it is possible to use CGDI Prog MB to renew ESL from W211, W209, W203, W210 etc?
Here’s the thing about this type of ESL:
1) CGDI renews easily those with NEC chip inside (part numbers start with 0 e.g. 0355457732). CGDI released a video on this subject recently:
2) For locks with PN starting with A203xxxxxxx it is a hc05e6 motorola inside. You can either load a virgin dump there with a programmer or renew it with CGDI but ONLY IF YOU HAVE MATCHING EIS/ECU. The trick is to copy the special key from EIS and paste it into a special key section of ESL and then query for erase password. Tested & working.
1 Follow CGDI MB software diagram to connection (W211 need gateway)
2 The OBD yellow line needs to connect the ELV plug thinnest wire
3 Read out the ELV data , Get erase password. Then erase the ELV . Get your EIS data (with your password ) into ELV. Then use your key to activate your ELV.
4 W209 and W211, W906 can sync ELV after ELV been erased. Others ELV need to get EIS data with password first , Then write into ELV.
5 If you use your key to activate your ELV , it can work. Personalized status marked , activated not marked . You can use “Activate ELV “function to make the Activated status marked.
Nec esl Vito639, Sprinter 906 renew OK.
Crafter ESL 100% NOT OK!
Some ESL must be renewed in ESL chip adapter.
