2011 Vauxhall Insignia Excl NAV 158CDTI 2.0L Diesel · BN11 AEG

The Vauxhall Insignia’s most recent MOT test on 19 August 2025—just 11 months ago—confirms it remains roadworthy with no defects recorded. This pattern of consecutive passes, including the April 2025 test at 108,256 miles, suggests a stable maintenance history without recurring mechanical failures. The sole failure in April 2025 was an administrative anomaly (no defects logged), which does not indicate underlying issues. However, the proximity of the latest test to today’s date means no recent inspection has verified critical components like suspension integrity, brake hydraulic systems, or exhaust emissions compliance. Buyers should treat this as a baseline but prioritise an independent pre-purchase inspection to confirm no latent faults have developed since August 2025. The recorded mileage of 110,006 miles over 15 years equates to approximately 7,334 miles annually, a rate consistent with typical usage for this age. There are no significant gaps in mileage accumulation—each test interval spans around 4,000 miles, indicating regular driving rather than prolonged neglect or storage. The most notable observation is the 2025 April test dates clustered within five days (21st and 27th), which may reflect administrative retesting rather than mechanical issues. No abrupt spikes or prolonged inactivity are evident, though the lack of service records means wear on high-mileage components like suspension bushes, coil springs, and brake calipers cannot be confirmed from MOT data alone. Given the absence of defects in recent tests, the primary focus for a buyer should be the suspension system, particularly the rear bushes and coil springs, which are prone to fatigue at this mileage. The braking system—including rear binding calipers or warped discs—should be scrutinised, as MOT tests do not always catch subtle hydraulic or mechanical inefficiencies. Structural corrosion, particularly around wheel arches, sills, and the subframe, warrants inspection, especially given the vehicle’s age. Finally, the 1.58 CDTI diesel engine’s turbocharger and exhaust emissions system (DPF if fitted) should be checked for soot buildup or catalytic converter degradation, as these are common failure points in older diesel units. The clean MOT history is reassuring, but these areas demand hands-on verification.
