2021 Vauxhall Astra: petrol or diesel?
Petrol, diesel and hybrid versions go wrong in different ways, so each has its own figures from the MOTs these cars had during 2023–2025. Pick the one you’re looking at: the fuel is on the logbook and in the car’s MOT history.
Hybrid versions had too few MOTs for figures of their own, or weren’t sold.

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.
- 1.0 petrol and 1.6 diesel
Brief loss of power with a metallic noise
The 1.0 petrol and 1.6 diesel can briefly lose power with a metallic noise. On diesels, a faulty oil pressure sensor is one cause.
At the viewing: Drive it for 20 minutes or more. Any sudden dips in power or engine warning lights are a reason to ask questions.
Front suspension creak
A worn lower arm bush makes a creak over speed bumps.
At the viewing: Drive slowly over a speed bump and listen at the front.
