2015 Mercedes-Benz CLS: 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 83% pass first time (all 2015 cars: 74%) Nothing stands out above the usual rate 516 MOTsSee the petrol guide › Diesel 80% pass first time (all 2015 cars: 74%) Stands out: wheel bearings 5.9×, link ball joint covers 3.7×, engine warning light 2.2× 8,162 MOTsSee the diesel guide ›

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