Experts on Bosch MED9 disabling DTC?

[rallypd]

Hello everybody, I have a 2.0tfsi 200hp engine, with ecu MED9 (MED9.1 I belive).
The car is Stock, but yesterday I installed a downpipe (It only fits the 1st Lambda (O2 sensor).
The sencondary Lambda (O2 sensor) its unplugged.

Now, I have this DTC:

000054 - Oxigen (lambda) Sensor B1 S2: Heating Circuit
P0036 - 004 - Malfunction / Open Circuit - MIL ON

I like an expert job, of course I will reward the help!

This is my file:

Thanks! Regards!
