2017 BMW 420 2.0L Diesel · AA17 ADE

The vehicle exhibits a pattern of recurring suspension and braking system concerns, with multiple advisories and failures indicating potential wear or neglect in critical components. The 226 MOT revealed serious fluid leaks in the nearside front shock absorber and excessive wear in the offside front anti-roll bar linkage, alongside tyre edge wear nearing legal limits. These findings, combined with prior advisories for worn suspension bushes and brake discs, suggest a history of gradual mechanical degradation. While the latest test passed, the presence of major failures and repeated advisories highlights ongoing maintenance needs, particularly in the suspension and braking systems. The 224 test also flagged dangerous brake pad thicknesses and parking brake inefficiency, underscoring systemic issues that may require urgent attention. The vehicle’s mileage of 77,3 miles over nine years aligns with typical annual usage, averaging approximately 8,559 miles per year. This rate suggests consistent, moderate driving rather than prolonged inactivity or excessive wear. However, the absence of MOT records prior to 224 raises questions about potential gaps in maintenance history, as the vehicle’s 217 registration would have been eligible for its first MOT in 218. The 224 failures, including dangerously thin brake pads, indicate possible deferred maintenance or heavy usage, which could accelerate component wear. While the mileage itself is unremarkable, the combination of recurring suspension and brake issues implies that the vehicle may not have been maintained to optimal standards, particularly in the past three years. A thorough inspection should prioritise the suspension system, focusing on the nearside front shock absorber for fluid leaks and the anti-roll bar linkage for excessive play, which could cause handling instability. The brake system requires close scrutiny, with emphasis on the nearside rear brake pad condition and parking brake functionality, as both were previously flagged as dangerous. During a test drive, listen for unusual noises over bumps, which may indicate worn suspension bushes or shock absorbers, and check for brake pedal judder or uneven stopping distances, which could signal disc warping or pad wear. The offside rear tyre’s edge wear also warrants attention, as it may point to alignment issues or improper inflation, which should be verified during the inspection. The vehicle’s MOT history necessitates caution, as repeated advisories and major failures suggest unresolved mechanical vulnerabilities. While the 226 test passed, the underlying issues with suspension and braking components require proactive maintenance to ensure safety and reliability. Buyers should consider the cost of repairing these systems, particularly the shock absorber and brake pads, and assess whether the vehicle’s overall condition justifies its price. A detailed pre-purchase inspection by a qualified mechanic is strongly advised to confirm the extent of wear and identify any additional hidden faults not captured in the MOT records.
