2015 Mercedes-Benz C 2.1L Diesel · LS08 JSS

The most recent MOT on 5 June 2026 was passed, but it carried advisories that the nearside and off‑side rear tyres are worn close to the legal limit and showing edge wear. Over the past six years the vehicle has moved from clean passes in 2024 and 2023 to two major failures – the front lower suspension arm ball joints in 2021 and the front lower suspension arm ball joints again in 2025 – each accompanied by advisory notes on rear sub‑frame corrosion and thin front brake pads. The pattern shows a deterioration rather than an improvement, with recurring wear on suspension joints, brake components and tyre tread, indicating that the underlying wear items have not been fully addressed. At 157,279 mi the car averages roughly 14,300 mi per year, considerably above the UK average for a vehicle of its age. This higher annual mileage accelerates wear on consumables such as tyres, brakes, suspension bushings and joints, and it places additional stress on the drivetrain and engine oil life. The mileage also suggests the car has seen regular use rather than long periods of standing, which means corrosion from exposure is less likely to be severe but the cumulative mechanical load is a factor in the recurring suspension joint failures. A prospective buyer should give the front lower suspension arms a thorough inspection. Look for any play when the wheel is rocked side‑to‑side, listen for clunking or knocking over bumps, and check the condition of the ball joints and the surrounding rubber bushes for cracks or excessive movement. The rear sub‑frame advisory indicates corrosion at mounting points; a visual examination for rust, especially around the rear suspension mounting brackets and the rear cross‑member, is essential, and any signs of flaking or pitting should be followed up with a structural assessment. Brake wear is also a concern: the rear discs were noted as pitted in 2022 and the front pads were thin in 2025, so the buyer should test for brake pedal feel, any pulsation or shudder when applying the brakes, and inspect the discs for scoring and the pads for remaining thickness. The rear tyres are already close to the legal tread limit, so measuring tread depth on all four wheels and checking for sidewall cracking or dry rot is mandatory, with the expectation that at least the rear set will need replacement imminently. Beyond the specific MOT items, the car’s age warrants a check of time‑related items. Verify the condition of the 12 V battery, looking for corrosion on terminals and testing voltage under load; a battery older than five years may need replacement. Examine all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – for correct colour, level and any signs of contamination, as fluids degrade with time even if mileage is moderate. Finally, confirm that the service book contains regular oil changes and that any major services (e.g., timing‑chain or suspension component replacements) have been recorded; absent evidence, budgeting for a comprehensive service, including fresh oil, filter, coolant flush, and a full brake and suspension overhaul, would be prudent before committing to purchase.
