I've got a mk4 150 diesel, it's on 112,000 miles. Last week the car decided now to give me any power on the motorway when I went for a pretty normal overtake. Driving home the other day and I get the dreaded 'Emissions workshop' alert, to cut a long story short the fault code was for 'Turbo over boost'.
I have spoken to a mechanic and he said the turbo is knackered and I won't be seeing much change out of £1,000 to have it repaired
Has anyone had this happen or had replaced their turbo? What sort of cost is average?
