Hi.
Got interesting situation.

In theory usual all keys lost.
3.0D cas3+ encrypted
Readed cas and 95640 from ecu. Key made ok with loaded dumps. When put in car . Dash totaly dead .
Can anyone confirm if put wrong key on dash must appear key error that its recognized +gong sound ?

Cas readed with vvdi key made with tango.
I

Dumps will upload here tomorow. But about that not appearing error on dash.

Also when opened cas i see someone was here alreasy visible soldering points.
Also owner said he broke window to get in the car. I know bmw is deadlock imposible to open car from inside
if window is broken.

So you got ISN from ECU.

ISTA P ?
You write back new file to CAS?
Or only generate and test in vehicle.
Write key to new key point, or old key point?

If you did not write back to CAS
Can you test generate with VVDI2 in a new key point.
And not write back to CAS, if it is ISTAP.

Not isn. I loaded whole 95640 eeprom
dump accepted and key made. Dump with new key wrote back. Position unused.

with vvdi2 its saus encrypted version and asks same as tango . Isn or ecu dump.

maybe need read ecu eeprom by bdm? Now i readed it direct from eeprom as it was visible near mpc55...

Maybe its accepts dump but not find correct isn

Check if the key ID is already used at a different position, it wouldn't surprise me if the Chinese keys have a very limited set of IDs. If the key ID is already present at a different position, it won't work.
By the way, completely wrong key (e.g. wrong car) will not do anything.
