Whistle....

....coming from under passenger side bonnet.
It only happens when warmed up and only after accelerating (take foot of go pedal and it starts) or at idle.

Any suggestions?

Maybe a leaking vac pipe does cruise work?

Late reply but only had a chance to try out cruise control yesterday.

No, it's not working.

Hi,
Replaced all my cruise control vacuum hoses from pedal to bellows with silicon hose, can't remember if it's 4or6 mm, good tight fit with no more split ends.

Well, I've found what I hope is the problem....





....now cut clean and connected.

Whistling fixed? Cruise fixed?

Unfortunately not.
The whistling was worse last night on way home. It seems to be coming more from inside under the passenger side dash.

Then this morning and all day (so far) whistling gone. But cruise still no worky.

So another pipe split? There is one that goes to the brake peddle.

As Datatek says plus check electrical connection under bellow and also the rubber bellow itself.

Being none too familiar with this, where are the bellows situated and is there a diagram to hand anywhere?

RAVE has a trouble shooting guide i believe

The bellow is the the black rubber dome where the pipes connect into, if you remove the bracket from the EAS box there is a electrical conector underneath that is worth checking, also if you suck on the rubber tube that connects to the below it should fold in if not the bellow may be split.

Once again, thanks for all the help.

Next day the whistle has gone and the cruise control is working fine.

Phucked if I know why but (as always) if it's working, leave well alone.
