2016 Vauxhall Insignia 1.6L Diesel · BA16 FSV

The most recent MOT, dated 9 June 2026, resulted in a failure. The test recorded significant advisories on both rear tyres – inner‑edge wear approaching the legal limit, cracking and perishing – together with corrosion on the front and rear sub‑frame mounting points and a worn rear suspension arm bush. Earlier examinations show a pattern of recurring tyre wear, progressive sub‑frame corrosion, intermittent oil leaks and a rear brake disc that has been noted as pitted and scored on several occasions. While the vehicle did pass in 2025 and 2024, the trend over the past five years is clearly moving towards deteriorating condition rather than stabilising, with the 2022 dangerous tyre bulge being a particular red flag. At 162 651 mi the car has accumulated roughly 16 300 mi per annum, well above the average for a ten‑year‑old family saloon. Such a mileage level accelerates wear on consumables – tyres, brake discs, pads and suspension components – and places additional stress on the engine and drivetrain. High annual mileage also suggests the vehicle has spent considerable time under load, which can hasten oil seal degradation and increase the likelihood of corrosion on mounting points that are exposed to road salt and moisture. There are no obvious mileage gaps that would indicate long periods of storage, so the wear observed is consistent with continuous use. A prospective buyer should give the rear tyres immediate attention. Inspect the sidewalls for any cracking, perishing, or bulging, and measure tread depth across the width; the inner edges are already close to the legal minimum and may need replacement on both axles. During a test drive listen for a low‑frequency clunk when the rear wheels are loaded over bumps, which would indicate the worn rear suspension arm bush is allowing excess movement. Check the rear brake pedal for any pulsation or sponginess, and have the rear discs measured for thickness and surface condition – pitting can lead to reduced braking efficiency and uneven pad wear. The advisories about sub‑frame corrosion merit a visual inspection of the front and rear mounting areas; look for flaking rust, especially around the bolt holes, and ensure there is no excessive play in the engine mounts. The recorded oil leak from the drive‑shaft seal should be verified by a mechanic, as a leaking seal can lead to loss of lubrication and eventual bearing damage if left untreated. Beyond the immediate tyre and brake concerns, confirm that all exterior lights, particularly the rear fog lamp, are operational and that no water remains in the fog‑lamp housings, which can cause electrical faults. A thorough check of the 12‑V battery’s cranking voltage and electrolyte level (if applicable) is advisable given the vehicle’s age. Verify that the coolant, brake fluid and engine oil have been changed at appropriate intervals – fluid degradation is time‑based as well as mileage‑based – and look for any signs of corrosion on the battery terminals and ground straps. Finally, obtain a full service history; a recent timing‑belt or chain change, if required on this model, would be a strong indicator of proactive maintenance. Negotiating a price that reflects the imminent tyre replacement, suspension bush refurbishment, brake servicing and corrosion treatment will help ensure the car is safe and reliable for further use.
