2012 BMW 6 Series 3.0L Diesel · KS12 TKU

The vehicle remains roadworthy, but the maintenance trend shows a worsening condition regarding the front suspension geometry. While the most recent test in September 2025 at 127,311 miles passed, the tester flagged slight play in both the nearside and offside front suspension arm ball joints. This mirrors a defect recorded during the September 2024 test at 121,642 miles where the same components were identified. This indicates that the previous advisories were not addressed, and the wear is now progressive across the front steering assembly. The mileage pattern is consistent with a 14-year-old luxury grand, averaging approximately 9,000 miles per year. The record shows steady usage between 2021 and 2025, with a notable jump of over 12,000 miles between the 2023 and 2024 tests, followed by roughly 5,700 miles since then. This regularity suggests the car has been used consistently rather than left stationary for long periods, which typically helps prevent the degradation of rubber seals despite the age of the vehicle. A buyer must prioritize a thorough physical inspection of the front suspension to assess the extent of the ball joint play. Because this fault has appeared in two consecutive years without rectification, the components likely require immediate replacement to prevent a loss of steering precision or uneven tyre wear. The inspection should also check for signs of perished rubber on the control arm bushings, as the ball joints often fail in tandem with these components at this mileage. No structural corrosion or brake issues were noted in the recent history, so the focus remains strictly on the mechanical wear of the front-end assembly.
