2009 BMW 520 2.0L Diesel · LL09 XAF

The most recent MOT, carried out on 12 December 2025, was passed with no recorded defects, continuing a three‑year run of clean results following the 2022 advisory on the rear brake disc. Although the 2022 and 2021 advisories highlight wear on the rear disc and cuts on the front tyres, there have been no outright failures, indicating that the vehicle’s overall maintenance regime has been reasonably steady, with only minor, non‑critical issues emerging over the last five years. At 117,137 miles the 2009 BMW 520 averages just under 7,000 miles per annum, a usage pattern that is modest for a car of its age. The mileage record shows no large gaps that would suggest prolonged periods of inactivity, nor any spikes that would point to intensive short‑term use. Consequently the wear on high‑mileage components such as the engine, transmission and suspension is likely to be moderate, but the relatively low annual distance does raise the possibility of age‑related deterioration in parts that are more dependent on calendar time than on mileage. When inspecting the vehicle, give particular attention to the rear brake disc that was flagged in 2022 as worn, pitted or scored. Look for any pulsation or shudder when applying the brakes, especially under moderate to heavy braking, and examine the disc surface for deep scoring or excessive rust that could compromise braking efficiency. The front tyre cuts noted in 2021 should be re‑checked for any progression; any visible bulge, sidewall cracking or loss of tread uniformity could indicate that replacement is imminent. The parking‑brake lever ratchet identified in 2020 as worn should be tested for firm engagement and release; a loose or spongy feel may point to a failing parking‑brake cable or lever mechanism that will need adjustment or replacement. Beyond the recorded advisories, a vehicle of this age warrants a thorough age‑related inspection. Verify that the tyre sidewalls are free from cracking, dry rot or hardening, as ageing rubber can fail even on low‑mileage cars. Examine the suspension bushings, ball joints and coil springs for any signs of corrosion, leakage of grease or excessive play, which may manifest as clunking noises over bumps. Check the 12‑volt battery for voltage drop under load and inspect the terminals for corrosion, since batteries over 10 years often lose capacity. Finally, confirm that the engine oil, coolant, brake fluid and power‑steering fluid have been changed at appropriate intervals; fluid discoloration, sludge or a burnt smell are indicators that a service is overdue. A comprehensive visual and road‑test appraisal covering these points will give a clear picture of the car’s current roadworthiness and any near‑term maintenance that may be required.
