2021 Vauxhall Insignia SE NAV Turbo D 1.5L Diesel · RL06 RML

The 2021 Vauxhall Insignia SE Nav Turbo D passed its most recent DVSA MOT test on 2 December 2025 with no defects or advisories recorded, indicating that the vehicle met all statutory roadworthiness requirements at that examination. Reviewing the available history, the prior test on 23 September 2024 also resulted in a pass, but it carried three advisories relating to brake pad wear at both the front and rear axles and a superficial cut to the offside front tyre sidewall. The absence of any advisory items on the latest pass suggests that those wear-related concerns were likely addressed through routine servicing between the two tests, demonstrating a maintenance trend that appears stable and responsive rather than deteriorating. There are no recorded failures, dangerous defects, or structural advisories in the documented history, which is a positive indicator for a prospective buyer. With a recorded mileage of 37,642 miles over approximately five years of age, this Insignia has covered an annual average of around 7,500 miles, which sits broadly in line with typical usage for a vehicle of this class and age. This neither suggests prolonged periods of standing, which can accelerate corrosion on brake discs and degrade battery health, nor excessive motorway mileage that would prematurely wear clutches, turbochargers, or suspension components. The relatively moderate annual mileage does mean that certain calendar-based service items become particularly relevant, as fluids degrade with time irrespective of distance covered, and rubber components can perish through age even when tread depth remains adequate. Given that the 2024 advisory noted thin front and rear brake pads, it is prudent to confirm with the seller whether these have since been renewed and to inspect the current pad and disc condition directly. Even thin pads can progress to a stage where they cause brake shudder under heavy application, audible squeal, or extended stopping distances, while worn pads allowed to contact the discs may necessitate machining or replacement of the discs themselves. On a test drive, listen for any grinding or squealing from the wheel areas, particularly on light initial application, and feel for vibration through the steering wheel or brake pedal that would suggest lipped or corroded friction rings, a common issue on vehicles of this age even with modest mileage. The advisory concerning the offside front tyre cut should likewise be verified; the tyre should be inspected for any subsequent sidewall damage, cracking, or perishing consistent with a five-year-old carcass, and replacement considered if the DOT date code indicates it is approaching six years of age regardless of remaining tread. Beyond the recorded advisories, a physical inspection should focus on areas susceptible to age-related deterioration. Inspect all four tyres for sidewall perishing and verify manufacture dates, as older tyres can lose structural integrity even with legal tread remaining. The 12-volt battery should be load-tested, particularly given the moderate annual mileage, as short journeys and periods of inactivity reduce battery longevity. Examine the underbody, wheel arches, and brake calipers for any signs of surface corrosion or binding, a known concern on vehicles that may have seen extended standing periods between shorter journeys. Verify that the timing belt or cam belt interval has been observed according to Vauxhall's manufacturer schedule, that the diesel particulate filter has no warning lights illuminated, and that the service book or digital history confirms regular oil and filter changes at appropriate intervals. Finally, ensure that brake fluid, coolant, and transmission fluid have been renewed in accordance with calendar recommendations, as these degrade chemically over time irrespective of mileage, and their condition is critical to the long-term reliability of the braking, cooling, and drivetrain systems on this turbo-diesel Insignia.
