2016 BMW 420 2.0L Petrol · PC02 WEN

The vehicle achieved an MOT pass on 20 January 2026, the most recent test in the recorded DVSA history, but it is essential to note that the same date also carries a failed Dangerous outcome for an exposed ply tyre on the nearside rear. This indicates the test was retaken and passed on the same day once the dangerous defect was rectified, which is permissible provided the repair is properly documented. Looking at the multi-year history, the maintenance trend shows persistent and recurring issues rather than a stable or improving profile. The nearside rear wheel distortion advisory has appeared annually from 2023 through 2026, steering rack inner joint play has been flagged at the last two tests, and tyre wear on the inner edges of the rear tyres has been a recurring advisories item, culminating in the 2026 dangerous failure for cord exposure. This pattern suggests the vehicle has underlying geometry or component issues that have not been fully rectified between tests. The recorded mileage of 57,625 miles over a ten-year span equates to an annual average of roughly 5,762 miles, which is well below the typical mileage for a vehicle of this age. While low mileage generally reduces wear on high-cycle components such as the clutch, engine internals and drivetrain, it introduces its own set of age-related concerns. Long periods of standing can lead to moisture accumulation in brake fluid, oxidation and flat-spotting of tyres even when tread depth appears adequate, corrosion on brake discs leading to judder or noisy operation, and degradation of rubber components including suspension bushes, drivebelt rubber and coolant hoses. The fact that the vehicle has covered enough miles to require multiple tyre replacements at the rear suggests it has been driven regularly enough to generate wear, but the pattern of inner-edge wear is more consistent with a geometry or suspension component issue than simple age-related deterioration. A prospective buyer should pay particular attention to the recurring rear wheel distortion advisory and the inner-edge tyre wear pattern documented across several tests. The nearside rear wheel has been flagged as slightly distorted on four consecutive tests, which warrants a close physical inspection for cracks, buckling or impact damage, particularly around the inner rim where the distortion was specifically noted on the 2026 test. Inner-edge tyre wear on both rear tyres is symptomatic of either incorrect wheel alignment, worn rear suspension bushes, weak coil springs allowing excessive negative camber, or sagging rubber torsion elements in the rear axle. On a test drive, the buyer should listen for clonking or knocking noises from the rear suspension over uneven surfaces, observe whether the vehicle tracks straight without pulling, and check for uneven acceleration or any instability under cornering loads. The steering rack inner joint play flagged in the last two tests should also be evaluated by turning the wheel lock to lock with the engine running and feeling for any knocking, roughness, or inconsistent resistance, as worn inner tie rod or rack joints can progress to affect steering precision and tyre wear patterns. Beyond the documented advisories, age-appropriate inspection items deserve attention given the vehicle's ten-year lifespan and low annual mileage. The 12V battery should be tested for cranking performance and voltage retention, as batteries that sit partially discharged can sulphate and fail without warning. Brake discs should be inspected for severe surface corrosion, particularly on the rear axle given the standing time implied by low annual mileage, and a test drive should confirm the absence of brake binding or uneven pulling. All fluid services should be verified by service history, as brake fluid absorbs moisture over time and should be replaced regardless of mileage every two to three years, while coolant, transmission fluid and differential fluid all have calendar-based service intervals that low mileage does not extend. Tyres should be examined for sidewall cracking and perishing even where tread depth remains legal, as aged rubber compounds lose flexibility and grip well before the tread wears down. Finally, the 2022 advisories regarding a non-functioning side repeater lamp and insufficient washer fluid are minor items but serve as a reminder to verify all exterior lighting and washer system functionality, including headlamp washers if fitted, as these are routinely checked at MOT and represent basic safety equipment.
