Have just taken my car to main dealer for service. Have had 2 problems with car whistling noise from engine on accelerating and intermittent starting. I do not have starting problems every day Garage tells me I need a new turbo at a cost of £750 and a new starter motor. The car has only done 39000 miles. Do you think the garage wants to make extra money from me re complete replacement of parts or would I be better getting second opinion?. Apart from the whistling the car drives well and the whistling does not affect performance
