    Default CDTi 150 Turbo issue !!

    Havent long had my vec !!!

    First problem, sort of lol

    Drives fine, sounds sweet with no warnings but I put my foot down today and it didnt feel as quick. Ive messed about with it, and found that...

    Bear with me, as you accelerate, you can hear the turbo spool up and you can hear it die out where the most power would normally come in and the sound it makes when you back off (wastegate ??) isnt as harsh as it was ???

    It still pulls very well, but not like it did before !! Any ideas ??

    Thanks !!

    By the way, 2008 Vec, 15,000 miles !

    Ive had a scenario with mine, where the Turbo spools up, and for a split second the power backs away, and then picks back up again. (Usually in 2nd or 3rd gear)

    I gave it a good "throat clearance" when the engine was at temp, and its been fine since

    Yer, sounds similar - it spools up, then you hear it back off where the full power would come. It doesnt pick back up though.

    Will give a good boot ago, cant do no harm !! lol

    Swirl flaps or EGR valve.

    If the turbos is whirring then it is fine m8.

    If either between the swirl flaps and turbo i hope its the turbo.
