2016 BMW 320 2.0L Diesel · EK66 UNE

The 2016 BMW 320 most recently passed its MOT on 31 March 2026, albeit with an advisory recorded for light oil misting on the offside rear shock absorber. While the pass is positive, the broader trend over the past twelve months is concerning and suggests some deterioration in maintenance discipline or component condition. In the weeks preceding that pass, the vehicle suffered two failed tests, including dangerous defects for a nearside rear tyre worn down to the cords and a fractured nearside rear road wheel, alongside major defects for an inoperative windscreen washer, an excessively fluctuating offside front service brake, and a malfunctioning tyre pressure monitoring system. The rapid succession of failures in February and March 2026, followed by a pass, indicates a concentrated remedial effort rather than steady upkeep, and any prospective buyer should treat the earlier dangerous items as a warning sign that critical safety components were allowed to reach an unacceptable state before being addressed. With 90,652 miles recorded over approximately ten years, this 320 has covered around 9,000 miles annually, which is broadly typical for a vehicle of its age and not unusual for a premium saloon that may have seen a mix of commuting and longer motorway journeys. There are no large unexplained gaps in the MOT record that would suggest prolonged standing, although the absence of an MOT entry between December 2021 and December 2023 should be noted and may indicate either a period off the road or simply that the early 2023 test was the first applicable one following a recent test. The mileage progression between recorded tests appears consistent and does not raise concerns of clocking or inconsistency, but the annual rate is sufficient to have generated meaningful wear on suspension, braking, and drivetrain consumables over the vehicle's life. The recurring advisory and failure items warrant particular attention during any pre-purchase inspection. The light oil misting on the offside rear shock absorber noted at the most recent test should be monitored, as shock absorbers gradually weep seals before failing more dramatically, and on a test drive you should listen for any clonking or knocking from the rear over uneven surfaces and watch for excessive pitching or wallowing through corners. The recent dangerous failure for the nearside rear road wheel being fractured is serious, as a fractured wheel is a structural and catastrophic safety risk; confirm exactly what was replaced, ensure the replacement wheel is of the correct specification, and inspect all four wheels and tyres for cracks, corrosion, or impact damage. The offside front brake fluctuation flagged as a major defect could indicate a seized slider, worn caliper guide pins, a warped disc, or contamination, so on a test drive apply the brakes firmly from speed and feel for any pulsing, vibration, or pulling to one side, and verify the car stops in a controlled, straight line without juddering through the steering. Given the vehicle's age and mileage, a number of age-related checks are also advisable regardless of the MOT record. Inspect the tyres not only for tread depth but also for sidewall cracking and perishing, which are common on older rubber even when tread remains legal, and check that all four tyres are of matching make, type, and age where possible. Examine the brake discs for any heavy corrosion or lipping, as standing moisture and salt exposure can cause surface rust and pitting, and confirm the caliper slide mechanisms are free and not binding, which is a known issue on lightly used or intermittently driven BMWs. Verify the 12 volt battery's state of health, as a ten year old original unit is almost certainly due for renewal, and review the service history to confirm that brake fluid, coolant, and gearbox or differential oil have been changed on a calendar basis rather than purely by mileage, since fluids degrade with time. Finally, check for any oil leaks from the valve cover gasket and filter housing, both common failure points on the N20 or B48 engines fitted to this generation of 3 Series, and ensure there are no warning lights or fault codes stored, particularly relating to the tyre pressure monitoring system which only recently passed after a recorded malfunction.
