Not used car for a week and battery was flat so recharged it and on starting instead of the usual initial high idle and drop to about 7-800 rpm it stays at about 1300-1400 and driving it is rather weird as it seems to be surging a bit. Putting the aircon on high brings it more into normal.

Any ideas what might be wrong before I take it for code read etc.?

it's a 2005 2.5T with about 105,000 miles on the clock. Engine has always been faultless.
