    Default Signum 2T Engine rattle

    Hello all hope somebody can help me out.
    Traded in my 1.8 GTS for a 2t sigum got it yesterday,super car and very fast.
    But got a problem with it i think.When moving off their is a rattling noise coming from the engine it only lasts for 1 or 2 seconds untill you get moving and then it goes,its very noticeable when say you are coming up to a yeild sign say in 3rd gear,you slow down have a quick look nothing coming put your foot down to get the speed up again and the rattle noise comes back and again only for 1 or 2 seconds.Got the exhaust checked and all ok.So i rang the dealer who i bought it from he said he knew their was a rattle from the car he said the mechanic had a look at it and said it was ok.What he did say was its just the noise from the turbo,and because i have never driven a car with a turbo i would not be use to hearing that noise.
    The problem is their are only 5 or 6 2T signums in ireland so they would not know what to be looking for, so all the help would be very useful for me and the opel dealer.Its a 2003 model with 29000 on the clock.
    Thanks

    I've not heard of this from these engines, plenty of guys on here have them as well. I'm sure one of them will be along in a bit to advise.

    Welcome to the site mate, by the way.

    Thanks ion
    Another way of describing the sound is if you took of from stand still in 2nd gear and your engine rattles just untill you get up to speed well thats the noise.

    Noise from the turbo? What a load of bollox your dealer was talking! If my turbo was rattling I'd be very worried! lol

    I know exactly what the problem is as I've had the same myself, along with a 'tweetering' noise from the engine when first started on a cold/damp day. They're caused by the same thing - although I thought the rattling noise was exhaust at first as well!! The rattling, as you say, is only apparent under load like when you slow down for a roundabout/junction and then accelerate again in the same gear - it's like a judder/rattle.

    It's the Multi-V tensioner/pulley - seems to be a common problem on the 2.0T.

    They need to replace the tensioner, and make sure they replace the pulley with the modified version (part number 93172295).

    Oh, to the site BTW!

    HTH
