2017 BMW 420 2.0L Petrol · YF17 VMH

A recurring theme of front suspension bush wear combined with progressive brake‑disc deterioration defines this 2017 BMW 420’s MOT record; the August 2026 test still passed but flagged both nearside and offside front suspension arm pins or bushes as worn, while earlier years showed rear brake disc and pad thinning and a 2023 failure for a severely worn front brake disc. The pattern shows wear items being noted year on year rather than new, unrelated failures, suggesting a gradual ageing of suspension and braking components rather than an abrupt fault. At 56,418 mi the car averages just over 6,200 mi per annum, a mileage figure that sits comfortably within normal usage for a nine‑year‑old executive saloon. The MOT history shows no large mileage jumps between tests and no gaps in annual testing, indicating the odometer readings are consistent with the recorded service intervals and that the vehicle has not experienced periods of intensive short‑term use that would accelerate component fatigue. When inspecting the front suspension, feel for any looseness or clunk when the steering wheel is turned over bumps and listen for rattles that could indicate the worn arm pins or bushings have begun to develop excess play. Examine the tyre wear patterns for asymmetry that might corroborate suspension movement, and check the steering response for any pull to one side. For the braking system, verify that the front discs are free of deep scoring and that the pedal delivers a firm, consistent bite without pulsation; a thin rear disc or pad will manifest as reduced rear‑end braking efficiency and may be accompanied by squeaking or a longer stopping distance. Given the repeated rear‑disc and pad advisories, a thorough visual inspection of disc thickness and pad wear is advisable before committing. The front windscreen washer system, which failed in 2023, should be confirmed as operational – a non‑functioning washer can be a safety issue in wet conditions. All four tyres have been flagged as close to the legal tread limit on several occasions, so a fresh set is likely required imminently. Addressing the front suspension bush wear and ensuring the brake discs are within the minimum thickness specifications will remove the current advisories and reduce the risk of future failures, delivering a more confident and compliant driving experience.
