Hey there!

I have a BMW X6 E71 40d
I first got a Kess v2 Clone, while trying to read using P221 protocol (first did OBD II Unlock), I got Comunication line not present or interrupted. If I selected CP02 or any other Tricore I would get wether Micro WakeUp error or Micro Unprotection Failed.
Then, I thought it would be Kess issue. Then, I bought K-Tag 7.020
Tried both 667 with GPT direct connection to pins 19 and 22, and without and P221 no GPT. Gotta say, if I select P667, the HW gets faked and it is wrong, on P221 it matches with OBD II Data from Kess. Also, KTAG says to read ECU ID through OBD first, but I got no adaptor KTAG-OBD, then I did OBD II Data again with Kess v2. Repeated process and still no luck. Also reinstalled K-Suite v2.23 and no luck...


On both P221 and P667 I can read EEPROM, I get the file, but not Micro, where it will do:

Identifying ECU ...
Reading device info ...
Reading backup ...
Reading Micro ...
SECTOR: 0x00000000
Error in reading

Do anyone have any idea?

Thanks!

PS: I think car has some sort of protection on file, since it was tuned.

Must be ISTA-P or WinKFP will do the job since it is E71?
