VAG EDC17C46 can't read in boot mode

[ignac112]

Hello. I need read eeprom from this ecu, but I can't connect. In obd I can flash via mpps, kess, odis, vcp, but in boot mode ecu don't recognize by mpps, k-tag, v54 and x-prog. By k-tag i try use 199 and 268 but tool say "Micro protecion removal failed ", galetto recognise ecu but can't read eeprom and flash, another prog don't see ecu. I try connect with 1k Ohm resistance but nothing happened.

Do you have any idea?

How many boot pins are you using?
There are 2 diferent connections:

Try this on ktag if you have "Micro protection failed" error

Did that actually solve your problem? On my ktag clone that bridge is already on the PCB. And when i faced "Micro protection removal!" warning was always because of wrong protocol selected.

The bridge solved my problem
