2018 Vauxhall Insignia 1.6L Diesel · MM18 FKB

The most recent MOT test conducted in January 2026 resulted in a pass, though it introduced two notable advisories that warrant caution. While the vehicle showed no defects in 2025, the transition into 2026 has seen the emergence of an engine noise advisory and structural corrosion on the front subframe. This indicates a shift in the maintenance profile from a period of stability to one where age-related mechanical and structural degradation is becoming apparent. The presence of these advisories suggests that while the vehicle remains roadworthy, it is entering a phase where more significant preventative maintenance may be required to avoid future failures. The recorded mileage of 81,777 miles for an eight-year-old vehicle equates to an annual average of approximately 10,222 miles. This represents typical, moderate usage for a UK vehicle, suggesting that the car has likely been used for regular commuting rather than being subjected to extreme motorway mileage or long periods of stationary neglect. From a mechanical standpoint, this usage pattern is predictable, meaning that components such as suspension bushes, coil springs, and various seals should be showing expected signs of wear but should not be prematurely exhausted. Prospective buyers should pay particular attention to the engine noise reported on startup. During a test drive, particularly when the engine is cold, listen for any rhythmic tapping, heavy knocking, or irregular rattling, as these symptoms can point toward issues with the timing belt, tensioners, or valve train components. Furthermore, the advisory regarding central front corrosion to the subframe is a serious matter. You should inspect the underside of the vehicle to assess the severity of the oxidation. While currently classified as an advisory, if the corrosion is deep or causing metal thinning, it could eventually impact the structural integrity of the chassis. Regarding the braking and tyre history, although the 2023 advisories for worn pads and pitted discs were not repeated in 2025, the previous history of uneven tyre wear and perishing rubber suggests a need for scrutiny. Check the current tyres for any signs of sidewall cracking or uneven wear on the edges, which could indicate misaligned geometry or worn suspension components. During the test drive, monitor the brake pedal for any shuddering or pulsation, which would indicate warped discs, and listen for any grinding noises or signs of binding calipers that might suggest the previously worn components have not been adequately addressed or are wearing prematurely again.
