2009 BMW 525 2.5L Petrol · YN09 FFX

The most recent MOT, carried out on 3 December 2024, was passed with no recorded defects, indicating that the vehicle presently meets the statutory safety and emissions standards. Earlier examinations show a mixed picture: a clean pass in 2015, followed by a series of failures in 2016 (excessively deteriorated anti‑roll‑bar dust covers), 2018 (front‑tyre sidewall damage and cuts) and 2019 (brake pads reduced to the wear indicator and a brake‑fluid warning lamp). Since those incidents the record has been free of failures, suggesting that the owner has addressed the major safety items and that the overall maintenance trajectory is now improving. At 82 614 miles the car has averaged roughly 4 800 miles per year over its 17‑year life, which is considerably below the typical UK usage pattern. Such low annual mileage often points to periods of infrequent use or extended storage, rather than heavy‑duty driving. While the reduced wear on power‑train components is a benefit, prolonged standing can accelerate the ageing of rubber components, battery plates and corrosion‑prone metalwork, and can allow brake discs to develop surface rust if the vehicle has not been moved regularly. A prospective buyer should give particular attention to the tyre condition. The 2018 advisories noted front‑tyre sidewall cuts and perishing; even if the tyres have been replaced since, the age of the current set should be verified by checking the DOT code and inspecting for cracking, dry rot or uneven wear that could indicate mis‑alignment or suspension issues. Examine the front brake assembly for pad thickness, disc surface condition and any signs of uneven wear or glazing, as the 2019 failure showed the pads at the wear limit and a brake‑fluid warning. Verify that the brake fluid has been flushed within the last two years, and look for any moisture ingress or a soft pedal during a test‑drive, which would manifest as a spongy feel or increased stopping distances. Because the car has likely spent long periods stationary, inspect the under‑body for rust, especially around the wheel arches, suspension mounting points and the anti‑roll‑bar dust‑cover areas that previously failed. Check the condition of the suspension bushes, ball‑joint boots and steering rack for cracks or excessive play that could produce clunking noises when cornering or over bumps. Test the 12‑volt battery voltage and, if possible, perform a load test; an aged battery may struggle in cold weather. Finally, confirm that routine service items such as engine oil, coolant, transmission fluid and the timing‑chain oil have been changed at appropriate intervals, as calendar‑based degradation can affect reliability even on low‑mileage vehicles.
