2005 E60 diesel battery drained . They tried to start the car with drained battery few times then ignition on and powered battery with extra charger and tried agan till killed the DME eeprom .

DDE is function properly with all engine sensor ,all live data parameters ok .but cant recognize CAS . ( error ews manipulation ) .
Resynch in CAS function CAS/DDE .says ok but usless, car dont start because DDE eprom ISN its not anymore .

DDE reflashed, VIN ok ,cas recoded all car but still same problem.

I have atached eeprom DDE + eeprom CAS , if someone can help extract ISN from CAS and write it back into engine eeprom.
..

It is not the same. All the time engine get EWS MANIPULATION, and CAS no . Synch in CAS work, in DDE no. . .. DDE is original of car.

hallo ....i have a similar problem with a bmw 525 E60 2005 ....DDE/ CAS sync fails ..and a dde have a error : internal 4 ( Fault when reading from eeprom )
and it was caused from a battery fail ...i can adopt your solution cipijoint ? or only solution is to change ecu

thx

EEPROM corrupt mean need to replace data inside EEPROM with good!! After this change ISN to match old and then start car. EASY!

what tool have you all used that got that errors? Isn go corrupt sometimes. Eeprom is inside MCP555 , not external eprom. need read via BDM
