Yeh vagcom or a suitable scanner can help in these situations, you could try puting out a shout for someone in your area, I think there's a big list on the tdiclub for who's got what and their location. I've also got an autel vag405 scanner that works on just about all the vags, really good piece of kit, the latest fault I found and cleared was on a 2008 tdi. You can pick them up on ebay.
