I’ve just swapped my T6 electric/heated mirrors to power folding mirrors. And they fold on remote lock 
This approach requires you have the standard electric/heated mirrors. Part of the kit would apply to add fold/unfold on remote lock/unlock to factory installed power fold mirrors - see my comments at the end.
The 2010+ T5 mirrors are the same fit so I got the mirrors plus control kit from Travelin-Lite on eBay, minus their T5 door switch. The OEM T6 door switch came from my local dealer.
The job involves removing all the lower dash trim and door cards, and swapping aerials (four!) from the old mirror bodies to the new mirror bodies. The most delicate part is swapping over the mirror caps...
Wiring colours were the same on my T6 as the T5 instructions so that helps Main differences to the T5 instructions were trim removal and finding a location for the unit along with suitable power feeds. I can post more install info if requested.
No coding is needed for the mirrors. But avoid disconnecting the passenger airbag switch when you remove the LHS trim otherwise you will get an airbag fault that will need clearing.
I made a couple of mods to the control unit to park the passenger side hard to a wall with mirrors folded, so that the mirrors don’t unfold until I switch them Folding on remote lock is great though
If you already have factory power fold mirrors then I think you should only need a reduced number of kit parts that would sit between the fold/unfold power pulse from your control unit and the feed to the mirrors. I’ve seen this part referred to positively for a T5 fit and it looks similar to the heart of the kit I bought. The lock/unlock pulse can be picked up behind the driver’s door card if not found in a more convenient location. Best to find the factory fitted fold control unit and identify the switched fold/unfold +ve pulse there (maybe behind the RHS lower dash trim?). Otherwise you’ll have to remove both door trims to break into left and right separately, and use more cable.
