Hi,
Got a loud 'ticking noise' coming from the area of this valve (pls see pic) sometimes, usually when cold. It's sat next to the ABS(?) or Power steering(?) hydraulic unit on the left-hand side of the engine bay. The valve in question has a cable connector going to it with just 2 cables it looks like & also has a white arrow printed on the top of it. Please see the photo attached.
Is this normal to tick very loudly sometimes?
Under what conditions is this valve surposed to operate please?
Thanks :)

Perfectly normal its the valve for filtering fuel vapour in to the inlet to burn.
