2004 Vauxhall Signum: 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.

Petrol 55% pass first time (all 2004 cars: 57%) Stands out: exhaust system 2.6×, steering rack inner joints 4.7×, drive shaft (cv) joints 2.2× 284 MOTsSee the petrol guide › Diesel 53% pass first time (all 2004 cars: 57%) Stands out: number plate lights 2.4×, drive shaft (cv) joints 2.5× 205 MOTsSee the diesel guide ›

Hybrid versions had too few MOTs for figures of their own, or weren’t sold.
