Precat o2 sensor c350 cdi

[affalterbach]

Hi
Does anyone know what the mb part number is for the precat o2/lambda sensor on a w204 c350cdi ?
I’ve got an error saying
“The signal from oxygen sensor1 (cylinder bank1) is shifted towards rich”

I initially cleared the error and it has now come back. I was going to just clean it up but just makes sense to replace after removal.
