I replaced all my vacuum lines at lunchtime with 3mm silicone hose as a lot of them were perishing and thought this may be the cause of the problem BUT I found an end of one of them completely off! I'm not sure what it was off from, but it was the round metal thing under the TIP/N75 valve area. It must have come off when changing the TIP - Doh!
The fault took about a week to appear and 2 days after I cleared it with VAG COM. Time to clear again but doubt it will be back.
