2010 Mercedes-Benz CLS 3.0L Diesel · BU10 YVT

A persistent tyre‑wear advisory dominates the MOT history, with all four tyres flagged as close to the legal limit on several occasions and a failure recorded in August 2022 for the same issue. The most recent test in August 2023 passed without defects, suggesting the current set of tyres met the minimum tread depth, but the pattern indicates the car is consistently operating on the edge of tyre life and will likely require a full replacement soon. At 148,158 miles over 16 years the average annual mileage is roughly 9,260 mi, which sits squarely within normal private‑car usage for a vehicle of this age. There are no significant gaps in the MOT chronology, implying the car has been driven regularly rather than sitting idle for long periods. This steady mileage translates to moderate wear on consumables such as tyres, brakes and suspension components, but does not alone signal accelerated degradation. The tyre condition should be the first focus of a test drive. Feel for any vibration through the steering wheel at 50–70 mph, listen for a humming or growling noise that may indicate uneven tread or a developing internal fault, and inspect the sidewalls for cuts or bulges, especially on the off‑side front where a cut was noted in 2021. Verify that the new tyres (if fitted) have even wear across the width and that the tyre pressures hold steady. The oil‑leak advisory recorded in 2022 remains unresolved; look for fresh oil spots on the garage floor, a low oil level on the dipstick, and listen for a faint dripping sound from the engine bay. Any sudden drop in oil pressure or a warning light on the dash would warrant immediate investigation of the valve‑cover gasket, oil filter housing or oil pan. Older advisories from 2017 flagged slight play in the off‑side front wheel bearing and some play in the nearside steering rack. During a low‑speed drive, test for a faint knocking or grinding from the front wheel when applying the brakes, and check that the steering feels tight with no excessive free play or a “dead” feel when turning the wheel fully left or right. A clunk or shudder when passing a bump may also point to worn suspension bushes or deteriorating steering linkages. A thorough pre‑purchase inspection should confirm the condition of these bearings, the steering rack bushings and the overall suspension geometry, as remedial work on these items can become costly if they have progressed since the last MOT.
