2004 BMW M5 4.9L Petrol · RX04 CXT

Most recent MOT (2025‑06‑02 – PASS) The car passed its latest test at 209,132 mi, but the report still flags three items that need attention: the front brake discs are worn and scored, the fuel pipe shows corrosion, and there is a small oil leak (not classed as excessive). None of these defects were deemed unsafe enough to fail the test, but they are all on components that deteriorate with age and mileage. Recurring pattern Across the four‑year MOT record the same groups of problems keep re‑appearing: Brake system – front and rear discs are consistently described as worn/pitted; in 2025 the rear discs were even listed as “seriously weakened”. Brake pipe corrosion is noted in every report from 2022 onward. Brake pads are also reported as thin. Corrosion – fuel pipe, several brake pipes, and various sections of the vehicle structure (inner sills, jacking points) are repeatedly flagged as corroded. Exhaust & emissions – multiple entries record minor to major exhaust leaks, a cracked catalytic converter, and elevated CO at idle. Steering / suspension – play in the steering rack inner joint, anti‑roll‑bar ball‑joint play, and fractured front coil springs were all noted in 2023‑2024. Minor electrical – a handful of lamp failures (position lamps, registration plate lamp) have been recorded, though none affect safety. These issues are largely mechanical wear and corrosion rather than isolated electronic glitches.
