The 1.2 and 1.4 work best in the Corsa D, but timing chain issues can blight ownership, especially if oil and filter change intervals haven’t been followed scrupulously. Incidentally, the official regime is every 12 months or 20,000 miles, but Karl Ward from Autovaux recommends doing it much sooner.
The other major niggle with the D is the crankcase breather pipe, which runs from the cam cover to the throttle body – it can swell and split, resulting in noxious fumes entering the cabin. There
are two hoses – a thick and a thin one – but they’re not expensive to replace.
Other things to watch for include head gasket issues and clogged EGR valves on diesels. The latter costs from around £70 at independents and £163.20 from a main dealer. The diesel engines also have a dual mass flywheel, so beware any cars that rattle or vibrate when coming on and off the clutch, as a new DMF is £536.40 from Vauxhall.
Autovaux told us that the rocker covers on the Corsa D can also prove problematic and lead to poor running if the valve inside seizes; it sells replacements from around £120.
Keep an eye on coolant levels, too, as leaks from the radiator are common.

The 1.3 CDTI is reasonably swift and fuel efficient, but watch for blocked EGR valves and worn dual mass flywheels.
