mercedes R230 2003
Hi this is the 2nd attempt and second used unit i have bought to try to sort this out,
any input is appreciated
from the original eis i red both muc chips 4j74y mask (r1 and r2) both chips and saved the bin files , ie eeprom and both flash files
i still got these bin files just in case.
with R270+ we then transferred the bin files over to the used unit chips again they were 4j74y chips (same as original unit,
all seemed to go well, the car started the original keys worked the car drove ok and locked etc, (but when we went into the car with mb start and autologic just to see if there were and issues because the roof would not work,
and we could see there was about 4 - 5 ecus not being seen on the can link, and the replaced eis was not seen in the unit list,
so we have bought another unit,
the original eis unit part number is 2305452308
the replacement used one i have just bought is 2305450508
so what the best way to go again, thanks all
