2008 Mercedes-Benz C 2.1L Diesel · KN58 SDX

A recurring theme of front‑suspension wear and brake‑pad depletion runs through the MOT record, with the latest test in May 2026 still passing but noting slight play in the nearside front lower suspension arm ball joint, corrosion on the rear sub‑frame and a rear tyre approaching the legal limit. Earlier in 2021 the car failed dangerously due to front brake pads under 1.5 mm, and in 2020 it failed for rear brake pads in the same condition, both accompanied by advisories on disc wear. The pattern shows that while the vehicle has cleared recent inspections, the suspension and braking components have required repeated attention. At 193,089 mi recorded over an 18‑year lifespan the average annual mileage works out to roughly 10,700 mi, which sits within normal UK usage for a vehicle of this age. MOTs have been logged annually with no prolonged gaps, indicating the car has been on the road consistently rather than sitting idle for extended periods. The mileage level suggests that consumables such as bushings, ball joints, brake pads and tyres are likely to be in the later stages of their service life and will need close inspection or replacement in the near term. For the suspension, the advisory on slight play in the nearside front lower arm ball joint should be verified by checking for looseness when the steering wheel is rocked at a standstill and listening for clunking over bumps. The off‑side rear tyre being close to the legal limit warrants a tread‑depth check on all four tyres; uneven wear could point to the noted ball‑joint play or alignment drift. The rear sub‑frame corrosion, although not deemed structurally weakened, should be inspected for any flaking, pitting or rust‑induced cracks, especially around mounting points, and a test‑drive should include listening for creaks when cornering or under load. Brake wear demands immediate attention: the dangerous failures recorded in 2020 and 2021 indicate that both front and rear pads were below the minimum thickness at those dates, and the accompanying disc advisories suggest surface pitting. A buyer should measure current pad thickness, feel for pedal travel and any pulsation, and listen for squeal or grinding under moderate braking. Given the history, replacement of pads on both axles, and likely resurfacing or replacement of the discs, is prudent before committing to the purchase. Additionally, confirm that the tyre tread on the off‑side rear wheel meets legal depth and that the remaining tyres are of comparable condition to avoid premature replacement.
