2008 Mercedes-Benz C 2.1L Diesel · LP08 OKS

The vehicle most recently presented for MOT testing on 19 September 2025 and was awarded a Pass, with two advisories recorded against the nearside and offside rear tyres for slight damage, cracking or perishing. Looking across the five most recent test results, the overall maintenance trajectory is broadly stable rather than deteriorating, although the volume of advisory items has trended upward in 2024 and 2025 compared with the relatively clean 2023 pass. The 2024 test in particular carried forward several advisories that reappear in the historical pattern, suggesting that while the vehicle remains roadworthy, a number of wear-related items are progressing slowly and would benefit from closer attention at the next service interval. No failures, refusals, or dangerous defects have been recorded across the available history, which is reassuring for a vehicle of this age. With 48,240 miles recorded over approximately eighteen years, this equates to an annual average of around 2,680 miles, which is notably low for any passenger vehicle and especially for a Mercedes-Benz C-Class that would typically be expected to cover considerably more. This low-mileage profile strongly suggests significant periods of standing or only occasional use, and from a mechanical standpoint, prolonged inactivity is rarely less wearing than regular driving. Standing vehicles are particularly susceptible to brake disc surface corrosion, caliper piston seizure, tyre sidewall perishing, fluid degradation, and 12V battery sulphation, all of which can develop independently of odometer readings. The user should also be aware that the recorded mileage gaps make it difficult to confirm whether the vehicle has been serviced on a calendar basis rather than purely on mileage, which is critical for a car now approaching two decades old. The recurring advisories on the rear tyres for cracking and perishing across both 2024 and 2025 warrant particular attention, as rubber compounds deteriorate with age and UV exposure irrespective of tread depth, and perished tyres can fail unexpectedly under load or at speed. On a physical inspection, all four tyres should be examined closely for sidewall cracking, particularly in the flex zone between the tread and the wheel rim, and the production date code on the sidewall should be checked, as tyres older than six years are generally considered past their safe service life even with adequate tread. The 2024 advisory regarding front suspension arm pin or bush wear, described as splitting, is consistent with the natural degradation of rubber bushes on a vehicle of this vintage and is a known weak point on Mercedes-Benz W204 C-Class models. A test drive should include driving over uneven surfaces and speed bumps while listening for clonking or knocking from the front suspension, and the buyer should also feel for any vague wandering or imprecise steering response that could indicate advanced bush wear. The advisories relating to front brake disc wear and the corrosion of brake pipes and hose ferrules, noted in both 2022 and 2024, point to an ongoing corrosion picture on the underbody brake system, which is typical of older vehicles exposed to winter road salt. The brake pipe advisories specifically note that the corrosion is covered in grease or other material, which is a common attempt to pass a test while masking underlying surface corrosion, and the buyer should be cautious of this. A thorough inspection with the vehicle on a ramp is advisable to confirm the structural integrity of the brake lines, particularly along their length and at unions, and to assess whether the corrosion is purely superficial or has begun to compromise the metal. The front brake discs, flagged as worn in both 2022 and 2024, should be measured for remaining thickness against the minimum stamped specification, as they will likely require replacement in the near term. Beyond the recorded advisories, given the low mileage and age, the buyer should also verify the condition and age of the 12V battery, the freshness of the engine coolant, brake fluid, and automatic transmission fluid if applicable, the operation of the handbrake mechanism which can seize from standing, and the condition of all rubber gaiters and seals for perishing. A compression or leak-down test on the engine would also be prudent to confirm internal health given the long periods of low use.
