w221 problems.

[Ajdin1]

Hello guys, i have a W221 S class e350 petrol at my home, and i wanna clock it back from 298555 to 198555.
Digiprog 3, it writes the new value, dash goes off and on, it stays for about 5 seconds on new value, than back to original value. Anybody have some advice? Or can give me infos on that? Thanks :)

first you need make ezs, and then dash, mileage jumps from ezs

DigiProg says "Use can filter"? Anyway without canfilter. Btw First time ive enterd EZS it said "Value 7505" Days "105"
Now entered second time says "Use can filter" :s
