Could there be a bug in the current version?
MKB: BCB
Label file: RKS\036-906-034-AZD.lbl
Control unit part number: 036 906 034 DR.

"I am seeing the following:"
Lambda control (oxygen sensor status).
Bank 1, Probe 1, 000.
Bank 1, Probe 2, 100.
and after about 1 minute.
Bank 1, Probe 2, 110.

Normally, probe 1 is the upstream probe and probe 2 is the downstream probe.

However, the upstream oxygen sensor is initially activated at 100 degrees Celsius at engine start and then at 110 degrees Celsius after 1 minute, while the downstream oxygen sensor is only activated much later. Or have I made a mistake in my thinking?

Thanks for the feedback! I will forward it for review. Please also provide the VAG part number for the engine control unit.

Best regards, Rainer.

I have edited the text above.

Normally, probe 1 is the pre-catalyst, and probe 2 is the post-catalyst.

Okay, just disconnect the cable from the respective probe and see what happens.
