2016 Vauxhall Insignia 2.0L Diesel · DP16 XDC

The most recent DVSA examination on 3 December 2025 recorded a clean PASS with no advisories or defects noted, and this follows an identical clean pass on 30 December 2024 and a further pass on 11 June 2024. Taken together with the earlier clean pass of 17 February 2023 (issued immediately after rectification of the same-day failure), the maintenance trend over the last three years is firmly stable and improving, with no advisories raised in any of the recent tests. The only historical concerns stem from a cluster of faults in early 2023, all of which were remedied at the time and have not reappeared in subsequent examinations. There is no evidence in the DVSA record of persistent structural corrosion, recurring brake or suspension issues, or ongoing exhaust or lighting defects, suggesting the vehicle has been returned to a sound mechanical state. Annual mileage of approximately 8,777 miles is broadly typical for a ten-year-old Insignia and sits comfortably within the expected usage band for a vehicle of this age and class. There are no significant gaps in the recorded mileage progression that would suggest long periods of standing, and equally no bursts of rapid accumulation that would point to high-wear motorway use. This moderate usage pattern generally means that consumables such as brake pads, discs and tyres will have been replaced on a sensible wear basis rather than urgently, while the drivetrain will not have been subjected to the elevated stress associated with very high annual mileages. Buyers should nevertheless satisfy themselves that the recorded odometer reading is consistent with the vehicle's general condition and service book. The recurring defect in the 2023 history was the Engine MIL (Malfunction Indicator Lamp) being inoperative or indicating a malfunction. On a pre-purchase test drive, the buyer should ensure the MIL extinguishes promptly when the ignition is switched on and that it does not reappear during running. Worth noting is that the lamp being inoperative can itself be a fault, meaning it may have failed to illuminate when the engine management system detected an issue, which can mask underlying emissions, sensor, or catalytic converter faults. Given this is a diesel or petrol Insignia approaching ten years of age, it would be prudent to have any stored diagnostic trouble codes read with an OBD scanner and to verify that the vehicle's emissions, including diesel particulate filter regeneration behaviour on diesels, are functioning correctly. The 2023 tyre-related dangerous defects are not a forward-looking concern, as they were rectified at the time, but they serve as a reminder to check that all four tyres are currently of adequate tread depth, are of matching type and age, and show no signs of uneven wear that might point to geometry or suspension component issues. Given the vehicle's age, several calendar-based checks merit attention regardless of the clean recent MOT history. Tyres fitted in the last year or two may still suffer sidewall perishing and cracking from age, particularly if the car has spent time parked outside, and should be inspected visually for ozone damage. The 12V battery should be load-tested, as batteries typically degrade after five to seven years and a failing unit can produce erratic electrical behaviour that mimics sensor faults. Brake discs may have developed light surface corrosion from standing or infrequent use, and calipers can bind after periods of inactivity, so a test drive should include firm, steady brake applications from higher speeds to check for pulling, shudder, or uneven feel. Coolant, brake fluid and (where applicable) automatic transmission fluid all degrade with time rather than mileage, so verify their service intervals have been observed and look under the car for any signs of fluid weeping from the engine, power steering, or undertray area. Finally, confirm that the cam belt or timing chain replacement interval has been observed according to manufacturer schedule, and inspect the underside for any emerging corrosion on suspension arms, springs and subframe mounting points, which are the most likely age-related structural concerns on a ten-year-old Insignia.
