2004 MG ZR: 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 63% pass first time (all 2004 cars: 57%) Stands out: drive shaft (cv) joints 2×, rust around suspension or steering mountings 1.9×, battery 4.1× 1,831 MOTsSee the petrol guide › Diesel 64% pass first time (all 2004 cars: 57%) Nothing stands out above the usual rate 186 MOTsSee the diesel guide ›

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