I have dual Lambda option and i use Bosch 4.2 sensors(0258007059)
My problem is that only one Sensor is working, no matter if LA1 or LA2
If i connect a sensor to LA1 it is working
If i connect a sensor to LA2 it is working
If i connect both sensors only one sensor is working.
I changed several brand new lambdasensors.

WTF i found it....my mistake
AUX1 and AUX2 are crossed in the wiring.
I changed it and now everything is working
