2017 Vauxhall Insignia 2.0L Diesel · DL17 PLU

The Vauxhall Insignia’s most recent MOT test on 2025-09-06 at 106,986 miles confirms it remains roadworthy, with no defects recorded over the past two cycles. The absence of advisories or repeated failures across five tests—including a single retest in 2024—suggests no persistent mechanical issues. However, the 2024 retest at 96,801 miles, just 315 miles after the initial failure, indicates a brief but unnecessary delay in rectifying whatever minor issue prompted the initial stop. This is not a cause for alarm but warrants scrutiny of the specific component that failed then, as it may recur or degrade further. The mileage progression shows consistent usage, averaging around 11,887 miles annually, which aligns with typical wear patterns for a vehicle of this age. Notably, there is a 12,928-mile gap between the 2022 and 2023 tests, followed by a more regular 13,928-mile interval to the 2024 failure. While this suggests the car was likely stored or underused for a period, the lack of corrosion advisories in recent tests implies it was protected from prolonged exposure. The 2024 retest’s proximity to the initial failure also hints at prompt attention to maintenance, though buyers should verify whether the issue was addressed permanently or merely masked for the retest. Given the clean MOT history, priority should be given to inspecting high-wear components that often fail without warning: the suspension bushes and coil springs, particularly at the rear where binding or uneven wear is common in this model. The brakes, while not flagged in tests, should be checked for uneven disc thickness or warping, especially if the vehicle exhibits a pull or reduced stopping power. Corrosion is less likely given the recent passes, but a thorough examination of wheel arches, subframes, and sills is advisable to confirm no hidden structural weaknesses. The absence of emissions-related failures does not preclude a gradual decline in engine efficiency, so a smoke test and idle check would be prudent. Finally, the 2024 retest’s timing suggests reviewing service records for any unresolved electrical or sensor-related issues, as these can sometimes trigger false failures.
