2011 Vauxhall Astra 1.6L Petrol · CK11 DZG

The 2011 Vauxhall Astra holds a valid MOT pass dated 27 November 2025 at 105,763 miles, yet the maintenance trend over the preceding twelve months is mixed at best. The vehicle failed on 10 November 2025 at 105,651 miles and again on 17 November 2025 at 105,759 miles, both times for the same combination of a Lambda reading outside specified limits on the second fast idle and worn, pitted rear brake discs. A persistent oil leak also appeared on both failures and the subsequent pass, where it was flagged as an advisory. The tester noted the nearside and offside rear brake discs as worn, pitted or scored but not seriously weakened on the pass certificate, suggesting the discs were replaced or refinished only to a borderline standard. The Lambda fault cleared by the final retest, but an emissions-related failure recurring across two consecutive attempts points to a catalytic converter operating at the edge of tolerance or a sensor fault that may return under different driving conditions. Mileage accumulation is broadly consistent with light-to-moderate use for a fifteen-year-old vehicle. The record shows 101,068 miles on 15 November 2024 and 105,763 miles on 27 November 2025, representing roughly 4,695 miles over twelve months. That is below the typical annual figure of around 7,000 miles for this age group, which may indicate shorter journeys or periods of limited use. The tight clustering of the three most recent tests within seventeen days in November 2025, covering just twelve miles between the first failure and the pass, is consistent with a retest cycle rather than genuine road use. No significant mileage gaps or anomalies appear in the supplied record. A buyer inspecting this Astra in person should focus on the rear braking system and the source of the oil leak. The rear brake discs were flagged as worn and pitted across three consecutive tests, and the pass certificate still carried an advisory on both rear discs, so the calipers should be checked for binding and the pads examined for uneven wear. The oil leak, present at every test since November 2024 and never resolved beyond advisory status, warrants a thorough inspection of the rocker cover gasket, oil filter housing, and crankshaft seals. The November 2024 failure revealed a fractured nearside rear coil spring, a seriously leaking offside front shock absorber, and a torn anti-roll bar linkage dust cover. Although the subsequent pass suggests these items were addressed, the front suspension should still be bounce-tested and the shock absorbers examined for fresh oil misting. Uneven inner-edge tyre wear noted on both axles in November 2024 hints at worn suspension bushes or incorrect tracking, and the nearside front suspension arm rear bush was flagged as worn at that test. A four-wheel alignment check and close inspection of all suspension bushes and ball joints would be prudent before purchase.
