2015 Vauxhall Insignia Design Cdti ECO S/S 2.0L Diesel · FH15 NLC

The Vauxhall Insignia CDTi’s most recent MOT test on 2026-02-19 confirms it remains roadworthy, though the immediate preceding test on 2026-02-01—just 15 days earlier—was a failure without recorded defects. This anomaly suggests either a minor administrative oversight in the test centre’s records or a last-minute correction, as no defects were logged in either instance. The broader trend over the past three years shows consistent pass rates with no recurring mechanical issues, indicating the vehicle has not experienced persistent faults requiring major repairs. However, the lack of defects in failures raises caution—either the tester overlooked critical components or the vehicle’s condition fluctuated sharply between tests. The recorded mileage of 90,806 miles over 11 years reflects an average of approximately 8,255 miles annually, which is typical for a vehicle of this age. There are notable gaps between tests: 13 months between the 2023 and 2025 MOTs, and an unusually short 12-day interval between the two 2026 tests. The rapid accumulation of mileage between 2023-11-09 (81,194 miles) and 2023-11-21 (81,297 miles) suggests either a rushed retest or an error in mileage logging. Beyond that, the steady progression of mileage without extreme spikes or prolonged periods of inactivity implies the vehicle has been driven regularly, which could accelerate wear on suspension bushes, coil springs, and brake components. Given the absence of defects in the MOT history, the primary focus for an in-person inspection should centre on high-wear items that aren’t routinely tested. The suspension—particularly the rear coil springs and bushes—should be examined for uneven sagging or excessive play, as diesel engines like the CDTi often place heavier loads on these components. Brake discs and calipers, while not flagged in tests, may show uneven wear or binding if the vehicle was driven aggressively during the short 2026 test interval. Corrosion around wheel arches, sills, and the subframe is also critical, as the Insignia’s bodywork is prone to rust in wet conditions. Finally, the exhaust system should be checked for leaks or excessive corrosion, especially near the catalytic converter, which can fail without triggering an MOT defect if emissions remain within limits. The lack of advisories in past tests suggests no prior major issues, but these areas demand thorough scrutiny.
