Hi,
Just to close the case:
The root cause was my failed trial of bridging the brake pad warning permanently directly in the wiring harness with a jump wire. After the wire was removed everything started to work again.
Big thanks for Stefan for great support! 
Hi,
I'm located in Helsinki Finland.
We can continue in email for more details.
Thank you!
Please find a photo of the wiring as attached.
Meanwhile I deleted and re-flashed the firmware, but the same situation remains.
There is an external oil pressure sensor connected to analog input 5. Is it possible that it could cause issues? I will try by disconnecting it in couple of days anyways.
Thank you for quick responses!
I measured pin B1 with multimeter and it shows 0,8 Ohm to pin 7 of the green connector counted from the direction of red arrow in the attached image. All wires and connectors look ok with eyeballing method.
Checked once again that ECU INFO gives still the same error message.
Hi,
Nothing plugged in the OBD-socket.
I did what you suggested, but when going to Ecu info it just gives the warning: OBD-ERROR, Communication with control module failed.
Hi,
I got FIS-control about 2 months ago (Audi A4 B6 2004 with color DIS). First it was working perfectly, then gradually communication problems became more and more frequent. Now I cannot connect to any control module. FIS-control menu is available normally and I can connect to FIS-control via Android app as well. I have the latest firmware 2022-12-24 installed and all the wires are connected correctly.
Tried so far:
- Through the Android app both Telematics and Navigation as communication method - no success
- Erased all the settings - no success
Do you have any idea what is causing the issue?
Thank you!
