2016 Mercedes-Benz A-Class 2.1L Diesel · SK16 AAU

The Mercedes-Benz A-Class has maintained a passing MOT status in its most recent test on 21 September 2024 at 133,241 miles , though the trend reveals persistent issues that suggest deferred maintenance rather than mechanical failure. The tester consistently flagged front and rear brake discs as worn, pitted, or scored across three consecutive tests—first appearing in October 2023 at 124,398 miles and recurring through to the latest inspection. This indicates a pattern of progressive brake wear , likely accelerated by uneven braking habits or suboptimal disc resurfacing/replacement. Tyres also show a worrying trend: the nearside front and both rear tyres were recorded as worn close to the legal limit or unevenly worn in 2022, 2023, and 2024 , with no evidence of rotation or replacement between tests. The absence of defects in September 2021 at 104,109 miles suggests these issues developed post-2021, possibly due to a change in ownership or neglect of routine servicing. The vehicle’s mileage accumulation— 133,241 miles in under 10 years —is high for its age, averaging around 13,324 miles annually , which strains consumables like brakes and tyres beyond typical expectations. The 8,584-mile jump between October 2022 (116,717 miles) and October 2023 (124,398 miles) suggests either intensive use or a period of inactivity followed by rapid mileage buildup. The most recent 8,843-mile interval between October 2023 and September 2024 aligns with the annual testing cycle, but the lack of progress in addressing tyre and brake wear implies either cost-cutting by previous owners or indifference to basic maintenance . The absence of structural defects or advisories on suspension components (e.g., bushes, coil springs) in any test is a positive sign, though this does not preclude hidden wear in less frequently inspected areas. For a prospective buyer, in-person inspection must prioritise the brake system , particularly the condition of the discs, calipers, and pads —given the repeated MOT failures, binding or uneven braking could be present. The tyres require immediate assessment: uneven wear patterns may indicate alignment issues, suspension faults, or prolonged underinflation , all of which could lead to premature failure. While the MOT history shows no signs of corrosion, structural damage, or exhaust emissions failures , a closer look at the suspension bushes, ball joints, and steering rack is advisable, as these are less frequently tested but critical for handling. The rear brakes should also be scrutinised for excessive play or noise, as the MOT record does not rule out worn brake hardware or seized components . Given the vehicle’s age and mileage, a full brake overhaul and tyre replacement would be prudent investments to restore reliability.
