2017 Mercedes-Benz A-Class 2.1L Diesel · 7 OMY

The vehicle’s most recent MOT test on 27 March 2026, at 103,247 miles, confirms it remains roadworthy but with notable patterns of wear that demand closer scrutiny. While the current pass indicates no immediate failings, the history reveals a concerning trend in brake and wheel integrity. The 2026 test flagged all four brake discs as worn, pitted, or scored—though not critically weakened—which suggests either deferred maintenance or a lack of proactive brake servicing. The 2025 test further exposed a distorted near-side front wheel, nails embedded in tyres, and tyres worn close to the legal limit, all of which imply inconsistent upkeep. The 2024 failure for fractured front wheels and repeated nail punctures in tyres underscores a structural vulnerability, particularly in the wheel assemblies, which should not be overlooked. The mileage progression of approximately 11,472 miles annually aligns with typical usage for a vehicle of this age, though the gap between the 2023 and 2024 tests—spanning 18,000 miles—is unusually long and raises questions about interim maintenance. The 2024 failure at 66,649 miles, just two days before the subsequent pass at 66,661 miles, suggests either a rushed repair or a temporary fix rather than a comprehensive resolution. No tests are recorded between 2024 and 2025, a period covering 18,000 miles, which is suspicious given the wheel and tyre issues that emerged. This irregularity warrants verification of whether critical components were addressed between tests. A prospective buyer should prioritise an independent inspection of the wheel assemblies, particularly the near-side front, given the 2024 fractures and 2025 distortion. The brake discs, while not yet at failure, show accelerated wear that may indicate binding calipers, uneven pad replacement, or inadequate cooling—all of which could lead to premature failure. The tyres, with nails embedded and tread worn to the legal limit in 2025, suggest either neglect or repeated damage; a thorough check for hidden punctures, uneven wear, or substandard compounds is essential. Suspension bushes and coil springs should also be examined for deterioration, as the wheel fractures imply potential stress on the mounting points. Finally, the absence of emissions or structural advisories in recent tests does not guarantee their absence, so a visual inspection for corrosion in wheel arches, subframes, and sills is advisable.
