2015 BMW 430 3.0L Diesel · 4 BSY

The most recent MOT, dated 10 October 2025, was passed with only a minor windscreen chip recorded. This follows a 2023 failure where a serious fluid leak was identified on the off‑side rear shock absorber and several suspension arm bush wear advisories were issued. Since that failure the vehicle has cleared two successive tests without any major defects, indicating that the principal fault has been remedied and that the overall maintenance trend is now stabilising rather than deteriorating. With a recorded 128 630 miles on the odometer and a first registration in 2015, the car averages roughly 11 700 miles per year. This is within the normal range for a premium executive saloon of its age and suggests a balanced pattern of use rather than prolonged periods of storage or extreme high‑mileage abuse. No significant mileage gaps appear in the MOT history, so wear on consumables such as tyres, brakes and suspension components is likely to be consistent with the mileage rather than being accelerated by short‑term high‑load duty cycles. The buyer should give particular attention to the rear shock absorber on the off‑side, confirming that the leak has been fully rectified and that the damper is free of oil seepage, noisy rebound or uneven ride height. The front suspension arms on both sides were flagged for pin or bush wear in 2023; inspect the bushings for cracking, looseness or excessive play when applying steering torque, and listen for clunking over bumps. Tyre tread depth should be measured on all four wheels, as advisories in 2021 and 2022 noted front and rear tyres approaching the legal limit; look for uneven wear patterns that could indicate mis‑alignment or worn suspension components. The windscreen chips, while minor, should be examined to ensure they have not expanded and do not compromise structural integrity, especially around the driver’s line of sight. Given the vehicle’s age, a comprehensive age‑related inspection is prudent. Check the condition of the tyre sidewalls for cracking or dry rot, as rubber can perish after six to eight years regardless of tread depth. Verify the health of the 12 V battery, looking for corroded terminals and a voltage reading above 12.6 V after a short idle. Examine brake discs for surface rust, scoring or glazing, and ensure calipers move freely without binding. Inspect all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – for correct levels and signs of contamination, remembering that many fluids degrade on a calendar basis and should be replaced at least every two to three years even if mileage is low. A full service history, including any recent suspension or shock absorber work, will provide additional confidence in the car’s roadworthiness.
