Tapping

[Ethan1996]

There's a tapping under my bonnet I think coming from the aux belt area? In work now so haven't had much of a chance to look but is there any common faults this could be?

I'd guess its about 1.5/2 times a second, similar to tapping your nail on a table. I don't think it gets faster when you rev the engine, certainly doesn't get any louder.

Thanks
