2018 Mercedes-Benz C 3.0L Petrol · D9 PTM

Accumulating a concentration of urgent safety defects during its August 2026 examination, culminating in a dangerous failure for a nearside front tyre below the legal limit alongside worn brake components, punctuates an otherwise routine MOT history for this 2018 Mercedes-Benz C-Class. Although the vehicle subsequently secured a pass on September 2nd, 2026, at 68,429 miles following immediate rectification, the surrounding advisories reveal an ongoing pattern of heavy tyre wear across multiple axles and recurring suspension dampener misting. Specifically, both rear tyres exhibit perishing and cracking, the offside front tyre features uneven edge wear, and light oil misting is noted on the offside front shock absorber, indicating that the vehicle requires closer mechanical scrutiny than a strictly pass-or-fail record might initially suggest. The odometer reading of 68,429 miles amassed over roughly eight years yields an average annual accumulation of approximately 8,554 miles, placing this Mercedes-Benz squarely within typical usage parameters for its age. This steady operational cadence shows no evidence of extended stationary periods or abnormal mileage surges, meaning the mechanical wear observed across the drivetrain and chassis components is consistent with regular, everyday motoring rather than commercial over-utilization or prolonged structural dormancy. When conducting a test drive, prospective buyers must pay strict attention to the front and rear axles, listening closely for any knocking noises, excessive body roll, or uncharacteristic float over uneven road surfaces that would signal worsening degradation of the shock absorbers exhibiting oil misting. Furthermore, drivers should inspect the steering feel for any vibration, tramlining, or pulling to one side, which can be exacerbated by the aggressive inner-edge tyre wear patterns frequently flagged on these wide-profile setups. A thorough physical check of the remaining tread depth and sidewall condition on all four corners is essential, alongside verifying that the front brake discs and pads noted as wearing thin during the late-August failure have indeed been replaced with quality components. Finally, verify that the insecure rear registration plate noted on the final test certificate has been properly resecured to prevent rattling or detachment, and inspect the wheel alignment settings to address the root cause of the recurring uneven tyre wear. Ensuring that geometry checks are performed will protect any newly fitted tyres from premature shoulder wear, while a ramp inspection during a pre-purchase evaluation will confirm whether the shock absorber misting has progressed to active fluid leaking requiring immediate suspension replacement.
