2015 Vauxhall Insignia 2.0L Diesel · DN15 TYP

A clean pass at the most recent test on 5 November 2025, with no advisories or defects recorded, gives a strong current indication of roadworthiness for this 2015 Vauxhall Insignia. However, the broader history shows a pattern of straight pass-or-fail outcomes with no recorded advisories on any of the three passes and no documented reasons on either of the failures. While this means there is no specific component flagged as a recurring weak point, the inability to pass on first attempt in consecutive years (failing on 4 November 2025 and 30 October 2024, each time passing on the immediate retest) does warrant some scrutiny. It suggests the vehicle may sit right on the boundary of pass-fail criteria and that whatever caused each failure was remedied quickly enough to clear the retest the following day, leaving no recorded defect detail for a prospective buyer to review. The mileage of 94,099 across approximately eleven years works out to a typical annual accumulation of around 8,500 miles, which is broadly consistent with average private use rather than high-mileage motorway driving or low-mileage short-trip running. There are no obvious anomalies in the recorded mileage progression between tests, no large gaps that would suggest extended periods off the road, and no sudden jumps that might indicate clocking or missed tests. From a mechanical perspective, this average rate of use means consumables such as brake pads, discs, tyres, and the clutch (if manual) will have seen normal wear, and there is no particular reason to suspect premature degradation of internal engine or transmission components from low-mileage neglect or, conversely, excessive wear from high annual mileage. Given the absence of specific advisory detail, a buyer should focus inspection effort on the areas most commonly prone to wear on a diesel or petrol Insignia of this generation and mileage. On a test drive, listen for clonks or knocks from the front suspension over bumps, particularly from the lower control arm bushes and anti-roll bar drop links, and feel for vagueness or wandering through the steering that could point to worn tie rods or power steering rack wear. Apply the brakes firmly from speed and check for any pulling to one side, pedal judder, or grinding that would indicate warped discs or binding calipers, and inspect the wheels and tyres for uneven wear patterns that might suggest alignment or suspension geometry issues. It is also worth carrying out a thorough visual check underneath and around the engine bay, as MOT records do not capture every developing issue. Look for any signs of oil seepage from the cam cover or sump, weeping coolant from the water pump or thermostat housing, and any surface corrosion on suspension arms, subframe mounting points, or brake and fuel lines running along the underbody. Check that all dashboard warning lights extinguish promptly on startup, that the air conditioning blows cold, and that there are no unusual smells, rattles, or hesitation under acceleration. Given the immediate-retest pattern in the MOT history, asking the seller directly what was repaired between each failure and retest is sensible, as the absence of recorded advisories leaves that detail unverified.
