Known faults on the 2018 Vauxhall Corsa diesel

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

• Timing chain rattle

  These engines use a timing chain. Poor servicing wears the tensioner, and high-mileage cars can see the chain stretch, causing rattles and misfires.

  At the viewing: Start the engine from cold and listen for a rattle in the first few seconds. Ask for proof of yearly oil changes.

• Easytronic automated gearbox

  Easytronic versions only

  The Easytronic “automatic” is a manual with a robot clutch. The clutch still wears out and can be awkward to repair.

  At the viewing: If it’s an automatic, check whether it’s Easytronic and test it in slow traffic for slow or jerky changes.
