2020 BMW 3 Series 2.0L Diesel · YJ69 RMB

The most recent MOT on 7 August 2026 was passed with no recorded defects, indicating that the vehicle currently meets the legal safety and emissions standards. Over the past three years the MOT record shows a consistent pattern of advisory items rather than outright failures: recurring slight play in both front track‑rod and lower suspension‑arm ball joints, a light oil mist on the near‑side front shock absorber, and a defective wiper blade. While these advisories have not escalated to failures, the repetition of front‑end suspension play suggests a gradual wear progression that has not yet required replacement but does merit close scrutiny. At 86,468 miles the 2020 BMW 3 Series has accumulated roughly 14,400 miles per year, which is above the average for a six‑year‑old executive saloon. This level of usage accelerates wear on consumables such as tyres, brake discs and pads, clutch (if a manual), and the front suspension components that are already flagged in the MOT advisories. There is no evidence of long periods of inactivity, so the wear is likely mileage‑driven rather than age‑related, meaning that parts subject to friction and load will be nearer the end of their service intervals. When you inspect the car, pay particular attention to the front steering and suspension. With ball‑joint play noted on two consecutive MOTs, you should listen for clunking or vague looseness when turning the wheel at low speed and when passing over bumps. Check for uneven front tyre wear, especially on the inner edges, which can indicate mis‑alignment or worn ball joints. A visual inspection of the ball joints and tie‑rod ends for torn rubber boots or corrosion is advisable, and a qualified technician should confirm the clearances. The shock absorber oil mist noted in 2023 may herald a developing leak; look for dampness or oil stains on the shock body and feel for reduced damping or excessive bounce during a test‑drive over a speed bump. Replace the defective wiper blade and verify that the new blade makes full contact across the windscreen, as poor visibility can be a safety issue. Given the car’s age and mileage, also examine the condition of the tyres for side‑wall cracking or dry rot, especially if they have been stored for long periods. Inspect the brake discs for surface rust, scoring or glazing, and ensure the pads have adequate thickness. The 12‑volt battery should be tested for cranking amperage, as high‑mileage vehicles often experience reduced charge retention. Verify that the service book shows regular oil and filter changes, coolant flushes, and that the timing chain (or belt, depending on engine) has been inspected at the manufacturer‑recommended interval. Finally, look for any signs of corrosion on the chassis, especially around the wheel arches and under the front splash guard, and ensure that all engine covers have been removed to allow a thorough visual check of belts, hoses and the underside of the engine for leaks or cracked components.
