BMW M31997 · 3.2L PETROL

Most recent MOT (23 May 2026 – PASS) The car passed the test but still carries three recorded defects: a minor front‑exhaust leak, corrosion on the nearside front brake pipe (covered in grease), and a damaged off‑side steering‑rack gaiter. These are all advisory items (non‑fatal) but they point to ageing components that have not yet caused a failure. Recurring pattern Over the last twelve months the same three issues appear repeatedly (exhaust leak, brake‑pipe corrosion, steering‑rack gaiter damage). In addition, the vehicle suffered a series of electrical faults in 2024‑2025 – multiple indicator lamps, stop lamps and registration‑plate lamp were all reported as inoperative or showing wrong colour, and the exhaust emissions were out of spec at that time. The electrical failures were largely cleared by the 2025‑04‑29 pass, but the mechanical defects have persisted. Trend analysis The defect list has not grown; rather, the number of items has reduced from a large suite of lighting and emissions failures in 2024‑2025 to the three advisory items seen in 2026. This suggests a stabilising trend – the most serious electrical problems have been remedied, but wear‑related parts (exhaust, brake pipe, rack gaiter) are now the limiting factors. The vehicle is not showing a worsening failure rate, but the remaining defects are likely to become safety‑relevant if left unattended. Mileage versus age At 105,000 mi the car averages about 3,600 mi per year, which is low for a 29‑year‑old BMW. Low mileage can indicate gentle use, which may have preserved major drivetrain components.
