2009 BMW 525 2.5L Petrol · YN09 FGZ

The vehicle’s most recent MOT activity on 2023‑05‑04 shows a failed test for a supplementary restraint system warning lamp (7.1.6(a)), despite a concurrent pass. The history records a progressive deterioration of brake‑related components—brake pipe corrosion in 2021, worn discs and hoses in 2020, and recurring pad wear from 2014 onward. Suspension issues, notably anti‑roll bar linkage dust‑cover ingress, appear repeatedly from 2017 to 2018. Tyre condition has also been a persistent concern, with ply exposure in 2022 and multiple advisories on tread wear and damage. Overall, the maintenance trend is worsening rather than stabilising. Mileage accumulation at 92,769 miles over roughly 17 years equates to about 5,500 miles per year, a low figure for the model’s age. The MOT entries are complete from 2013 through 2023, but the gap since the last test exceeds three years, which is outside the standard annual interval. This hiatus means the vehicle has not been officially assessed for roadworthiness for a considerable period, raising questions about unrecorded wear or repairs. A prospective buyer should inspect the brake circuit for signs of corrosion on both rear and front‑to‑rear pipes, verify that pads and discs are within wear limits, and check rear brake hoses for deterioration. Suspension components demand scrutiny of the anti‑roll bar linkage ball‑joint dust covers and associated joints for dirt ingress. Tyre condition requires a visual check for ply exposure, cuts, and uneven wear, as well as valve‑stem integrity. The oil system should be examined for leaks, and the supplemental restraint system warning lamp must be investigated for proper operation. Finally, under‑trays and any hidden underside panels should be inspected for corrosion or damage that may have been concealed.
