KTag EDC17C74 not identifying/reading ECU

[mttlr]

Hello guys,


i have a 2018 golf mk7.5 gtd dsg DGCA with a Bosch EDC17C74 (04L 907 309 R) (0 281 031 66) and i'm using Ktag 7.020 Red with SW V2.25. Unfortunately, Ktag cant read anything from this ECU. I use protocol and pinout 705 (boot pin with probe pen and bdm frame) and it doesen't even identify it, always ending up in a communication error.


The ECU is still working like a charm in my car after opening.


I already checked:

• GPT Cable pinout is correct
• D-SUB Cable pinout is correct
• tried powering ECU via KTAG with 12V 1A, 12V 1,5A, 12V 3,0A
• tried powering ECU with external 12V power supply
• tried different pinout found in the internet by dimsport where CAN-HI and -LO go to pin 51 and 52

When getting ID with Kess, it shows:
HW Ver. 04L907309R
Upg. SW 04L906026RK 7727
Engine R4 2.0l TDI


I also already tried reading it with a friends Ktag (also red, same versions) and its also not working / identifying.


I already searched the whole internet for days and i'am despairing...
Do you guys have another suggestions or things i could try to make it work?
