2010 Mercedes-Benz A-Class 1.5L Petrol · BF10 FWR

Chronic corrosion of the braking system is the primary mechanical concern for this vehicle, with a trend of deteriorating brake pipe integrity appearing in recent years. While the vehicle passed its latest test on 6 February 2026, the record shows a progression from a clean history to major failures in 2025 involving excessively corroded rear brake pipes and a worn offside front lower suspension arm ball joint. The persistence of advisories regarding corroded front brake pipes across the 2025 and 2026 tests indicates a systemic issue with the condition of the brake lines. A total recorded mileage of 81,150 miles over sixteen years represents a low annual average of approximately 5,072 miles. This usage pattern suggests the vehicle has spent significant time stationary or has been used for short-distance journeys, which often correlates with the type of surface corrosion seen on brake lines and suspension components in the UK climate. The consistency of the annual testing interval suggests the vehicle has remained in active use rather than suffering from multi-year gaps in roadworthiness. Particular attention must be paid to the current state of the front brake pipes, as they have been flagged as corroded and covered in grease or other materials in two consecutive years. A physical inspection should verify if these pipes have been replaced or merely treated with a protective coating to mask the corrosion. During a test drive, the buyer should monitor for any soft or spongy pedal feel and ensure there is no pulling to one side under heavy braking, which would relate to the previous failure regarding service brake efficiency. The previous failure of the offside front lower suspension arm ball joint requires verification that the replacement part is functioning correctly. Listen for knocking or clicking sounds when traversing uneven road surfaces or during low-speed steering manoeuvres. Additionally, the frayed offside front seat belt webbing noted in February 2025 should be inspected to ensure it has been repaired or replaced, as this constitutes a safety defect.
