How to read ISN of EDC16c35 (for example in encrypted CAS3 + when all keys are lost)? An increasing number of locksmiths verified CGDI Yes, Autohex Yes, VVDI No.
Autohex: Yes, but not on bench
Tried ISN extraction via ON-BENCH, didn’t work
Finally succeeded with the following steps:
-> copy content of 96540 eeprom of original-ECU to donor-ecu
-> coded the donor-ecu to the car
-> updated the software of the donor-ecu
-> EWS alignment
CGDI BMW programmer: Yes
Oh I surprised, I can read ISN of EDC16c35 right with CGDI and AVDI but not change.
Path:
Open CGDI software -> select “BMW ISN Read Write” -> select ECU type -> click on “Read DME ISN” and then after it succeed, click on “Write DME ISN”.
It’s nice feature is it come with wiring diagram.
Good to know:
CGDI BMW programmer wins in ISN reading /writing for a wide range of DME. And it is available with individual BMW ISN reading authorization.
Xhorse VVD2: Failed
I bought Xhorse VVDI2 new, can‘t read ISN of EDC16c35 . Not on bench not in car.
I think VVDI II cannot read 2 bytes ISN.
Path: open VVDI2 Quick Start -> BMW -> Key Learn -> ECU/CAS ISN -> Type E-Series ISN -EDC16xx.
No matter what you select “Diagram”, “Read ECU information”, “Read ECU ISN”, it will pop up not supported yet or failed. But software prompts it will add this type in the feature.
Hope it helps!
