2008 BMW 525 2.5L Diesel · SW04 EYN

The most recent MOT, carried out on 21 August 2025, resulted in a pass with a single advisory concerning a near‑side rear child‑seat that obstructs a full inspection of the adult belt. Over the past eight years the vehicle has consistently passed with no failures, the only recurring items being minor windscreen damage and tyre‑wear advisories on the rear wheels. This pattern indicates a generally stable maintenance record, with no evidence of deteriorating safety‑critical components, although the repeated tyre‑wear notes suggest the rear suspension or alignment may merit closer scrutiny. At 189 971 miles the car averages roughly 10 500 miles per annum, which sits squarely within the normal usage envelope for a 2008 model. There are no conspicuous gaps in the mileage log that would imply prolonged periods of inactivity, nor does the mileage suggest any extreme high‑speed or high‑load operation. Consequently the wear on consumables such as tyres, brake pads and engine oil is likely to be age‑related as well as mileage‑related, and the drivetrain components have been subjected to a moderate, steady load rather than a sudden high‑stress regime. Prospective buyers should give particular attention to the rear tyre condition. The MOT advisories in 2021 and 2023 flagged tread approaching the legal limit, especially on the inner edges, which can be a sign of rear‑wheel mis‑alignment, worn rear suspension bushes, or uneven loading. On inspection, verify that the tread depth exceeds 3 mm uniformly across the width, and look for cupping, sidewall cracking or foreign objects embedded in the tread. During a test drive, listen for a hollow thump or a pulling sensation when cornering, and feel for any vibration through the steering column that could indicate tyre imbalance or suspension degradation. Also remove the child‑seat to inspect the rear seat belt for fraying, proper retraction and secure anchorage; any compromised belt could be a safety issue that would need rectification before the next MOT. Given the vehicle’s age, additional time‑based checks are advisable regardless of the MOT record. Examine the windscreen for chips or cracks that could propagate, especially around the previously noted damaged area, and ensure the wipers make full, even contact. Inspect the under‑body for rust, particularly where the manufacturer’s covers are fitted, as concealed corrosion can affect structural integrity and exhaust mounting points. Test the 12 V battery voltage and check for any signs of electrolyte leakage; a battery over ten years old often requires replacement. Finally, confirm that the brake discs are free of excessive surface rust, the pads retain adequate thickness, and the calipers move without binding, and verify that engine oil, coolant and brake fluid have been changed within the recommended intervals, as fluids degrade with time even if the car is not driven heavily.
