Audi A3 8P - 8P0920930T bench pinout no comm

[Juppie902]

So I have a replacement dashboard for customer A3, uses x2 fujitsu mb91f366gb, 93lc86c
its a 2007 (b7) (original dashboard: 8P0920931B , cdc32xx + 24c32 with immo error)
Customer brought this used dash that I try to connect on bench using a DIY K Line from my china KKL vag commander cable, but I cannot communicate over K line. via connecting CAN Hi + Lo cables = works.
attached pinout I used (confirmed with ELSA, correct pins for original dashboard)
also text pinout:

BLUE SINGLE CONNECTOR
PIN
1 +12V
2 +12V
3 GND
4 GND
5 K-LINE
18 +12V
19 GND
29 CANBUS LOW
30 CANBUS HIGH

ON OBD CONNECTOR
PIN
16 +12V
4, 5 GND (USE BOTH OR JUST ONE)
7 K-LINE

I get 9v on K-Line without any communication, not sure if its good or bad? dash itself does not light up only hear a click when power on. Noticed something strange, on OBD connector pin 7 (K-line) is also connected wth pin 4 (Lin bus) all the time, but I did not wire pin 4.

I want to pull PIN for coding it in customer car (dont have VVDI or any other good prog for FLASH, only xp400 is not enough), have VAG commander, VAG EEPROM editor, VCDS.

also a problem, if anybody has the similar dashboard 8p0 920 930 , PLEASE UPLOAD PHOTO OF PCB, FOCUSED ON THE 2 MCU's
I think I moved a resistor or two when I re-soldered back the top MCU (top = when dashboard facing up like normal in car)
attached photo of suspect damage.
