My BW34 standard spec Tornado Red GTD finally changed to 'In Transit' overnight! 
It'd previously been sat in 'Build in Progress' for 11 days with VW UK unable to confirm what was actually happening.
I placed my order back in April but my dealer reckons they've got over 70 more recent GTD orders that they just can't get confirmed build weeks for... crazy!
Looks like I am a week behind you...confirmed build week 35, but still at "build in progress"...now been a week.
Seems to be that cars are going to "in transit" 10 -14 days after intially going to "build in progress"...wait continues!
Issue I have is collection at other side of country (Scotland to Kent)...flight prices going up all the time and reluctant to book without a delivery date.
