2009 Mercedes-Benz C 2.1L Diesel · LS59 ECV

The most recent MOT, carried out on 17 October 2025, was passed but recorded an advisory that the near‑side rear tyre is approaching the legal tread limit and is worn on the edge. Over the last six years the vehicle has accumulated a steady stream of advisories – tyre wear on all four corners, progressive brake‑disc and pad thinning, a developing play in the off‑side front lower suspension arm ball joint and reduced parking‑brake effort. While none of these items have yet caused a failure, the pattern shows a gradual accumulation of wear rather than an improvement, indicating that routine maintenance has kept the car roadworthy but that several components are now approaching the end of their service life. At 169 838 mi the car averages just under 10 000 mi per annum over its 17‑year life, a usage rate that sits comfortably within the typical UK range for a vehicle of this age. There are no obvious gaps in the recorded mileage that would suggest prolonged periods of standing, nor any spikes that would point to unusually aggressive use. Consequently the wear observed on the tyres, brakes and suspension is consistent with normal calendar and mileage‑related degradation rather than the result of extreme loading or high‑speed abuse. A prospective buyer should give particular attention to the tyre condition; the front and rear tyres have repeatedly been flagged as close to the legal minimum and as showing edge wear, which often signals mis‑alignment, incorrect tyre pressure or worn suspension geometry. Check the tyre sidewalls for cracking, dry rot or bulges, and verify that the tread depth exceeds 1.6 mm on all corners. During a test drive listen for any wandering or pulling to one side, which would corroborate a suspension or alignment issue, and feel for vibrations that may indicate a warped or severely pitted brake disc. Inspect the front lower ball joint for any clunk or looseness when the steering wheel is rocked at a standstill, and examine the rear parking‑brake mechanism for slack or a need for adjustment, as the MOT notes reduced effort. The brake discs and pads have been flagged repeatedly; have the discs measured for thickness and surface condition, and consider a full brake service – disc resurfacing or replacement and pad renewal – before the discs become dangerously thin. Given the vehicle’s age, also assess items that deteriorate with time irrespective of mileage. Examine the battery terminals for corrosion and test the charge holding capacity, as a 17‑year‑old battery is likely nearing the end of its service life. Look for signs of corrosion on the chassis, particularly around the wheel arches and under the rear suspension, which can affect steering and suspension bushings. Verify that the service history includes regular oil, coolant and brake‑fluid changes; fluid should be clear and at the correct level, with any dark or contaminated fluid replaced as part of a preventative service. Finally, confirm that the exhaust system is free of cracks or excessive rust, and that all seat‑belt pretensioners and airbags have been inspected, especially given the 2018 advisory about a child‑seat obstructing belt inspection. Addressing these points will give a clear picture of any imminent maintenance and help the buyer budget for the next phase of ownership.
