Title: MED9.1 Bench flashing - Did a search Post by: jastr on December 11, 2017, 02:34:35 PM 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.

Title: Re: MED9.1 Bench flashing - Did a search Post by: superglitch on December 13, 2017, 11:54:47 AM 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.

You can only disable BDM by physically destroying the BDM circuitry.

Or will it keep immo data if i flash some other ecu with this flash file?

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