2016 BMW X4 3.0L Diesel · FY66 CKK

The vehicle passed its most recent MOT test on 5 December 2025, having previously failed the day before on a straightforward lighting defect (an offside side repeater not working) which was clearly remedied prior to the re-test. Looking at the broader test history, the maintenance trend is broadly stable but shows a gradual accumulation of advisories relating to suspension components, which is consistent with the vehicle reaching a decade of service and now sitting on 118,400 miles. The 2023 and 2020 tests were entirely clean, while 2024 and 2022 carried multiple advisories concerning rear coil spring corrosion. Aside from this recurring suspension theme and a couple of minor steering and bodywork advisories, there are no major structural or safety-related failures on record, indicating the vehicle has generally been maintained to a serviceable standard, though the buyer should not ignore the pattern of chassis component wear that has been flagged across consecutive tests. The recorded mileage of 118,400 over approximately ten years equates to around 11,840 miles annually, which is broadly typical for a vehicle of this age and segment. There are no obvious gaps in the MOT record that would suggest long periods of standing, and the mileage accumulation appears steady rather than abrupt, which is generally favourable for wear-related components. That said, an X4 of this age and mileage will have consumed a full set of consumables and several major service items, including brake discs, pads, tyres, and potentially the timing chain service, so the buyer should expect that further significant maintenance items are due or imminent rather than being surprised by them. The most significant recurring advisory relates to corrosion on the rear coil springs, first noted in 2022 and again in 2024 on both the nearside and offside rear. Coil spring corrosion is a progressive condition that, if left unaddressed, can lead to spring fracture, which typically presents on a test drive as a noticeable clonking or rattling noise from the rear suspension over uneven surfaces, a loss of ride height on one corner, or instability under load. The 2022 test also flagged light misting of oil from the offside rear shock absorber, which at that stage was deemed advisory but warrants a physical inspection for further seepage, as damp or perished rear dampers will manifest as excessive bouncing, poor damping over successive bumps, or a vague, unsettled feeling at speed. The steering rack inner joint play noted on the offside front in 2022 should similarly be rechecked; symptoms include a vague or loose feeling in the steering, particularly around the straight-ahead position, or a slight knocking when turning lock to lock with the vehicle stationary. Given the age and mileage, the prospective buyer should also carry out several physical checks beyond the MOT record. Tyres of this age can suffer sidewall perishing and cracking from environmental exposure even if the tread depth remains adequate, so all four should be examined closely for hairline cracks in the rubber, and the manufacturing date codes checked. The 12V battery in a decade-old BMW is very likely due for replacement, particularly if the vehicle has spent any time unused; a flat or weak battery can cause electrical gremlins and warning light issues common to the brand. Brake discs may exhibit significant corrosion or lipping from age and standing, and the calipers, particularly the rear ones which on BMWs of this era can suffer from binding due to the integrated electric handbrake mechanism, should be checked to ensure they release cleanly. Brake fluid and coolant should be considered due for replacement on a calendar basis regardless of mileage, as both are hygroscopic and degrade over time. Finally, verify the service book stamping history and any BMW digital service records to ensure that the long-term maintenance, including the major items such as spark plugs, filters, and any automatic transmission fluid changes, has been carried out to schedule.
