Hello i have a 1.4 turbo diesel Seat arosa,
this last week there is a high pitch whistling noise when im driving over 30mph, as soon as i lift the clutch up it stops and the same with the gas,
it struggles to reach 50mph and even slows down so i have to put it in 4th gear, its usually really nippy
Some one i know recons its my turbo or i have a leak in one of my pipes
can anyone else give me a second opinion please so i can take to a garage
thanks
