W204 ESL with new nec

[Perryking]

Hi, If I want to repair W204 ESL with new motor and nec, how to program this nec? Because after change chip, I read ESL with VVDI MB and is empty. So next step is the same like adapt used ESL to original EZS? Have VVDI MB and IM508+XP400

Never done it with new nec, but... i asume that it is same as emulator... VVDI MB -> calculate password -> read EZS -> calculate erase password -> save file -> erase EZS via IR -> WRITE VIN (OBD) -> Write EZS from file (IR) -> Activate ESL

What do you mean read empty ?

Do you have current EIS data with key password saved ?
then write it to ESL, insert key, see if it can activate.

Yes, I mean on bench obd mode with vvdi mb, just after place new nec, I read ESL and all info is empty. I think the way is like emulator but didnt try yet.

empty, do you mean all "00" or "FF" ?
as it is new chip maybe nothing,
if the status is not activated then just write EIS data into it.

The seller site should have instruction about it.
- read ESL with that NEC chip
- if it is activated, erase with pass 1111111111111111
- read EIS paste key password, save EIS data
- load EIS data, write to ESL
- done

Recently I had to replace ESL from W204 and I bought used one. So did the job and car goes, then I take the old one damage, and buy new motor and new nec (for next customer). At this point I dont have anymore keys and EZS. So change nec, connect only ESL with new nec to VVDI MB and all data is empty, but vvdimb says ESL is on good condition. So new nec dont have any kind of data when is new. I didnt try to read this new nec on adapter, just solder to ESL and read obd. Until I dont get the next customer with ESL problem, I cant try if works the same like adapt used one or like adapt emulator.

Only ask for know how to do when need.
