I have ordered the winter pack also with cloth seats. I looked on VW configurator today to check if it is still available with cloth seats. It seems there are 2 options. Winter Pack with Leather and just plain old Winter Pack. So it seems you can get Winter Pack still with Cloth Seats.
They really need to set in stone the options available in the UK and leave it at that. Things keep changing all the time, I haven't even got my car yet.
I am still on Build Week 34. The week has not budged in a while since I was initially told Week 22 a month or two ago, so fingers crossed it stays at Week 34 or moves to an earlier date which I doubt.
