Known faults on the 2010 Audi A1 petrol

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 wear (1.2 TSI petrol)

  1.2 TSI petrol (older engine)

  The older 1.2 TSI petrol uses a timing chain that can stretch. It starts as a rattle, especially when the engine first starts, and if it’s left the chain can fail and destroy the engine. Some garages advise changing it as often as every four years or 40,000 miles.

  At the viewing: Start the engine from cold and listen for a rattle in the first few seconds. Ask whether the chain has been changed, with an invoice.
