Noisy Trophy!?

[Lyles]

Hi guys, has anybody found out what this tapping is? Does anybody know if its damaging anything in any way?

I thought it was the carbon canister?

 

[Trouser]

I wouldnt' have thought the carbon cannister ticks as the rev increase. Although the only way to check is to unplug it and take it for a long drive to see if it continues. If not id suggest a sticky tappet so try an oil change if its due, possibly a PAS or aircon pump issue?

Edited to say; that is if the noise increases in frequency with revs as per original post!

Its the solenoid opening and closing on the carbon canister,this is bolted directly on to the off side front chassis and noise is transmitted into the cabin.

You could change it but it will still do it,i have some rubber grommet type things on mine and it s still noisey.if you disconnect it the noise stops.

Does it need to be connected? What's its purpose?

Dephaser pulley?

From what I understand is that it takes fuel vapours from the tank and sends it to the inlet plenum to be burnt off, something like that anyway

Its to do with legislation about not venting fuel vapours directly to atmosphere,so the carbon or charcoal acts like a sponge.
