2004 Mercedes-Benz A-Class: 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: rigid brake pipes 2.1×, shock absorbers 2.5×, flexible brake hoses 2× 3,334 MOTsSee the petrol guide › Diesel 53% pass first time (all 2004 cars: 57%) Stands out: rigid brake pipes 2.2×, shock absorbers 2.9×, steering rack inner joints 3.8× 431 MOTsSee the diesel guide ›

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