A few updates; it's been a while but moving back to UK and working on my house has been top priority. I can however finally can see light at the end of the tunnel on the house project.
Anyway, the van has been to EcoMax Tuning in Peterborough. They did a DSG tune and a couple of other little jobs for me making the van much better to drive and more economical; No lurching from stand still, in either direction, or on a slope any more. Also, the gearbox uses the power much better and holds on to each gear for longer. It drives more like how I would drive a manual. And, to top it off, I'm getting a genuine 36 mpg instead of 28! I'm also finding the sweet spot speedwise for fuel economy now I'm doing about 300 miles a week again, so this figure will hopefully go up.
Also just got back from seeing Steve
@CRS Performance to get the H&R ARB treatment and some adjustable drop links fitted to replace the cut and welded hack job I had to settle for in Italy. Needless to say the service was excellent and the van now runs like it's on rails. Well happy!
Still loads more I'd like to do when funds permit.
