Diags show part number 017 545 87 32 at fault, this the MSG Control unit.

Diags on ME

1444 Left temperature sensor catalytic converter

Check the voltage resistance from the right catalytic converter temperature sensor

0141 02 probe heater from 02 probe right after cat
value calculated resistance value in probe heating not ok.
0161 02 probe heating from 02 probe left after catalytic converter.
