Checked the header tank and sure enough there is a jet of water recirculating into the tank.
Cheers again for everyones help!
Also, my parking sensor turned up yesterday, ordered from the same link as garioch had posted. Seems all good, just need to get the bumper off in the next few weeks and get it changed over.
Next job is sorting the auto folding mirror that doesn't want to stay folded in! Always seems to be something to do with these cars!
