    Vehicle : Vectra c SRI Facelift

    Trim : SRI

    Engine : 1.9 CDTI 150

    Year : 2006

    Default Worried about strange noise

    On thursday i took advantage of the nice weather and had a tinker undee the bonnet.My EGR valve was due for a clean so i took it off and seperated it and knocked out the solonoid and soaked it in carb cleaner for 30 mins.While it was soaking i sprayed some carb cleaner into the hole where the EGR valve goes as it was very sooted up and scraped out as much as i could.

    After putting the EGR back together and putting it back on the car i then started the engine and sprayed 4/5 squirts of carb cleaner down into the air intake(avoiding the MAF sensor) while my mate held the revs at 2000rpm.There was a tiny bit of smoke and thats was it.

    Now when i drive the car and acellorate over 2000rpm theres a high pitched squeeling noise,sounds a bit like squeeling brakes and will continue untill i ease off a bit.If i rev the car when its stationary it doesnt make the noise.

    Its definatly not the aux belt slipping and i dont think its the turbo as the car runs like a dread and has masses of power and no smoke.

    The car is a 06 vectra facelift 1.9cdti 150

    has anybody got any ideas when it could be?
