2007 Mercedes-Benz CLK 1.8L Petrol · A3 KFL

A clear pattern of front suspension wear dominates the mechanical history of this 2007 Mercedes-Benz CLK, with the most recent test on 4 March 2026 recording a pass only after a failed attempt two days earlier that flagged both nearside and offside front suspension arm ball joints as excessively worn along with a perished offside front anti-roll bar linkage dust cover. Front suspension ball joint play has been an escalating concern across multiple tests: an advisory was recorded in March 2024 on the rear arm and again in March 2025 on the offside front, before progressing to major failure items on both sides in March 2026. A track rod end ball joint with excessive play also contributed to a March 2023 failure, reinforcing that the front steering and suspension geometry has been a recurring weak point rather than an isolated incident. With only six tests recorded across the vehicle's nineteen-year life and three of those producing failures or refusal notices, the roadworthiness record cannot be characterised as strong. The recorded odometer of 62,509 miles against roughly nineteen years of age equates to an average accumulation of around 3,290 miles annually, which is notably low and raises the possibility of extended periods of inactivity rather than consistent light use. The MOT testing pattern itself shows significant gaps, with no recorded tests between March 2010 and March 2022, indicating the vehicle was either off the public road, exempt, or untested for at least twelve consecutive years. Such prolonged standing typically accelerates deterioration of rubber components, brake discs and pads through surface corrosion, flexible brake hoses through internal degradation, and underbody sealing through lack of protective washing. The rear brake pad advisory from 2025 and the corroded rear brake pipe advisory from 2024 are consistent with this kind of low-use, stationary-pattern wear. For a prospective buyer, the immediate priority is a physical inspection of the front suspension now that both lower arm ball joints have just been replaced or repaired to pass the 2026 test. Listen for clonks or knocking from the front end over uneven surfaces, particularly over speed bumps and cat's eyes, and feel for vagueness or imprecise turn-in response through the steering wheel which would suggest the new components have not been correctly set or that additional wear has developed. Inspect the anti-roll bar linkage boots for fresh splits or grease contamination, and check that the dust covers are fully seated as the previous failure noted dirt ingress on the offside side. Carry out a hard left and right lock manoeuvre in a quiet car park to expose any binding or knocking that straight-line driving would mask. The brake system also warrants close attention given the 2024 advisory regarding a corroded rear brake pipe and the 2025 advisory on thin rear pads. Inspect the underbody, particularly along the rear brake lines and any under-sealed areas referenced in the 2026 advisories, for fresh underseal applied over corrosion rather than properly treated metal, as the recent advisories suggest this region has been flagged repeatedly. On the road, test the rear brake feel for a soft pedal or excessive travel which could indicate a seized rear caliper from prolonged standing, and verify that the handbrake holds on an incline without excessive ratchet travel. The exhaust mounting noted as defective in 2025 should be checked for excessive movement or rattling on start-up from cold, and confirm that the previously flagged windscreen washer system now delivers an adequate spray across the full screen area, as a repeat failure here would be straightforward to identify during a basic functional check.
