Update firmware, and programming ?

[Tikki]

Should i take the k9 1.5 130hp automatic to citroen and update all the firmware in the cars modules?
Dont know if it could be some bug fixes that could improve the car


When pressing , and holding the lock key. The windows goes up 

On the b9 you could hold for 3sec and release th button and the windows goes up. 
Is this possible to program on the k9?

And windows roll down from the remote is this possible?

My K9 windows can be opened and shut from the fob so probably yes.
