 it’s typically less than half the price of an HPI check.
