2012 BMW X5 3.0L Diesel · YY12 DGO

The 2012 BMW X5 holds a valid MOT pass certificate dated 5 February 2026, tested at 124,907 miles, but the maintenance trend over the preceding twelve months is clearly worsening. The vehicle failed its 31 January 2026 test on four items, including a split nearside front outer constant velocity boot and a deteriorated offside front lower suspension rod ball joint dust cover. A retest just five days later on 5 February passed, yet the tester still flagged the same suspension ball joint dust cover as severely deteriorated and recorded a persistent oil leak, albeit deemed not excessive. This pattern indicates the owner addressed the CV boot failure to secure a pass but left known suspension and fluid-weep issues unresolved, suggesting a reactive rather than preventative maintenance approach. The mileage accumulation is broadly consistent with the vehicle's age, averaging roughly 8,900 miles per year. Between 4 February 2025 at 116,677 miles and 5 February 2026 at 124,907 miles, the vehicle covered approximately 8,230 miles in twelve months, which sits comfortably within typical annual use for a part-time family or commuter SUV. The MOT record itself is sparse before 2022, with clean passes noted on 11 August 2022 at 98,776 miles and 6 February 2024 at 107,579 miles, leaving a gap of over two years with no recorded tests between 2022 and 2024 that a buyer should query directly. A prospective buyer should inspect the offside front lower suspension arm ball joint and its dust cover in person, as the repeated advisory across both the January and February 2026 tests points to ongoing deterioration that will eventually allow contamination into the joint itself, leading to wear, play, and costly suspension work. The oil leak flagged in both 2026 tests warrants underbonnet inspection to identify the source, whether that is a valve cover gasket, oil filter housing seal, or crankshaft seal common on BMW N55 and N63 engines. The nearside rear tyre worn to the legal limit and the child seat obstructing the offside rear adult belt inspection in three consecutive tests are minor but telling signs that basic consumable checks and interior preparation were overlooked. A thorough underbody inspection for corrosion, particularly around rear subframe mounting points and sills, is advisable given the vehicle's age and the absence of any structural advisories in recent records that might have flagged earlier corrosion treatment.
