Have you seen this?

Elsewhere on the internet, there are various posts that VW recommend just to clear it if it's the only engine management fault code. Another source has had a similar issue (where both sensor 1 and 2 were at fault) and a new EGR cleared the problem. You could probably spend ages chasing it
