2019 BMW 420 2.0L Petrol · HT19 UBN

A clear pattern of inner-edge front tyre wear dominates the MOT history of this 2019 BMW 420, appearing as an advisory on the offside front in 2023 and reappearing on both front positions alongside the offside rear at the most recent test on 8 April 2026. The vehicle has passed every annual inspection since 2023, with a clean record in 2024 and only minor advisories otherwise, indicating a broadly sound structural and mechanical state. However, the only failure recorded, on 1 April 2023, resulted from a missing nearside rear wheel bolt, a serious road safety defect caused by a missing fastener rather than component wear. The progression from a single wheel fixity issue in 2023 to repeated edge-wear advisories through to 2026 suggests that the tyres are being asked to cope with a persistent geometry or suspension issue rather than simple age-related deterioration, and this should be treated as the primary area of mechanical concern for any prospective buyer. The recorded mileage of 51,969 miles over seven years equates to an average of roughly 7,400 miles annually, which is broadly typical for a car of this age and is unlikely to indicate either long-term storage or heavy commercial use. There are no unusual gaps in the testing record and no evidence of sudden mileage spikes between tests, so the wear visible at MOT inspections can be read as incremental rather than the product of a sudden change in duty cycle. At this annual accumulation, the consumables such as brake pads, discs, tyres and the 12V battery will have seen moderate but not excessive use, although components subject to age-related degradation such as rubber bushes, coolant hoses and the timing chain service interval on the B48 or B20 engines fitted to the 4 Series should be considered alongside the mileage figure. Given the recurring inner-edge wear advisory on the front tyres, any inspection should begin with a thorough check of the front suspension and steering geometry. Specifically, the condition of the front control arm bushes, wishbone bearings, top mounts and drop links should be examined, as worn bushes on the BMW 4 Series are a known source of uneven tyre wear. The offside rear has also been flagged twice, so the rear suspension bushes, trailing arm bushes and any adjustable camber components should be inspected for play or cracking. A four-wheel alignment check is strongly advisable, as the pattern is consistent with a persistent negative camber or toe setting that has not been corrected between tests. On a road test, listen for clonking or knocking from the front suspension over speed bumps and uneven surfaces, which would indicate worn control arm or anti-roll bar bushings. Check for steering pull to one side, vague on-centre feel, or any vibration through the wheel that could point to misalignment. Inspect the inner and outer edges of all four tyres for stepped wear, as uneven shoulder wear is a classic symptom of geometry issues on this platform. Finally, verify that all five wheel bolts are present and correctly torqued on each corner, and confirm with the seller that the missing bolt noted in 2023 was replaced with the correct BMW-spec fastener, as a mismatched bolt is a potential safety concern.
