2011 BMW 520 2.0L Diesel · GY61 CZM

A persistent oil leak and recurring lighting faults define the recent mechanical history of this vehicle. While it passed its latest MOT on 21 February 2025, the record shows a consistent advisory for an oil leak appearing in both 2024 and 2025. Furthermore, the vehicle has suffered multiple failures related to position lamps and headlamp levelling systems over the last two testing cycles, indicating a trend of electrical or bulb failures that required remedial work to achieve a pass. The recorded mileage of 105,606 miles is typical for a fifteen year old vehicle, averaging approximately 7,040 miles per year. This steady accumulation suggests regular use, though the presence of heavily cracked and perishing tyres noted in 2022 and 2023 suggests there may have been intervals where the vehicle remained stationary or the tyres were left to age beyond their effective lifespan. Mechanically, this mileage level typically coincides with the expected wear of drivetrain consumables and suspension bushings. Inspection should focus heavily on the source of the oil leak flagged in the 2024 and 2025 tests. A physical check of the engine bay and the underside of the sump is necessary to determine if the leak is originating from the rocker cover, oil filter housing, or sump gasket. During a test drive, the buyer should monitor for any smell of burning oil upon acceleration, which occurs when fluid leaks onto the exhaust manifold. The lighting system, specifically the position lamps and the headlamp levelling device, should be fully operated to ensure the previous failures have been permanently resolved. Attention must also be paid to the current state of the tyres, given the history of cracking and edge wear recorded in 2022 and 2023. While these may have been replaced, the buyer should check for similar perishing on the sidewalls of any remaining tyres. Additionally, the windscreen should be inspected for the damage noted as a minor defect in 2022 and 2023 to ensure no cracks have propagated or now obstruct the driver's line of sight.
