Certain components have the following note in EPC:
672 Part must be checked after installation for current flashware

This is the case for the Distronic/Blind spot radar sensors.

On control units, this would make sense, but parts such as radar sensors...
How or where do you check the flashware, and update if necessary?

I'm asking, because I am not able to communicate with some blind spot sensors, which also have the Distronic compatibility.
I wonder if "not being able to communicate" means no ability to connect at all, or they "speak a different language", meaning it could be corrected by flashing it?

For Distronic, the sensors are connected to the Distronic control module.
If using blind spot, there is no other module, the sensors are connected directly to front SAM, on CAN G.

I was hoping that I could get the Distronic + blind spot sensors, and use them as Blind spot, for now, connected to front SAM, and use the same sensors later, when I will be retrofitting distronic as well.

I have obviously checked the wiring harness for 12V; and continuity on the CAN wires, before posting this.

I have done SCN coding on front SAM, instrument cluster, cgw, left and right door control modules.

I am currently getting an error in the instrument cluster, and door control modules, saying "Missing message, from CGW" and I am unable to communicate with the radar sensors.

The door control modules are responsive, and I am able to actuate the triangle in the mirror glasses.

Doing this retrofit on my own 2011 SLK R172.

Any input is greatly appreciated!

My issue was the radar sensors.
Now that I replaced them with sensors that do not support distronic, it works.
