2013 Mercedes-Benz A-Class 1.5L Diesel · ST63 OFU

A pattern of recurring electronic and lighting defects, punctuated by a significant failure involving multiple safety-critical systems, defines the mechanical history of this vehicle. While the most recent test on 11 November 2025 resulted in a pass, it followed a severe failure in October 2025 that flagged major faults with the anti-lock braking system (ABS), electronic stability control, the electronic parking brake, and the engine malfunction indicator lamp (MIL). Furthermore, the exhaust emissions were recorded as exceeding manufacturer limits during that same period. The presence of an oil leak advisory in the latest test suggests that while the major electronic and emission issues were addressed, the vehicle still requires monitoring for fluid loss. The recorded mileage of 106,087 miles over approximately 13 years represents an average annual accumulation of roughly 8,161 miles. This usage pattern is considered typical for a vehicle of this age, suggesting a consistent level of road use rather than prolonged periods of inactivity or excessive high-speed motorway mileage. Mechanically, this level of usage implies that consumables such as brakes, tyres, and suspension components will be subject to standard wear, but the record does not indicate the extreme mileage-related degradation often seen in high-use commercial or long-distance vehicles. Prospective buyers should focus heavily on the electrical and braking systems during a physical inspection. Given the recent major failures involving the ABS, electronic stability control, and the electronic parking brake, it is essential to verify that no warning lamps illuminate on the dashboard during startup or while the vehicle is in motion. A test drive should include testing the parking brake's engagement and release mechanism and checking for any hesitation or error messages in the electronic stability control system. Any intermittent dashboard warnings regarding the engine MIL or braking systems would indicate that the previous major faults may not have been fully rectified. Attention must also be paid to the lighting and fluid integrity. The MOT history shows a chronic trend of advisories regarding clouded or discoloured headlamp and position lamp lenses, which should be checked for clarity and effective illumination. Regarding the recent oil leak advisory, a thorough inspection of the engine bay is necessary to identify the source of the leak. During the test drive, listen for any unusual noises from the exhaust system and monitor the engine's idling stability to ensure the previous emission failures and MIL malfunctions are resolved. Finally, check for any vibration or pulling that might suggest issues with the previously noted fractured wheel rim or underlying suspension components.
