Wanted to say thank to you guys on this forum. Went out last night (windows iced up) Tried to drop window but frozen shut. Left it until this morning then discovered one-touch open and closed had stopped working . The long key fob press comfort function also stopped working. Tried sorting via Carista..no joy. So then I start searching on T6 forum. Did the down and hold for 10secs and up for 10secs routine. That worked on the drivers door but still no one touch function on passenger door nor the the key for comfort open/close function. The saw a comment saying take the van for a short drive. Was puzzled by that suggestion...but that worked!! You guys on here rock..Thanks!!
