2016 Mercedes-Benz C 2.1L Diesel · LS66 DUU

A pattern of tyre tread depletion and brake wear dominates the mechanical narrative of this 2016 Mercedes‑Benz C, underscored by a recent MOT failure that recorded a dangerous near‑side rear tyre depth, a near‑side rear pad thickness below the legal minimum and an inoperative engine MIL indicator, while the latest June 2026 test only returned a pass with an advisory on front tyre wear. Earlier in 2025 the car also failed on two tyre tread depths and was flagged for thin rear pads, and the same period saw recurring advisories for front brake disc wear and lower front suspension arm bush wear, suggesting that tyre and brake consumables have been a persistent concern. At 114,258 miles the vehicle averages roughly 11,400 miles per annum, a mileage rate that sits comfortably within typical usage for a ten‑year‑old executive saloon. The steady accumulation of miles, without any large gaps in MOT testing, indicates regular road use rather than prolonged storage, meaning that wear items such as tyres, brake pads, discs and suspension components are likely to have experienced proportional ageing. The mileage level also raises expectations that consumables will be approaching the end of their service lives, especially given the documented brake and tyre deficiencies. Prospective buyers should give the tyre condition immediate attention: verify that all four tread depths exceed 1.6 mm, look for uneven wear patterns that could hint at mis‑alignment or worn suspension bushings, and feel for any sidewall damage or vibration when cruising. The brake system warrants a thorough inspection – confirm that front disc thickness is within safe limits, rear pads are above the 1.5 mm threshold, and that the hydraulic circuit delivers consistent pedal travel without judder; any pulsation or sponginess could indicate warped discs or air in the lines. The lower front suspension arm pin or bush, previously noted as worn, should be checked for excess play or knocking over bumps, as excessive movement can accelerate tyre wear and affect handling. Finally, the engine MIL fault flagged as a major failure must be diagnosed with a proper scan tool to identify the specific sensor or emission component at fault before the vehicle is relied upon for regular driving. A prudent next step is to have a qualified technician perform a full brake service, replace any tyres that fail the tread check, and address the lower front suspension arm bush if movement is detectable. An engine diagnostic should be run to clear the MIL warning and rectify any underlying fault, which may involve sensor replacement or emissions system repair. Budgeting for these items will bring the car back to a condition where it can meet future MOT requirements without recurring advisories or dangerous failures.
