I have got troubles with INPA on my pre-LCI 2005 BMW E60 530d. It wont access any module, just keeps saying "IFH-0003 Data transmission to interface disturbed" But I see ignition & power in inpa screen

However, on my 2003 BMW E39 525d everything works great.
What could be the issue? I have no idea what to look for, as the cable seems to work on other car, so why not on E60? I googled that the E60 and E39 should both use the same protocol (KLINE), DCAN is only for cars from 2008, so communication protocol shouldn't be the problem.

I have soldered pin 7-8 and my cable looks similar to this: https://i.ebayimg.com/images/g/gpoAA...-b/s-l1600.jpg

Thank you for any help, i'm lost!
