While driving engine revs increase spontaniously and there is no response from accelerator. At the same time an 'engine failure' notice appears on the dashboard.
It is in the dealers for the third time snd had been there for a week and no fault has been found.
Its a 2010 petrol 1.6 littre hatchback and has done only 26000 miles. On the second visit to the dealer their computer detected a fault with a brake switch. They changed it but the fault was still there and it has been back with the dealer since Monday, 11th November.
