    Default Rattling noise from 1.8 VVT.

    Dear All,

    I have a 2008 Vec 1.8 Design. Now done 19k miles. The car starts and drives perfectly with good mpg and adequate performance for what it is.

    When idling there is a slight rattling/knocking from the front of the engine. Is it something or nothing; do they all do it ?

    Any advice appreciated before i take it to a main dealer.

    Sounds ominously like it may the DMF (dual-mass flywheel). Although at 19K it really shouldn't be!

    Thanks for the quick reply, Duncan. I too hope it isn't the DMF. I have no trouble with the clutch/gearbox, selecting gears or taking off smoothly so fingers crossed on that one.

    I will add that i have only noticed the noise when the car is fully warmed up. I have never got out and checked when it has just started. Nothing can be heard from inside the car.

    So no little knock/judder when at low revs/taking off - may not be the DMF then.

    If it was DMF it would do it from cold as well, so another thing making it sound unlikely.

    Well that would definitely rule it out being the DMF then!

    I thought they were across the whole range? I wasn't sure if the 2.0T had one - until it needed replaced last year. lol

    Good trick if it is, the 1.8 doesn't have one.

    Mine's a little tappety when it's hot, and a tiny knocking when cold. Quieter than any of my previous petrol Vauxhalls, though.

    lol, well that's that one confirmed then! It'd explain why his other symptoms didn't sound DMF related.

    Must be the only one in the range that doesn't have one then?

    Yeah, amazingly the 1.8 shares a flywheel with the 1.0 3-pot, 1.2, 1.4 and 1.6 Twinport.

    Must be pretty cheap if it goes wrong then . Then again , being a non dual mass one they probably dont go wrong hey ?

    The more I see people talk about the 1.8 and 1.8VVT engine , the more I think that there is certainly less to go wrong .
