2018 Mercedes-Benz A-Class 1.5L Diesel · M155 ABA

A largely clean MOT record defines this 2018 Mercedes-Benz A-Class, with five consecutive passes and only the most recent test on 27 June 2026 introducing any recorded defects. The vehicle passed on that occasion with a nearside rear tyre advisory for being worn close to the legal limit and on its edge, alongside a minor notice for a severely deteriorated dust cover on the nearside front anti-roll bar linkage ball joint. The four prior tests in 2022, 2023, 2024, and 2025 returned no advisories whatsoever, indicating that the only emerging concerns are very recent and confined to wear items rather than structural or safety-critical failures. There is no history of corrosion, brake or exhaust failures, suspension component rejections, or lighting defects across the entire testing period, which points to a stable and well-maintained roadworthiness profile. The recorded mileage of 70,489 miles over an eight-year lifespan equates to an annual accumulation of roughly 8,811 miles, which is broadly consistent with typical private and commuter usage for a vehicle of this age. There are no significant gaps in the MOT testing record and no evidence of long periods off the road, meaning the vehicle has seen regular use throughout its life and components have been subjected to normal operational wear rather than the risks associated with prolonged standing. This kind of steady, average-mileage usage generally supports consistent warm-up cycles for the engine and drivetrain, regular cycling of brake and suspension components, and reduces the likelihood of seized calipers, perished rubber seals, or degraded tyres from inactivity. The mileage progression between tests appears measured and consistent, with no sudden drops or unexplained reductions that might raise concerns. For a prospective purchaser, the priority items raised at the most recent test deserve focused attention on a physical inspection and test drive. The nearside rear tyre flagged as worn close to the legal limit and on its edge will almost certainly require replacement, and it is worth inspecting the other three tyres for uneven wear patterns, as edge wear on a single axle can indicate alignment issues, incorrect camber, or worn suspension bushes that may have developed since the test. A test drive should include careful observation of the nearside front suspension, listening for any clonks or knocking from the anti-roll bar area over speed humps and rough surfaces, and feeling for vagueness or rattle through the steering, as the deteriorated ball joint dust cover noted as a minor defect will allow dirt and moisture ingress and could progress to a failing joint if not addressed. The condition of the wider anti-roll bar drop links and bushes should also be visually checked for play or perished rubber. Beyond the flagged items, a thorough pre-purchase evaluation should confirm that the recent advisory and minor defects have been rectified, particularly a replacement tyre and inspection or renewal of the anti-roll bar linkage. A road test over varied surfaces should pay particular attention to brake pedal feel, looking for any pulling to one side, judder under heavy braking, or binding that could indicate sticking calipers, as no brake-related advisories have been recorded to date and any new symptoms would warrant investigation. Steering should be checked for straight-line stability and absence of vibration, and the underside should be examined for any early signs of corrosion on subframe, brake lines, and suspension arms, given that the vehicle is now eight years old and entering the period where structural advisories can begin to appear on Mercedes-Benz models of this generation. Given the otherwise unblemilled MOT history and the modest, consistent mileage, this A-Class presents a fundamentally sound platform, with only the routine, age-appropriate wear items currently requiring attention.
