2010 Mercedes-Benz C 1.8L Petrol · CP10 CWD

A persistent pattern of tyre sidewall deterioration and lighting electrical faults runs through the MOT history of this 2010 Mercedes-Benz C-Class, with a recent test pass on 30 May 2023 continuing that trend. Across multiple inspections, all four tyre positions have been flagged at various points for cuts, cracking or perishing on the sidewalls, including an entry on the most recent test for a nearside front cut not deep enough to reach the ply or cords. Lighting defects have appeared repeatedly, with the central high-level stop lamp showing partial function failures in 2021, 2022 and at the failed 2022 retest, alongside an offside stop lamp failure on white-light emission and lens defect in February 2019. The 2022-05-20 retest also produced a Major failure for insufficient front washer fluid, suggesting either a neglected washer system or a possible underlying leak in the reservoir, pump or hose connections. The overall defect profile points to ageing exterior trim, deteriorating rubber components and recurring minor electrical gremlins rather than any single catastrophic mechanical failure. With an average of roughly 5,231 recorded miles per year over sixteen years, this vehicle sits at the lower end of the usage spectrum, and the gap between the February 2019 test and the May 2020 test, followed by consistent annual testing thereafter, suggests the car may have seen periods of reduced use before settling into a steadier pattern. Lower annual mileage of this nature typically preserves internal engine and drivetrain components but accelerates external degradation, particularly of rubber seals, suspension bushes, brake discs and tyre sidewalls due to cold starts, short journeys and prolonged stationary periods. The 2018 advisory for front brake disc wear and pitting is consistent with a vehicle that has accumulated standing time, as corrosion and surface pitting develop rapidly on discs that are not regularly heated through sustained braking. The wheel bearing play advisory from 2022 further supports a usage profile where suspension and hub components have aged in situ rather than wearing through high-mileage use. A prospective buyer should treat the tyre findings as a priority inspection point, as sidewall cracking across multiple positions on a sixteen-year-old vehicle raises legitimate concerns about overall rubber condition. A close physical examination of all four tyres is warranted, paying particular attention to sidewall flexibility, the depth of any cuts and the presence of perishing lines radiating from the bead area. Brake pedal feel during a test drive should be assessed for judder or pulsation, which would confirm whether the front discs noted in 2018 have continued to deteriorate or have been replaced, and a visual check of disc edges for heavy lipping or corrosion should be carried out with the wheels removed. The slight wheel bearing play flagged on both sides in 2022 is borderline, and any progression should be evaluated by gently rocking the wheels at the front and listening for rumble or humming that changes with vehicle speed, particularly during cornering, as worn front wheel bearings on this model typically present as a drone that alters with steering input. The electrical faults documented across three consecutive test years warrant functional checks of the entire rear lighting cluster before purchase, including the high-level stop lamp, position lamps and number plate illumination, as partial LED failures on Mercedes-Benz C-Class vehicles of this era often indicate water ingress into the lamp units or failing solder joints on the multi-source LED boards rather than simple bulb replacement. A thorough under-bonnet inspection is also advisable given the washer failure, with particular attention to the washer fluid reservoir, pump, hose routing across the bonnet hinge area and the wiper linkage for any seepage, and a road test with the washer operated repeatedly to confirm consistent spray at both front and rear jets. Suspension condition should be evaluated by pushing down firmly on each corner and listening for any knocking or clonking over uneven surfaces, focusing on the front control arm bushes, anti-roll bar drop links and rear subframe mounting points, which are known corrosion areas on this chassis and would not necessarily have been fully inspectable during the MOT due to undertray shielding. A structural inspection from beneath the vehicle, ideally with it raised on a ramp, is strongly advised to confirm the integrity of the rear axle carrier, spring perches and brake pipe runs before committing to purchase.
