2016 Mercedes-Benz A-Class 1.5L Diesel · CE66 WTP

A pattern of suspension and brake wear has emerged across the MOT history of this 2016 Mercedes-Benz A-Class, with two separate failures flagging serious structural and mechanical defects within the last three years. The most recent test on 23 September 2025 was a pass, but it was accompanied by three advisories covering edge-worn front tyres, pitted rear brake discs, and an edge-worn nearside rear tyre, suggesting that the consumables on this vehicle are reaching the end of their useful life simultaneously. More concerning is the failure recorded on 27 October 2023, which identified an excessively worn offside front suspension arm ball joint and a fractured offside rear coil spring, both classified as Major defects. A further failure on 18 September 2024 cited an insecure exhaust silencer as a Major item, alongside advisories for wearing front brake pads and a defective rear exhaust mounting. The overall trend is therefore one of escalating mechanical concern, with repeated issues affecting the suspension, braking, and exhaust systems across consecutive test cycles. The recorded mileage of 108,965 miles across approximately ten years equates to an annual accumulation of around 10,900 miles, which is broadly typical for a vehicle of this age. There are no significant gaps in the testing history, with annual MOT records present from 2020 through 2025, and the mileage progression appears consistent throughout. For a Mercedes-Benz A-Class covering this kind of annual distance, the mechanical expectation is steady wear on suspension components, braking hardware, tyres, and exhaust mountings, all of which are corroborated by the advisory and failure entries in the record. The absence of advisories in 2020, 2021, 2023, and 2024 indicates that the wear pattern is not constant, with components reaching serviceable limits in particular cycles rather than degrading uniformly. The failures in late 2023 and 2024 align with the typical wear curve for a Mercedes of this age and mileage, particularly where original suspension components and exhaust rubber mountings begin to deteriorate. A prospective buyer should focus the pre-purchase inspection on the suspension and braking components flagged in the recent MOT history. The fractured rear coil spring and worn front ball joint recorded in 2023 are particularly significant; on a test drive, listen for clonking or knocking noises from the front suspension over speed bumps and uneven surfaces, which would indicate worn bushes or failing ball joints. The offside rear suspension should also be checked for any sagging or uneven ride height, as a weakened or replaced coil spring can occasionally be accompanied by shock absorber fatigue. On the braking side, the pitted rear discs noted in 2025 and the thin front pads flagged in 2024 suggest that a full brake refresh may now be due. On the road, test for pulling to one side under braking, any vibration through the pedal, and a spongy or inconsistent pedal feel, as the advisory for fluctuating offside front service brake in 2022 hints at potential caliper or guide pin issues that may have resurfaced. The exhaust system warrants close physical inspection beneath the vehicle, given the Major failure for an insecure silencer in 2024 and the advisory for a defective rear mounting. With the engine running, listen for any exhaust blowing, ticking, or metallic rattling that would suggest a loose heat shield or worn mounting rubber. Inspect all tyres carefully for uneven shoulder wear, as both the 2022 and 2025 tests recorded tyres worn close to the legal limit on their edges, which can point to suspension geometry misalignment, often a consequence of worn bushes or droplinks on a high-mileage Mercedes. Finally, request evidence that the 2023 suspension repairs were completed using quality components, as a ball joint replacement on this platform typically requires accompanying control arm renewal, and any shortcut repairs could compromise long-term reliability.
