2012 SEAT Leon: 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 68% pass first time (all 2012 cars: 64%) Stands out: shock absorbers 2.6×, engine oil leaks 2.3×, exhaust system 1.9× 4,952 MOTsSee the petrol guide › Diesel 67% pass first time (all 2012 cars: 64%) Stands out: shock absorbers 2.7×, anti-roll bar link joints 3.3×, braking performance 2× 21,139 MOTsSee the diesel guide ›

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