2015 Mercedes-Benz A-Class 1.6L Petrol · BU65 DFK

A clear pattern of front suspension and tyre wear advisories has emerged across the MOT history of this A-Class, with the May 2026 test on 08 May providing the most recent evidence of this trend. The 2026 pass still carried forward a Minor defect for the offside front anti-roll bar linkage ball joint dust cover being severely deteriorated, the same item that had caused the failure recorded just two days earlier on 06 May when the nearside cover was deemed to no longer prevent the ingress of dirt. The fact that this anti-roll bar component progressed from an Advisory level of wear to a Major defect within forty-eight hours demonstrates that the deterioration was at an advanced stage and that both sides of the front anti-roll bar linkage should be considered for imminent replacement. Tyre advisories have likewise been a recurring theme, with nearside and offside front tyres flagged as worn close to the legal limit on edge in both 2023 and 2026, while rear tyre sidewall cracking or perishing has appeared in 2020, 2021, 2025 and 2026, the latter on the offside rear. The recorded mileage of 62,177 miles against an eleven-year vehicle age equates to an annual accumulation of roughly 5,652 miles, which is notably below the typical mileage for a car of this vintage. The MOT record covers every year from 2020 through to 2026 with no testing gaps, indicating the vehicle has remained in continuous use throughout this period and has not been laid up for any extended absence from the road. While low annual mileage can reduce wear on high-cycle components such as the engine, clutch and braking surfaces, it does also bring the well-documented risk of standing-start degradation to rubber components, which aligns with the recurring tyre perishing advisories on this particular vehicle. The relatively modest mileage means that wear-related failures such as clutch slip, turbo failure or major engine oil consumption issues would not be expected at this stage, but the age of the car means that age-sensitive items including drive belts, coolant hoses, suspension bushes and corrosion protection remain the primary mechanical concerns. A prospective buyer should treat the front anti-roll bar linkage dust cover defect as the most pressing item to verify, as the 2026 Minor shows that replacement of both ball joint assemblies is now overdue. On a test drive, listen for clonking or rattling noises from the front suspension over speed humps, uneven road surfaces and during full-lock steering manoeuvres, and feel for any vagueness or shimmy through the steering wheel that would indicate the worn ball joints are no longer holding the anti-roll bar securely. Pay particular attention to the rear tyres for visible cracking of the sidewall rubber, as this has been flagged in four separate annual tests and suggests the rubber is ageing faster than the tread is wearing. Recent replacements should also be confirmed, as the 2026 test recorded front tread depths as low as 1.6 mm centrally, indicating that the tyres fitted at that test were already at or beyond the point of legal non-compliance. The brake system has been broadly stable across the recorded tests, with rear brake pad wear advisories in 2023 and 2024 being the only items recorded, and no further brake-related advisories since. Given the intervening two-year gap, a buyer should expect that the rear pads may now require replacement again and should check pad thickness through the wheel spokes and feel for any binding or pulling under light braking. As this A-Class is now eleven years old, the test drive should include careful listening for any squealing or groaning from the brake calipers, particularly after the vehicle has been driven in wet conditions, as seized caliper slide pins can develop on low-mileage cars that experience frequent short journeys. Under the vehicle, inspect the rear brake flexible hoses for any cracking or swelling, the exhaust system for corrosion at the mounting rubbers and joints, and the underside of the engine for any oil seepage from the rocker cover gasket, all of which are age-related items consistent with a vehicle of this vintage and recorded mileage.
