Welcome to the forum dentist.
When I first read this I was curious as to whether it might be linked to a blocked particulate trap, with a vague translation to English.
I've heard of clogged DPF being a problem on lots of cars (Renault especially?), but not read of any MBs on this forum being affected - or at least I can't recall it.
Ah, a good point BD, forgot about that.. There has been some issues with the gel coating of the sensor getting dirty and flagging up the code.
A modified sensor has been released as a result.
