Its a 2.2DTI 2002 Vectra SRI Hatchback with 92k miles.
I've had the veccy nearly two years and have gotten to know it quite well now. Last week I put my foot down and was greeted with the turbo spooling up with a loud whine. It does it in all gears. There is no loss in performance and there is no smoke.
Under acceleration whine spools up with the turbo then flattens off about 3,200 rpm whilst the car still carrys on accelerating as normal
Its not a whistle which indicates a split hose. Have checked all the hoses just in case though.
I had a turbo go on my megane and it was a scrapping noise not a whine so not really sure whats going on.
has anyone had their turbo whine go loud for no reason?
Things that have been done in the last 2 months:
Oil catch tank fitted (now put back to standard in case it was causing issue)
Full service including engine flush
New oil and fuel filter
Gear box oil changed
Any ideas would be great!!!!
