Mk6 R oil level sensor replacement cost?

[willsy01]

Oil light flashed orange a couple of times whilst driving today. Took it home and let it sit for a while on flat ground then checked the oil and it was low. Topped it off but the light still flashes 3 times when you turn the key to on. Book reckons the oil level sensor is borked.

What sort of coinage am I up for to have that replaced?

Edit: Just read that closing the bonnet is a trigger to clear the light once the oil has been topped off? Is there any truth in that?

OK.....you can all stop panicking. Seems closing the bonnet clears the notification.
