    Stange noise 1.7 DTI Van ?

    Ok,

    This has only happeded three maybe four times.

    When im tootling along in 5th gear at about 2500 3000 revs on say a motorway sometimes I get TSSSSSCHHHHHHHHH from the engine bay like somethings going faster than the revs

    It sounds like (and I dont know) but if I was to guess the turbo spinning and not releasing like its spinning to max and not releasing. If I press the clutch in or drop below 2000 revs this normally then stops. Incidently my turbo kicks in at 2000 which is why I think it may be that and ive never had a non aspirated engine make this noise.

    Dont get me wrong it only does it a few times its not like every day but its is concerning.

    Thanks chaps,

    Luke.

    Tootling in 5th at 3000rpm is about 85 Wouldn't like to see you in a hurry.

    Could be the EGR playing silly beggars. Might be worth checking to see if the EGR is seated properly.

    haha I once had a 1.3 astravan on an A reg but it did go well. Funny thing was I was charging up the M56 at 110 behind a Porsche in the outside lane and the Mrs's dad was in the slow lane doing about 50.

    When I got home he said, "I was driving along admiring the scenery and this red blur went past like a spaceship" lol so I promptly replied, "There were arrows on the road and I had to keep two chevrons behind the car in front!"

    Anyways the noise sounds like something is stuck as when I take my foot off the gas its still there untill I drop below 2000 revs? I have fitted an induction kit so it may be that perhaps just wondered if it was on the way out the turbo?
