2015 Volvo XC60 2.4L Diesel · KT64 AJX

A pattern of rear suspension corrosion and a coolant weep sit at the centre of this Volvo's mechanical story, and both warrant close attention even though the vehicle has continued to pass every annual MOT since 2022. The 2022 test recorded advisories for both rear coil springs as corroded alongside a non-excessive coolant leak from the offside front area, while the 2023 test repeated the nearside rear coil spring advisory and added worn anti-roll bar linkage pins or bushes at both rear corners. By the 2024 and 2025 tests the record shows no advisories at all, and the most recent examination on 26 May 2026 passed with only a minor defect for an inoperative registration plate lamp on a multiple-lamp unit. Taken together, the data suggests the rear suspension wear has not yet crossed the failure threshold, but the earlier advisories indicate components that are progressively ageing rather than items that have been resolved. Mileage accumulation is broadly typical for the vehicle's age, with 121,369 recorded miles over an eleven-year life equating to an average of roughly 11,000 miles per year and no apparent gaps in annual testing since at least 2022. The absence of recorded tests between 2015 and 2022 means the early and mid-life service history cannot be verified through MOT data, so any conclusions about how the car was driven, loaded, or maintained during its first seven years must remain tentative. For a diesel or petrol XC60 of this age and mileage, consumption of braking components, front suspension items, and drivetrain mounts tends to accelerate once annual mileage remains consistently in the five-figure range, so a physical inspection of these wear items is sensible. For a test drive, focus on the symptoms that the recorded advisories would naturally produce. Listen for clonks or rattles from the rear suspension over speed humps and uneven tarmac, which would suggest the corroded coil springs have begun to fracture or that the worn anti-roll bar linkage bushes have loosened further; a noticeable leaning body roll through faster corners can point the same way. With the engine at operating temperature, watch the coolant expansion bottle for any active bubbling, smell for sweet coolant vapour around the offside front of the engine bay, and check the level after the drive, as the 2022 advisory described a leak that was not yet excessive but has had four more years to develop into a header tank top-up requirement or a hose failure. Beyond the flagged items, inspect the underside carefully for any progression of surface corrosion on the rear subframe, trailing arms, and brake pipe runs, as coil spring corrosion on a Volvo of this era frequently accompanies broader underbody oxidation. Examine the rear brake discs for lipping and the callipers for smooth release, given the annual mileage band, and confirm the anti-roll bar drop links and end bushes by hand for any free play now that they were first flagged in 2023. Finally, verify that all registration plate lamps illuminate correctly, as the recent minor defect is trivial to remedy but worth confirming has been resolved before purchase.
