I can only speak for myself, but the answer for me would be, don't do it.
Unless you can do most if not all the mechanical work yourself, I believe you are opening yourself to a world of financial pain and potentially the inconvenience of unreliability.
Yes they do drive beautifully.
And what other options are there if you want a AWD van.
And this thread here about one is fantastic;
And so it starts.....my new T5 LWB Motion
I had been looking to do something similar.
I already have all the running gear from a 2010 low km single turbo, I really liked the sound of an AWD van and I too have a well regarded VW mechanic.
Have found a couple of 2010-2012's with failed mechanicals, but his advice to me has consistently been...don't do it...it's too much work...and I would be paying him to do the work.
He says all the wiring looms need to be replaced and more. I don't know if that's really the case. I couldn't verify it. But it was enough to put me off.
The UK forums have a lot more info as there are a lot more vehicles.
However I was not able to find anyone who specifically went from a bi-turbo to single turbo back when I last looked.
