2018 Vauxhall Insignia 1.5L Petrol · SA18 AAK

The most recent MOT test completed in February 2026 resulted in a pass, following a failure involving headlamp aim and a malfunctioning tyre pressure monitoring system. The maintenance trend appears to be reactive, with the vehicle requiring adjustments to lighting and electronic monitoring systems to meet compliance. While the most recent pass indicates these specific issues were rectified, the recurrence of headlamp alignment failures in previous years suggests that the lighting assembly or its electronic adjustment mechanisms may be prone to instability or wear. With 114,669 miles recorded, this 2018 Vauxhall Insignia has covered an average of approximately 14,334 miles per year. This represents high annual usage for a vehicle of this age, which typically implies more frequent long-distance or motorway driving. While consistent use can help prevent certain types of corrosion associated with vehicles that sit idle, it also means the vehicle has undergone significant mechanical stress. Components such as the suspension system, drivetrain, and braking hardware are likely subject to advanced wear and may require more frequent replacement than a lower-mileage equivalent. During a test drive, you should pay particular attention to the lighting and tyre monitoring systems to ensure the recent failures have been fully resolved. Verify that the headlamp beam pattern remains steady and does not fluctuate, which could point to failing electronic leveling motors or loose mounting brackets. Additionally, confirm that the tyre pressure monitoring system is fully operational with no warning lights on the instrument cluster. Given the 2024 advisory regarding front tyre wear on the edges, inspect the current tyres for uneven tread patterns; significant edge wear could indicate issues with wheel alignment, worn tie rod ends, or degraded suspension bushes. Due to the high mileage, a rigorous inspection of the chassis and running gear is necessary. Listen for any rhythmic knocking or clunking from the suspension when traversing uneven surfaces, which would indicate worn dampers, coil springs, or bushings. Check the brake discs for heavy scoring or excessive lip formation and ensure there is no sign of binding calipers or pedal shudder under braking. It is also vital to verify the service history for major interval items, specifically the timing belt and water pump, as well as the condition of the gearbox oil and coolant. Finally, inspect the engine bay and underside for any evidence of fluid leaks or exhaust system corrosion that may have developed over the high mileage.
