How can i make a retrofit Seat heat in my Freel2 working? Programming can bus ??

Assuming you've installed the seats, seat heater control module, wiring, fuses and HVAC panel then I think you will need to change the CCF to turn on the seat heating function

change the CCF...
how i can do it?

At the dealer (if it's willing) or with dealer like diagnostic tools.

So not at a dealer then

may not be possible as I seem to remember one on here finding power seats would not convert to his car having tried it FL2 MY10 TD4 GS traded in at 2 years
FL2 MY13 TD4 GS Current

Today i visit my lokal LR Dealer für programming my heatet seats in the ccf baut there is a problem. the programming needs a Passwort/code from LR to acces the programming.
The conecting the plug to my LR an read the parameters costs about 90 Euro
but my heatet seats still not work without the code

Generally dealers won't (can't) do this, the dealer tool is directly linked into JLRs server who can see everything they do with it. JLR do not support this sort of aftermarket change, so the dealer making a change without direct authority from JLR will put them at risk of liability for both any fault on your car and possibly risk their franchise. The code/password they refer to is used to enable 'engineer' mode so that all CCF parameters can be changed.

You need to find someone independent of JLR but with the dealer kit, or another way to access all data points.
