2018 Vauxhall Insignia 2.0L Diesel · XG04 LAN

The latest MOT test passed on 23 September 2025, following a failure for a major tyre defect. The overall maintenance trend appears to be transitioning from a stable period into one of emerging mechanical concerns. While the vehicle maintained a clean record in 2023, the subsequent years have seen a rise in advisories, most notably a recurring oil leak between the engine and the gearbox. This progression suggests that while the vehicle is currently roadworthy, it is entering a phase where more intensive mechanical attention and preventative maintenance will be required to avoid more significant and costly failures in the near future. The recorded mileage of 61,514 miles is consistent with the vehicle's age, representing an average annual usage of approximately 7,689 miles. This level of usage is typical for a private vehicle and indicates that the car has been driven regularly enough to avoid the specific issues associated with long-term stationary periods, such as brake seizure or fluid degradation. However, at this mileage and age, the vehicle is approaching a stage where wear on consumable items like suspension bushes, drive belts, and cooling system components becomes more prevalent, so a thorough check of the service history is essential to ensure these intervals have been respected. A primary concern for any prospective buyer is the advisory regarding the oil leak between the engine and the gearbox. While the DVSA noted it was not excessive at the time of testing, this is often a symptom of a leaking rear main seal or a gasket issue. During your test drive, listen for any unusual engine noises and check for any burning oil smells, particularly after the engine has been under load. You should also inspect the engine bay and the area where the engine meets the transmission for any signs of active weeping or heavy residue. Additionally, following the recent failure for a tyre cut reaching the cords, you must inspect all tyres for sidewall damage, perishing, or uneven tread wear, which could indicate alignment issues or the need for a full set of replacements. You should also investigate the condition of the braking system, given the previous advisories for pitted and scored rear brake discs. During testing, apply the brakes firmly to check for any shuddering through the pedal or any grinding noises that might suggest the discs have not been adequately replaced or that the calipers are beginning to bind. Furthermore, check the underside of the vehicle for signs of excessive corrosion on the exhaust system and structural components. Given the vehicle's age, it is also prudent to verify the health of the 12V battery and ensure that all fluid changes, including coolant and brake fluid, have been performed according to the manufacturer's time-based intervals rather than just mileage.
