Alright guys, spoke to VW UK this morning and they've told me by provisional BW has come forward to 37. He said it came forward from 38 a while back and has stayed static since. So i'm pretty confident that this will become confirmed in a couple of weeks. The nice chappy said the same also.
Anyway - He couldn't be 100% sure that i'd still be able to add spec at this stage, but did mention if I did it 'could' push the BW back.
At this point I just got too frightened to consider this possibility, threw my phone against the wall and then ran around the office flapping my arms about. Well not quite, I politely thanked him and finished the conversation.
