2011 Vauxhall Insignia 1.8L Petrol · MF61 CPX

The vehicle is currently roadworthy, but the maintenance history indicates a recent shift in mechanical condition. While it passed the test in November 2025 at 96,224 miles, this followed a failure just one day prior at 96,220 miles. The failure resulted from high exhaust carbon monoxide levels, suggesting a combustion efficiency issue or a sensor fault that required immediate attention to bring the vehicle back to emissions standards for the re-test. The mileage pattern remains consistent with low-intensity usage for a 15-year-old vehicle, averaging approximately 6,400 miles annually. There is a notable gap in records between April 2021 and December 2023, during which the car covered only 4,237 miles over twenty-one months. Since then, usage has increased, covering over 12,000 miles in the last three years. This transition suggests the vehicle has moved from periods of standing to more frequent regular driving, which can sometimes accelerate the degradation of rubber-based components and fluid seals despite the low odometer reading. A buyer must focus on the recurring oil leak identified during the November 2025 test. Although the tester deemed the leak not excessive at the time, its presence on an engine of this age often indicates failing valve cover gaskets or oil seals that will eventually require more costly intervention if not monitored. The previous emissions failure also necessitates a thorough check of the oxygen sensors, spark plugs, and fuel system to ensure the carbon monoxide issue was not merely masked. Given the age of the Insignia, a physical inspection for structural corrosion on the rear subframe and exhaust mounting is essential, as these are common points of failure for this model that do not appear in the digital history until they become critical.
