– CGDI MB tool works good to do W207 W204 lost keys on bench.
W204 get data: About hour
PSW W204: 11minute all key lost in bench with VVDI cable

– W203 with W209 EZS all keys lost, done in the car about 70mn: Successful.
– Calculation PSW always the first time, never fail.
-Plug USB to computer, software recognizes at once. So I take 2 used BE key put in and read. Software say need 12V.
So I plug 12V and read and reset to unused quickly. Will test on bench W209 as key lost later.
– W639 super good work and super fast tested by myself on two vito 2005 and 2006
– Gateway flash/eep r/w and mileage change work only when you have other CG device.
Q: Can CGDI MB tool unlock Mercedes keys to be reused?
A: This type of MB ori keys can be unlock with adapter:
BE type china key unlock with IR.
Q: can somebody help me with my question… when built in a second hand ecu… from another came, same HW and SW… example edc16 or ME9.7…. can i adapt it through obd..?
A: Mate this tool is not made for this job. It is a good tool ( i think, i dont have it ) but for MB key making-repairing, read-write eis-ezs and jobs like this. I dont think it is good tool for reading-replacing ecus even if it has this function in SW.
Q: need to know more info about yellow cable, its to kline but where to connect it when using obdII and when using on bdm?
A: When using OBD, need disconnect ESL connector and look for Kline pin to connect Yellow clip
When using on bench: look for EZS-ELV wiring and plug the clip to kline pin
