My son has has numerous warning lights appear on the dashboard of his 2012 Volkswagen Polo 1.2 TSI. He immediately took it to a local garage and was told it needed a new part. They assured him the car was fine to drive until the part was delivered; but 10 days later the car broke down with timing chain failure.

As a gesture of goodwill the garage has agreed to waive labour charges, but my son still has to buy a replacement engine at a cost of over £1200. We believe that the garage are responsible as they gave bad advice to keep driving car. Do you have any advice please and do we have any legal possibilities to recoup money?
