2020 Vauxhall Astra SRI NAV Turbo CVT 1.3L Petrol · BT70 FWY

A clean pass was secured at the most recent MOT on 2 October 2025, but the overall mechanical story is one worth scrutinising rather than accepting at face value. Prior to that pass, the vehicle failed the same day on a major defect relating to the engine management indicator lamp, suggesting a malfunction indicator lamp issue that was evidently resolved in the short window between the failure and the re-test. The previous test cycle in December 2024 also required a same-day re-test, this time for an offside headlamp aim recorded as too low, before passing cleanly. While both failures were addressed swiftly, the presence of two same-day failures within roughly ten months indicates intermittent electrical or sensor faults that may recur, particularly on a turbocharged petrol engine of this generation. The 2023 test passed without recorded defects, so the late-2024 and mid-2025 issues represent a recent deterioration rather than a long-standing pattern. Annual mileage accumulation averages around 7,419 miles over six years, which is broadly typical for a vehicle of this age and avoids the pitfalls of either excessive motorway use or prolonged standing. There are no lengthy gaps in the testing record and no evidence of the vehicle being off the road for multiple consecutive years, so corrosion-related advisories on structural components or brake lines are less likely to have developed through disuse. The relatively modest annual figure suggests moderate wear on consumables such as brake pads, discs, tyres and clutch material, though the CVT transmission in this model is less susceptible to clutch wear than a manual equivalent. The mileage progression between tests appears consistent with the stated annual average, with no anomalous jumps that would suggest clocking or inconsistent use. A prospective buyer should pay particular attention to the engine management system, given the recent MIL inoperative failure. On a test drive, monitor the dashboard for any illuminated warning lamps, particularly the engine management or EPC light, and note any hesitation, rough idle, or momentary loss of power which could indicate an intermittent sensor fault, coil pack issue, or catalytic converter concern. It would be prudent to check whether any diagnostic trouble codes remain stored in the ECU using an OBD reader, and to confirm that any recent repair work is supported by invoice evidence. The headlamp aim failure, while straightforward to rectify, suggests verifying that both headlamp levelling mechanisms operate correctly and that the offside unit has not been knocked out of alignment by a minor impact or aftermarket bulb replacement. Beyond the recorded failures, the general mechanical inspection should focus on the areas most likely to show wear at this mileage. Listen for any knocking or clonking from the front suspension over uneven surfaces, which could indicate worn wishbone bushes or anti-roll bar links common on Astra models of this era. Check the brake pedal feel for any sponginess or excessive travel, and inspect the brake discs visually for lipping or scoring, as these will be original fitment by now. On the CVT, ensure transmission changes are smooth without any juddering or slipping, particularly when pulling away from standstill or climbing gradients, as any harshness could foreshadow costly repairs. Finally, inspect the underbody and subframe mounting points for any early signs of surface corrosion, given the turbocharged powertrain and typical UK operating environment, even though the MOT record does not yet show corrosion advisories at the six-year point.
