2017 BMW 330 3.0L Diesel · AV67 PCO

The vehicle most recently passed its MOT on 16 October 2025, with a single advisory recorded for an offside rear tyre that was noted as worn close to the legal limit and worn on its edge. Prior to this, the vehicle recorded four consecutive passes from 2021 through 2024 with no advisories or defects, and an additional advisory pair in October 2020 for both rear tyres exhibiting similar inner or middle-edge wear patterns. The overall pattern is one of stable compliance with MOT requirements, with the rear tyres being the only recurring theme. The fact that the advisory has now appeared across two test cycles separated by five years suggests a persistent geometry or suspension characteristic rather than isolated tyre degradation, and the edge wear specifically indicates that the issue is unlikely to have been permanently resolved simply by fitting new rubber. With a recorded mileage of 39,984 miles across approximately nine years, this 330 has covered an annual average of around 4,443 miles, which is substantially below typical usage for a vehicle of this age. Such low mileage often reflects a mix of shorter urban journeys and extended periods of standing, both of which carry their own mechanical implications. The MOT records, which are spaced at roughly annual intervals, show no large gaps that would suggest the vehicle was off the road for prolonged periods, but the cumulative effect of light use and irregular running should not be underestimated. The 2.0-litre diesel or petrol engines fitted to the F31 generation 330 are robust in terms of outright durability, but they are particularly sensitive to short journeys and infrequent operation, where oil, fuel, coolant, and brake fluid can all degrade on a calendar basis rather than a mileage basis. Given the recurring rear tyre edge wear advisories, particular attention should be paid to the rear suspension geometry and bushes on inspection. A test drive should be conducted over uneven road surfaces, listening for any clonking or knocking from the rear axle, as worn trailing arm bushes, coil springs, or top mount components are known contributors to uneven inner-edge wear on rear tyres. Any wandering instability at speed, particularly over undulating roads, or a feeling that the rear end is unsettled, would warrant further investigation of the rear suspension and a four-wheel alignment check. The nearside front tyre should also be examined, as uneven wear patterns can sometimes migrate to the opposite axle once geometry compensation occurs. Beyond the recorded advisories, the age and low mileage profile demands careful attention to items that deteriorate through time rather than use. Tyre sidewalls should be inspected closely for perishing or cracking, as rubber compounds degrade regardless of tread depth, and tyres over six years old should generally be replaced on safety grounds even if they appear serviceable. The 12V battery is likely nearing the end of its service life and should be load tested, as chronic undercharging from short journeys is a common cause of premature failure. Brake discs should be examined for surface corrosion, particularly on the rear calipers, which can bind on vehicles that have stood for extended periods, and a thorough check for any fluid leaks from the coolant expansion tank, power steering reservoir, and undertray area is essential. Finally, the service book and BMW service history should be verified, as the condition-based servicing schedule on these vehicles relies on accurate records, and confirmation that the timing chain, oil filter housing gasket, and fuel injector seals have been attended to would be prudent given the model's known service items at this age.
