2011 Vauxhall Astra 1.7L Diesel · SD11 ADX

The Vauxhall Astra’s most recent MOT test, conducted on 27 March 2026 , confirms the vehicle remains roadworthy with no defects recorded. However, the immediate preceding test on 26 March 2026 —just one day earlier—was a failure, despite the same mileage (128,263) being logged. This anomaly suggests either a temporary administrative error or a last-minute correction, as the vehicle passed again after minimal mileage accumulation. Beyond this, the pattern over the past three years shows consistent pass-fail cycles at the same mileage thresholds (124,209 and 128,263), with no defects ever recorded. While this implies no recurring mechanical failures, the repeated retesting at identical mileages warrants scrutiny of whether the vehicle was driven to the test station specifically to pass, rather than undergoing genuine maintenance. The recorded mileage of 132,810 miles over 15 years aligns closely with the average annual distance of approximately 8,854 miles , which is typical for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, suggesting steady usage without prolonged periods of neglect. The most notable observation is the identical mileage figures for the 2025 and 2026 failures, which could indicate the vehicle was driven to the test station repeatedly to achieve a pass, rather than being maintained between intervals. This pattern may reflect either diligent servicing or, conversely, a lack of proactive upkeep between MOT cycles. Given the absence of defects in the MOT history, a buyer should prioritise an independent inspection of suspension components , particularly the rear bushes and coil springs , as these are common wear items on this model that often fail without MOT failings. The rear brakes should be checked for uneven wear or binding calipers, as repeated test cycles without faults could mask underlying issues. Additionally, corrosion should be assessed at the sill seals, wheel arches, and subframe mounts , as this model is prone to rust progression over time. The exhaust system and emissions controls —though not failed—should be verified for leaks or degraded components, as these can degrade silently. Finally, the transmission fluid and power steering reservoir should be inspected for contamination or low levels, as these are often overlooked but critical for long-term reliability.
