2016 BMW 420 2.0L Diesel · AA66 ULL

A pattern of intermittent tyre and brake component issues has characterised this vehicle's recent testing history, though the most recent MOT on 16 February 2026 shows a clean pass with no defects or advisories recorded. While the 2022 inspection involved a dangerous failure due to a structural bulge in the offside rear tyre and a cut in the nearside rear tyre, the subsequent three years of testing have transitioned into a period of zero recorded defects. This follows a period between 2021 and 2023 where advisories were issued for thinning brake pads and edge wear on the offside front tyre, suggesting a trend of addressing consumable wear items as they approach legal limits. The recorded mileage of 83,157 miles over approximately ten years represents an average annual accumulation of roughly 8,316 miles. This usage profile is consistent with typical UK driving patterns for a vehicle of this age, suggesting the mechanical components have been subjected to regular, moderate operational cycles rather than prolonged periods of inactivity or heavy high-speed motorway use. This level of mileage typically means that while major drivetrain components may not have reached their end-of-life, wear on consumables such as suspension bushes, brake discs, and various rubber seals is expected to be at a stage where regular inspection is necessary. Given the history of advisories regarding brake pad thickness and tyre wear, a prospective buyer should pay close attention to the braking system and steering feel during a test drive. Listen for any rhythmic clicking or scrubbing sounds when turning the steering wheel at low speeds, which could relate to the previous tyre edge wear issues, and check for any pedal judder or vibration under heavy braking that might indicate uneven disc wear following the recorded pad thinning. It is also advisable to inspect the current condition of all four tyres for uneven tread wear patterns, particularly on the edges, to ensure the suspension geometry remains within specification. The previous failure involving tyre structural damage and bulges highlights the importance of a thorough visual inspection of the sidewalls for any signs of impact damage or bulging. While the recent records are clear, the history of brake and tyre advisories means the vehicle should be assessed for any signs of binding calipers or uneven braking pull. Ensure that the steering feels centered and that there is no wandering or pulling to one side, which would be relevant following the historical issues with tyre integrity and edge wear.
