Like someone lightly thumping on something not banging,only happened twice so can`t really tell where from,happened today and about 2 months ago,almost like someone is locked  under the bonnet and is tapping to get out,in a perfect rythm .(and no before anyone says it  :grin:)

Might be an aux water pump or valve shutting down.
