W212 ESP RPM Sensors

[Mersovod]

Try updating the ESP unit firmware. The unit version will change, and after that, additional options for changing codings sometimes appear. Also, check the coding options here. For example, W212080...2013 model year.

I updated the firmware. I coded it according to your example. There are no changes. The code is the same.
Do you have the complete coding file for the ESP 212 4MATIC for comparison?

Could this be due to a faulty sensor?
I encountered this problem on a BMW F10. I bought 3 sensors from 3 different stores.
Finally ordered the original Bosch from BMW - problem solved.

The problem was solved by correctly coding the all-wheel drive. The guys at Benzpro shared this.
Thank you all for your participation and help.
I'm attaching the correct coding for the all-wheel drive. Maybe it'll be useful to someone.
