2010 Vauxhall Insignia 1.8L Petrol · LT10 EFB

The 2010 Vauxhall Insignia presents a stable but mechanically weary roadworthiness profile. The most recent test on 2022-08-01 at 134,605 miles passed, yet it carried the same low-level advisories seen repeatedly since 2020. A minor exhaust gas leak at the flexible joint, an oil leak deemed non-excessive, and a deteriorating front registration plate were all flagged again. This pattern suggests cosmetic and minor fluid-weep issues have been tolerated rather than resolved. Crucially, the 2020 failure for an inoperative engine MIL and a faulty ESC warning lamp points to a previous episode where active dashboard faults were present, though these were rectified before the retest later that same day. Mileage accumulation tells a story of near-standstill use in recent years. The car covered roughly 3,797 miles between the July 2019 test at 116,581 miles and the August 2020 test at 127,679 miles. From August 2020 to August 2021, it added 3,797 miles, and then it recorded zero miles of use between the August 2021 test at 131,476 miles and the August 2022 test at 134,605 miles, a discrepancy that strongly suggests a replacement speedometer or a prolonged period off the road. The annual average of roughly 8,413 miles is typical for the model, but the recent stagnation raises questions about long-term sitting and potential deterioration of rubber components and brakes from lack of use. A buyer should focus the physical inspection on the front exhaust flexible section, which has leaked minor exhaust gases across three consecutive annual tests. This joint is a known fatigue item on the Insignia and a worsening leak here can escalate into a dangerous exhaust manifold crack or carbon monoxide ingress into the cabin. The persistent oil leak, repeatedly noted as not excessive, likely originates from the valve cover gasket or camshaft sensor seals. While minor, it can contaminate the ignition coils and lead to rough running if left unaddressed. The offside front anti-roll bar ball joint dust cover and the offside rear shock absorber dust cover, both flagged as severely deteriorated or detached in 2021, were not mentioned in the 2022 test, but this absence does not confirm replacement. Exposed joints allow grit ingress, accelerating wear and causing knocking over bumps. Have these components physically checked for play. The 2020 failure for an engine management light and electronic stability control fault is a significant flag. The MIL was either deliberately obscured or the underlying fault was cleared for the retest. A buyer must plug in a diagnostic scanner and read fault codes and readiness monitors to confirm no current or pending engine or ESC faults exist. The repeated condensation advisory on the nearside headlamp is cosmetic but can reduce light scatter at night if the lens seal has finally failed. Finally, the car has not been tested since August 2022, meaning it is now nearly four years past its last MOT. A full inspection of brake disc thickness, caliper slide pins, and suspension bushes is essential, as standing corrosion on these components can be more damaging than mileage wear.
