2006 Vauxhall Signum 1.9L Diesel · KU06 MRP

The 2006 Vauxhall Signum presents a stable and reassuring roadworthiness profile. The most recent test on 12 September 2025 at 146,549 miles resulted in a clean pass with zero defects recorded. This outcome, combined with a consistent pattern of passes across the last three years, indicates a well-maintained vehicle with no recurring mechanical or structural faults flagged by DVSA testers. The maintenance trend is stable and improving, as the car has moved from a period of repeated failures to consecutive clean passes. The mileage accumulation tells a clear story of consistent, moderate use. Between the September 2023 test at 120,762 miles and the September 2025 test at 146,549 miles, the car covered approximately 25,787 miles over two years, averaging around 12,893 miles annually. This is higher than the lifetime average of roughly 7,327 miles per year, suggesting recent owners have been using the car more intensively. The jump from 138,835 miles in September 2024 to 146,549 miles by September 2025 alone accounts for 7,714 miles, which is entirely typical for a single year. No suspicious gaps or plateaus appear in the record that would indicate long periods of disuse or odometer anomalies. Despite the clean MOT record, a buyer should still conduct a thorough physical inspection. The repeated failed tests on 29 August 2025 and 13 September 2024, both at nearly identical mileages to their subsequent passes, suggest the previous owner addressed specific defects promptly before retesting. This pattern implies responsive rather than neglectful ownership, but it also means the underlying faults that caused those failures deserve scrutiny. Inspect the braking system closely, including calipers, discs, and pads, as binding or uneven wear is a common cause of MOT failure on this platform. Check the suspension components, particularly front lower arm bushes, anti-roll bar links, and coil springs, which deteriorate with age and mileage on the Signum's heavy chassis. Examine the underside and sill areas for corrosion, as structural rust on a twenty-year-old Vauxhall can develop rapidly if undersealing has degraded. The exhaust system and emissions control components, including the catalytic converter and lambda sensors, should also be assessed given the car's age and the potential for marginal emissions to trigger failures between tests.
