2004 BMW 525 2.5L Diesel · S9 BDO

The vehicle is currently roadworthy, having passed the most recent MOT on 16 February 2026 at 235,776 miles, but the tester recorded slight play in both rear upper suspension arm ball joints and both front lower anti‑roll‑bar linkage ball joints. The presence of these advisories, without any prior mentions, indicates a nascent suspension issue that could develop if not addressed. Overall the maintenance trend appears stable, with the only new concern emerging in the latest test. At 235,776 miles the car averages roughly 10,700 miles per year over its 22‑year life, a mileage level that sits within normal expectations for a 2004 BMW 525. The record shows a steady increase of about 13,900 miles between the February 2025 and February 2026 tests, matching the annual average and suggesting no periods of prolonged inactivity. No large mileage gaps or abrupt spikes are evident, and the MOT entries are consistently spaced at twelve‑month intervals, indicating regular testing and likely regular servicing. A prospective buyer should give particular attention to the rear suspension ball joints and the front anti‑roll‑bar linkages, probing for excess movement or noise that could signal wear beyond the slight play noted. The near‑side rear tyre was flagged close to the legal limit in February 2025; confirming tread depth and uniform wear is advisable. The brake hose deterioration recorded in February 2024 was remedied before the subsequent pass, so a visual inspection of all brake hoses and a functional test of the braking system are prudent. Finally, a thorough check for any corrosion on the chassis and under‑body, as well as a review of the condition of the steering rack and bushings, will help verify that the emerging suspension advisories have not progressed to structural concerns.
