Thats better!.It looks like the Idle Air Control Valve......and it shouldn't really be making funny noises!

Is it only making the noise with the ignition on or with the engine started?.Have you had any problems with the car stalling at all?

nope no problems at all, just opened bonnet today to hear that funny vibrating sound coming from that end, when i touched/moved that section it stopped..

the noise is only when engine is started /running..

Mmm......I'd be inclined to leave it alone.It seems to be working OK and thats the main thing.

If they begin to give trouble,they usually either bring the revs up at idle or the engine cuts out at idle.All it is is an electronic solenoid that opens and closes to allow air to pass through it when the throttle is closed to allow the engine to idle at the correct speed.New ones are around the £90 mark(thats what Peugeot charge for an identical unit,anyway) and so far I've never had to change on a Renault......yet.....although having said that,our Laguna has a tendency to idle too high when it feels the need to,so I might take mine out and have a look at it!.Sometimes they'll get deposits build up around them and it effects the seal that is made between the end of it and the seat it sits in.I've just tried mine and it is silent and it doesn't vibrate,but as long as your car is idling OK,I'd leave it be for now.:)


EDIT:A proper diagnostic test would be a good idea,but it won't often show up problems with the valve unless the ECU is getting the wrong voltage back from it.
