After some time of waiting, it works with no other changes.
So for cars with just electric seats (no memory seats):
Address 36: Seat Mem. Drvr (J136), O7 Coding - change only Byte 2, bit 0, to 1 (or must be checked in Long codinf helper),
my previous coding: 08017025002444111000, current coding 08017125002444111000.
In MMI, Seat Adjustment you are now able to find Driver's seat, you can set Key memory on/off. Set it "on" for both keyes separetly.
Now, when you close your car, the current driver's seat position will be saved to the current key.
If you open the car, it changes the driver's seat position to the position saved to the key, when you open the driver's door.
In every key may be saved different Driver's seat position.
I don't use it every day, but I think it is usefull and, if you have VCDS (VAG-COM), it is another free mod you can have...
Hi C99, after some long time I have bought a Vagcom and started to modify my codes thanks to all your experience.
About this mode, I have tried it changing only what you said:
"Address 36: Seat Mem. Drvr (J136), O7 Coding - change only Byte 2, bit 0, to 1", and now what I have got is what you said before, it enabled Driver's seat in MMI, but my MMI said "Remote control key memory is not active", so I can not select ON or OFF for the memory key.
What do I have to do now?, because you had the same problem at first but some time later you only said that now that was working properly but you didn't say how you could get it.
Besides, I'm going to write you my car coding that it had before and after because is a bit different than yours:
previous coding: 08017025002444441000,
current coding 08017125002444441000.
As well, after doing this my driver seat rear buttons to move the driver seat to get into de rear seat doesn't work at all now (the passenger rear buttons work perfect), so I suppose I have some problem with that modified code.
I will try to code again my previous code to see if those buttons work again, but first I would like to know how did you get activate the key memory.
Thanks for all
