2017 BMW 420 2.0L Diesel · V13 CBJ

The vehicle passed its MOT on 16 October 2025 with no defects recorded, which is the most recent test outcome and provides reassurance regarding its present roadworthy condition. The single failure on 3 October 2025 was limited to an inoperative horn, a straightforward electrical or fuse-related issue rather than a structural or mechanical concern, and the vehicle was re-presented and passed thirteen days later. The accompanying advisories from that failed test centred on nearside front and rear plus offside rear tyres worn close to the legal limit and a nearside rear brake pad nearing the end of its service life, all of which are normal wear items. The only other advisory in the entire history is a nearside rear inner tyre worn on edge from January 2025. Aside from these consumable observations, the MOT record is otherwise clean across eight tests stretching to 2020, indicating a broadly stable and consistent compliance pattern with no recurring structural or mechanical defects. The recorded mileage of 67,931 miles across approximately nine years equates to an annual average of around 7,548 miles, which is unremarkable for a vehicle of this age and profile. There are no significant gaps in the MOT history that would point to long periods of standing, nor any evidence of rapid mileage accumulation between tests that would suggest heavy commercial or motorway use. This level of usage is consistent with a privately owned car used primarily for short to moderate journeys, which can have its own particular implications: engines, gearboxes and drivetrains tend to be well exercised, but components susceptible to corrosion or drying out from infrequent long runs may merit closer inspection. Given the age of the vehicle and the rubber-related advisories on recent tests, particular attention should be paid to the tyres. Although the most recent pass recorded no defects, a nearside rear inner edge wear advisory has now appeared on consecutive tests, which can indicate a tracking misalignment, worn rear suspension bushes, or slight camber irregularities. On a test drive, listen for any clonking or thumping from the rear suspension over uneven surfaces, as the 4 Series is known to suffer from worn rear trailing arm bushes which can manifest as imprecise handling and uneven inner-edge tyre wear. The nearside rear brake pad advisory suggests replacement is now due, so the discs should be inspected for lipping, scoring or corrosion, particularly given that the vehicle may have had periods of lighter use where binding calipers can develop. With nine years of service and an average annual mileage, several age-related items warrant verification regardless of the favourable MOT history. Check the production date stamping on all four tyres, as rubber compounds degrade with calendar age even if tread depth remains adequate; sidewall cracking or perishing is a common issue on vehicles of this vintage. Inspect for surface corrosion around the wheel arches, underbody seams and suspension components, paying particular attention to brake disc surface rust which can lead to juddering under heavy braking if the discs have corroded unevenly. Verify the service history stamps in the book and ensure that brake fluid, coolant and the automatic or manual transmission fluid have been changed at their recommended intervals, as these degrade with time rather than mileage. Finally, given the inoperative horn issue recorded in October 2025, confirm the fault has been fully rectified and that the supplementary restraint system, battery health and any warning lights on the instrument cluster are all clear before purchase.
