Title: ME7.5 After IMMO OFF no response
Post by: OberlandRacing on January 23, 2021, 09:30:58 AM
Hello, i have an Me7.5 1.8T ECU and i changed the IMMO via "ME7EEPROM Tool & EEPROMTOOL04"
The ECU Starts in Bootmode and i can read the Flash.
I can also write the ECU but MPPS gets no connection without Bootmode.
I also changed the IMMO back to Original and the Flash.

Bootmode works fine, just get no answer after all of this.
maybe someone has a Idea.
Thanks.

ether the files you have are someone else's and they have some kind of custom code for security, you used the wrong protocol to read and or write and the eeprom is corrupt as the end result, you didn't correct checksums, or you shorted out the ecu. considering you said it still goes into bootmode i doubt its fried fwiw.

Mhm, the EEPROM is still Write and Readable. Also the Flash. Checksums checked. Also the Stock File from the ECU does nothing.

How coud i kill the ecu?

I will do tomorrow.
Thanks!
Did you find anything "special" in my EEPROM?

It also dont worked with your File.
Still cant get connection to the ecu.
Maybe i killed the EEPROM with the wrong Checksum? But i cant believe that.
I Mmade another file with the original EEPROM File, that shoud work.

I also tryed Immo On/Off.
With other Flashes i have the Problem that they Fail. Just the Stock one works..

I`ve tested many EEPROM Files.
With the EEPROM Tool i checked every File for Checksum.
Also i checked the Flash.bin for checksum.
ECU gets wthout any Problems in Bootmode.
But MPPS cant get a connection. But before i played with IMMO it worked. It was the first ECU that i played with Immo.
Just the first File had bad checksum because i forget to fix it. (--fixcs)

So i will throw it in the car and test it.
