Then key calculation

Very nice CGDI MB tool 

Many thanks for his feedback, he even promise when he has news he will post.

In addition, CGDI MB tokens:
This device also work with tokens for password online calculation
Here is info from dealer about token for CGDI MB:
free token half year, after that it is free in each day, if u calculate more, than need to charge 8usd for 30 times and 16 USD for 60times. Also all key lost need ONLY 1 token.

CGDI Benz Feedback Collection 2:

1. Generate a password in Sprinter W906 2017 year.
2. Password calculation for w212 – done.
3. CGDI reset very well BE key,BE key is after market Chinese key.
4. CGDI Mercedes Benz Programmer can work to any car FBS3. Procedure: Read EZS, choose with or without key, query for key password, save. Load dump with psw, calculation key dump, write key with unused key track.
5. W211 2004 YEAR add key ,10 min job!
6. W164 EIS type all keys lost possible only after 2009
7. I did key x164 GL 2012.
All OK.
All done in 10-12 mn.
8. Actual CGDI cannot work with old Kline ELV, only 204 207 212 ELV or emulator.
Processing, read, get erase PSW, renew. 204 need read ezs data, erase psw, and wipe ezs. After load data EZS and sync
9. Can renew ELV for w212
Yes 204 207 212, but if fatal error, not possible for now.
Need change NEC chip or use emulator

CGDI MB tested failure and explanation from CGDI engineer:
CGDI work not on all by OBD
W906 Sprinter don't work (CGDI Supports W906 only CAN BUS not K-line)
W230 SL55 AMG 2006 dont work (CGDI supports W230 CAN BUS, you can send EIS and CGDI Benz to factory to add K-line)
