A6 4F comfort trunk closing

Hi,
I am looking for a way to close the trunk by a remote and this unit 6D (4F9827851F) reject a login 12345 and also have not documented adapt.channels... Is it possible to do it also with VCDS?
I found a way in what people made it on A8 D3 with one added relay where the coil is controlled by a rear lock opening signal which grounds the button on the lid and found in WD that in this case (A6 4F avant 2008) is to the close button on the lid br/li wire and gn/gr(T10y/1) from J393 to the coil, what should be usable without any problems, am I right? I realize that the best is a relay with coil with higher resistance(lower "consumption") to make sure that there will be enough current for the lock itself, but hopefully no other risks/issues of this solution, is it right?

But if it is possible to make it via VCDS, it would be better...

Thanks for your tips,

Anybody? In newer models(VW´s, Skoda´s,...) it is usually easier and I am wondering how "sensitive" is for this connection (speaking imho mainly about "dimensioning" the output from unit and/or/maybe more about the current taken by the lock itself...) and I am thinking about check this with a scope and try if it can not affect let´s say position learning or anything else...

It is not possible to code with VCDS on a 4F - you need at least 4G to be able.

You can however buy a module at Kufatec: https://www.kufatec.com/en/all-products/comfort-tailgate-modulee-for-audi-vw-skoda-seat-33801-n

Thanks for the link... Isn´t the "module" for more than a hundred euro´s something like just say the relay I mentioned? Do you have an experince? Thanks.

Bexpro make a module for about half the price of the Kufatec. http://shop.bexpro.co/en/tailgate-m...i-a4-a6-a7-a8-q3-q5-q7-passat-3c-variant.html

Had one on my S4 for about 2 years now, works perfectly, here's a link to the thread I started when I fitted it; https://forums.ross-tech.com/showthread.php?8396-Remote-in-car-closing-of-tailgate

Thanks, why "3 on the closing switch"? (...while it´s "two wired" ... "interrupted" the br/li cable or...?) Any logic? Connection? Thanks.
Btw. done again in Superb2 with coding (remote and inside button separately), can it be done via sw update? (As in case of tail lights pre-/face...) ... Just idea...
