Mileage is in PDM (passenger doormodule) and DDM (driver doormodule), you have to change km in these units (eprom) or erase eprom (not flash!).

I try to read/write with X-Prog but with 8mhz after connected to mcu give an error, (device silent). Is there any trick for read write ?

No :-(
But i think reading is not possible with xprog. Maybe just writing is possible but you need to have a good known 0km files for write back.
If you find some let better option please let us know.

yes, but if car updated to last firmware version NEC become Locked, as in Audi BCM.
No possible to read or write. At Audi BCM nec can be erased, and only after write. And in locked state no possible reading.

Dash-CEM sync value stay on dash firmware or in CEM firmware?
Which one will be patched ? Dash or CEM ?
