2006 BMW 630 3.0L Petrol · RV06 ONT

The vehicle presents a generally stable maintenance trend, with the most recent test on 15 November 2025 at 157,981 miles passing cleanly with zero defects. That clean sheet is significant. It follows a retest on 14 November 2024 at 154,338 miles, which itself resolved a failed inspection from the previous day. The 2024 failure flagged an unsecured offside front bonnet, a worn nearside rear suspension arm ball joint, and a poorly supported offside rear brake pipe. All three were rectified before the retest passed. The TPMS warning lamp has been a persistent advisory across four consecutive tests since November 2022, suggesting the system has not been fully diagnosed or repaired. This is a minor electrical concern rather than a structural or safety-critical defect, but it warrants investigation. Overall, the record shows a vehicle that has had intermittent faults corrected rather than ignored, which is a positive indicator of responsible ownership. The mileage accumulation is consistent and unremarkable for a 2006 vehicle now at 157,981 miles. Annual usage sits at roughly 7,899 miles per year, which is typical for a grand tourer of this age. The intervals between tests show steady progression: 145,664 miles in November 2022, 150,620 in November 2023, 154,338 in November 2024, and 157,981 in November 2025. The gap between the 2023 and 2024 tests shows approximately 3,718 miles covered in twelve months, and the 2024 to 2025 interval added 3,643 miles. There are no suspicious gaps or sudden jumps in recorded distance. The vehicle appears to have been driven regularly rather than left standing for extended periods, which helps keep mechanical components exercised and fluids circulating. Buyers should focus their in-person inspection on the rear suspension and braking system. The November 2023 test identified slight play in the nearside rear upper suspension arm ball joint, and the November 2024 failure involved the same area on the offside rear. Suspension bushes and ball joints on BMW 6 Series models of this era are known wear items, and the fact that both sides have been flagged suggests the rear suspension may be approaching a broader refresh cycle. The offside rear brake pipe clipping issue from 2024 also deserves attention. A poorly supported brake pipe is vulnerable to chafing and fatigue over time, particularly on a vehicle that has covered nearly 158,000 miles. Inspect the full length of the rear brake lines for corrosion, especially where they pass through mounting brackets or along the subframe. The TPMS warning lamp remaining illuminated across four consecutive annual tests indicates a fault that has persisted for at least three years. This could be a failed sensor, a wiring fault, or a control module issue. It is not a roadworthiness failure, but it means the system cannot alert the driver to a sudden pressure loss. A diagnostic scan will be needed to pinpoint the cause. The bonnet latch fault from the 2024 failure was corrected, yet buyers should still verify the secondary catch operates correctly, as a bonnet opening at speed on a high-performance vehicle is a serious hazard. Given the clean November 2025 result, this BMW 630 appears to have been maintained to a reasonable standard, but the recurring rear suspension and brake system items suggest a careful mechanical inspection before purchase remains essential.
