Right - ours has started doing it now! Girlfriend comes in the other day says oil level warning is on. I have to say I've never used the dipstick (I know its lazy but Audis do have a mechanical level indicator). Anyway, threw in some oil from the can, didn't measure it (very lazy!) Warning light goes out. Next day she comes home its back on again. I go and check in the morning and its gone out. I'm now abit cautious as I don't want to over fill it and pull out the dipstick - no oil on it. I'm thinking this looks a bit odd, so I check in the manual and it looks like the dipstick is bust. (picture attached - can someone confirm - thanks).
So looks like a faulty switch - where is it located so I can start with cleaning it - before I order a new one.
Thanks
