So from what i can see when i search in here. MED9.1 bench flashing is not allowed if the ecu is not immo off. So i got the ECU immo off and i am trying to read it on the bench with a home made bench cable according to the pin out available everywhere. I can communicate with the ECU using VCDS having a lot of errors ofcause however trying with CMD it says key not present. I did a immo off using eeprom tool 2.0 and it has worked a ton of times.

Here is the log from CMD

If the ECU is out, why not BDM?

ECU more than likely has read protection on it, this is why CMD would get invalid key back.

Flash this SGO on it using CMD tool: http://odise.3110110.com/vw/1K0907115L__0030.sgo

Then you should be able to read out.

There is no protection via BDM. It's processor level flash access. You can only disable BDM by physically destroying the BDM circuitry.

I meant for OBD read.  It sounds like he is developing a protocol since he was able to write IMMO off.

I do not think you can flash an SGO file through OBD port on bench. It will not touch immo data but anyway I think that flash conditions are not met

You cannot write over IMMO data with OBD flashing.

With MED9 IMMO Off in E2P you can write on bench via OBD, you cannot start programming session if immobilizer is active.
