i have 2013 bmw 640i grand coupe that i have error on the left rear shock dumper saying :
"when the damper satellite has clocked up a kilometer reading of more than 50,000 km,both dumper satellites on that axle must be replaced "
this message coming from Ista-D .

any idea how i can reset the miles or kilometer for the damper 

this is 2 pictures showing the message and what's the damper .
 
hope someone know how to get it done

That notice is simply telling you that the dampers should be replaced as a pair if they have more than 50,000km. If you have a problem that requires changing out a damper, it's asking you to change both. It's like changing a broken strut, you should replace at least the pair of them if they have high mileage on them. You don't want one brand new strut next to a heavily worn one. 
I'm almost certain that there's no odometer function preventing you from replacing just one.

Out of curiousity, was this vehicle in an accident? I'm chasing a missing satellite damper code on a wrecked F02 at the moment.

i know what it says , i just don't want to replace it since user is 250$ plus label and maybe i'll be having same issue with the used one .
yes,it was but drives normal !

It's not telling you that it needs to be changed based on mileage alone. It doesn't track mileage and command a replacement at 50,000km. It's saying that if you need to replace one, do the pair if they have more than 50,000km.
What code are you seeing? Have you checked all the wires for continuity? Are all Flexray modules present and functioning?

[mmauto01]

D66D61 : EDCSHL interface (damper satellite, rear left , 1.o.1 ) signal invalid
481342  : EDCSHL internal control-unit  fault

those are the code for it and i didn't check the wire because with istad it's saying the unit is fine and but i will eventually

[RocketSurgeon]

I would try programming and encoding that damper, you might get lucky. That second code isn't looking good though.

Check wiring first, much more often there is the problem, not the shock absorber

[mmauto01]

i will be checking it soon 
we had to fix the airbag headrest error and should be in shop soon .

Speacially connetor pushed right to the end!. I lvery often looks it is ok, but simply dragging it out confirms iif it is locked or not
