Found some had trouble in reading ME7 by his ECU device. Here is my experience of reading ME7.5 with my ECU tool KTAG master. Hope it would helps.
My KTAG ksuite firmware 6.070 ecu programmer source:
i just tried to read ME7.5 with K-tag, everything good !
ME7 boot pin
ME7 pin out
Pin 3,62 – red – +12V
Pin 2 – black – ground
Pin 43 – yellow – K-Line
Soldered wire – gray with alligator clip – BOOT
ME7 Protocol selection
Select BOOTLOADER ST 10FXXX>>BOSCH ME7.5 VAG HW II
ME7.5 full files
ME7.5 full read
And i found there is problem with Ktag 6.070 while selecting cars family:
If i try to read with cars family, it won’t read;
But, if i select Protocol and get the correct family. it read perfectly well!
