2012 BMW 3 Series 2.0L Diesel · CK12 CUU

A recurring advisory for light oil misting on both rear shock absorbers dominates the MOT history, indicating that the suspension has been a consistent point of attention over several years. The first appearance of this issue was recorded in early 2021, and it re‑appeared on both the nearside and offside rear units in the 2023 test, while the 2022 test flagged only the nearside. Despite these advisories, the vehicle has passed every subsequent MOT without a failure, most recently on 4 December 2025, suggesting the problem has not progressed to a safety‑critical level but remains a maintenance item to monitor. At 121,772 mi the car averages roughly 8,700 mi per annum, a mileage rate that sits comfortably within normal usage for a 2012 model. The MOT record shows an uninterrupted annual testing pattern, with no multi‑year gaps that might hint at prolonged storage or unusually low utilisation. This steady accumulation implies that wear on consumables such as tyres, brakes and suspension components should be commensurate with the recorded mileage, and that the vehicle has been driven regularly enough for any developing faults to have been captured by the MOT inspections. Prospective buyers should give particular focus to the rear suspension during a pre‑purchase inspection. Inspect the shock absorber bodies for any fresh oil seepage and verify that the mounting points and bushings are free of corrosion or excessive play. On a test drive, listen for clunking or knocking noises when traversing road imperfections, and feel for a loss of rear‑end stability or excessive bounce after a firm brake application – both are classic signs of deteriorating damping. Because the rear shocks have been flagged repeatedly, budgeting for a full replacement of the rear shock absorber set is prudent, especially if the vehicle is to be used for spirited driving or carrying heavier loads. The tyre advisories recorded between 2019 and 2021, all concerning inner‑edge wear approaching the legal limit, also merit attention. Examine the tread depth across the width of each tyre, looking for uneven wear patterns that could point to mis‑alignment, worn suspension bushings or tyre pressure inconsistencies. If any tyre is close to the 1.6 mm legal minimum, replacement will be required. While no brake‑related defects have been reported, a visual check of the brake discs, pads and hydraulic lines is advisable, as the vehicle’s age and mileage typically bring these components within the service window. Addressing the rear suspension and tyre condition will directly improve ride quality and safety, providing a clearer picture of the car’s overall roadworthiness.
