All components come from the same donor
building a test platform for the Audi A4 B8. I have collected ELV(j764), BCM2(j393), Gateway(j533), Instruments(j285), Bcm1(j519) and E415 key switch.
All components come from the same donor.
My connections look like this:

ELV
pin 1----> Bcm2 t32d pin 15
pin 2----> Bcm1 t32a pin 26
pin 3----> (+)
pin 4----> Bcm2 t17p pin 15
pin 5----> Bcm2 (LIN) t32c pin 17
pin 5----> E415 (LIN) pin 7
pin 6----> GND


INSTRUMENTS

pin 29,30 -->GND
pin 31,32-->(+)

GATAWAY

pin 1----> (+)
pin 14---> terminal 15 (not connected)
pin 11---> GND
pin 8----> Can L instruments pin 3
pin 18----> Can H instruments pin 4
pin 5----> Can L BCM2 pin 5
pin 15---> Can H BCM2 pin 15
pin 5----> Can L BCM1 t16b pin 14
pin 15---> Can H BCM1 t16b pin 15
pin 9 ----> Can L OBD2
pin19 ---> Can H OBD2

E415

pin 5----> BCM2 t32d pin 11
pin 6----> BCM2 t32d pin 12
pin 13----> BCM2 t32d pin 20
pin 14---> BCM2 t32d pin 13
pin 15----> BCM2 t32c pin 3
pin 7----> LIN BCM2 t32c pin 17
pin 7---->LIN ELV pin 5
pin 8----> (+)
pin 16---> GND

BCM1

pin 16 (t32b)----(+)
pin 16 (t17I)-----(+)
pin 16 (t17m)----(+)
pin 16 (t17n)-----(+)

pin 17 (t17o)----GND

pin 19 (t32c) ------> Can L
pin 20 (t32c)-------> Can H.


I have adopted the key and connection to each module.The remote control works, the instruments start after inserting the key into the ignition.
I only have a problem with the ELV steering lock.
No reaction after inserting the key.
I insert and remove the key but the ELV does not open or close.

There is constant communication with the ELV. No errors in modules 05 and 46.
