Clicking noise when tapping accelerator gently when idling

[Thrill]

If I tap the accelerator ever so slightly while idling the car clicks (when the engines running and I'm idling) is this normal? It's coming from the drivers side corner of the car. Can hear it more from inside the car than outside the car for some reason (I havent had chance to open the bonnet and do it to see if you can hear it more from there). The noise speeds up when you tap the accelerator more, then the engine wines and then goes away. Can also hear the clicking when I'm in lets say 4th gear but only doing 20mph (basically, going too slow for the gear) I've uploaded a sound clip, heres the link:

The noise kinda sounds like a relay clicking tbh, but its on the right side. I just hope it's nothing in the engine or valves or anything. The cambelt timing is fine, it's been timed by a specialist, had a new water pump too plus aux kit. It's well looked after! If anyone knows what it is then please say

Slipping fan belt maybe? Mine did something similar on a cold winter night.

Sounds like it might be your carbon canister. Put your head by the drives headlight and it should be loudest there
