Can I use MQB HBA mirror to T6 PQ25 ?

[Jonp40210]

The answer is...You can but it's not easy.
I told my experience if someone want to do this
I follow this thread instructions.
The adaptions set is possible only Odis ( maybe also VCP not tested) because VCDS can't set all channels. Odis adaptation set method is different.
I use Audi A3 mirror partnumber 81A857511G rimless mirror.
So I crossflash mirror software 0010 to 0003 and then I set all the adaptation channels correct values.
Many thanks to member mmi. He give me full HBA admap. Without this retrofit would not have been possible.
When I install the mirror a new problem occured.
Audi's mirror fastening is different so I had to exchange it from old mirror. You can see the difference from the picture. Lower one is from the Audi.

You seem to know what you are talking about so I thought I'd ask a question if you have time to respond I would muchly appreciate it

I have a 6.1 E transporter that I am trying to convert to TSI from a t6

Ecu 6.1 Delphi
Ecu tsi t6 Bosch

I am told "It's not possible" to make this work as on two different platforms

But I'm not a believer of "it will never work" as anything is possible

Or am I absolutely dreaming of this conversion now that I'm 1/4 the way in

Thank you
