thanks you,
just one question, i see there ist the MAC different (Master/slave). Is this OK? (ecause the engin wil not start)

[Jancis]

what say diagnostic ?

[Pali33]

unfortunately, i don't have the car here. Only ECUs .
It is just interesting, that the two MAC in Master/Slave ECU not same are. I thing, PIN MAC and CS should be the same in boths ECUs (master/slave). But i have no experience with MAC and CS codes.
Who can confirm this?

[Jancis]

Master and Slave ECU have always the same flash content!

[Pali33]

yes, this true. But the security codes (PIN,MAC,CS) are in eeprom and eeprom is different in master and slave ECU.
My question is: should PIN,MAC,CS be the same in master and slave ECU?
