Reliability, common problems and owner reviews for the Opel Corsa D 1.2 / 1.4 petrol (Twinport / Ecotec). Check this before you buy used.
The small petrols are otherwise simple, but the defining issue is timing-chain wear: the chain stretches between 80,000–120,000 km (most pronounced on the 1.2 75hp and 1.4 90hp), giving a cold-start rattle that, ignored, leads to engine damage. Crucially, these need oil changes at no more than 15,000 km with the specified 5W-30 to protect the chain.
