BMW E46 320d DDE3 error #42 (eeprom or coding)

[elecautocr]

Hello members:

I have a problem with BMW E46 320d ECU. The car don?t start, it cranks but no start, I have error code #42 (eeprom or coding). I am attaching dumps of ECU. Can any of you check if the dumps are corrupt or checksum error ?

Thanks very much

Your ISN is: BA 79

I will try to get you another EEPROM dump, I will check your EEPROM shortly.

Please try the attached EEPROM

First read DTC and post here.

[Mr BLACK]

42 (eeprom and Codind) is main DTC ,i write eeprom 24c02 with virgin state but same error this DDE3 ecu have 2X 27C010 OTP eeproms and i think that somehow code inside is damaged or cpu is not able to read correct content, i try to read this ecu with MPPS but i only get 32K o data out of it...

The eeproms are flash not OTP. Reprogram with beeprog or similar and make virgin

[Mr BLACK]

see 27C010 datasheet they are OTP not flash

plcc32 28f010 , yesterday screwed up one dde3 with winkfp and repaired with beeprog. Original eeproms must be flash otherwise you wont be able to update software in dde, perhaps yours is first generation dde3 wich cant be updated. just gues

[Mr BLACK]

yes is a old ecu ...if is no solution , I think I'll buy a used one and program 24c02 eeprom with a virgin dump

WinkFp tips:
Uncheck option UIF Program.
Now you can program DDE/DME many times.

[Mr BLACK]

this error #42(EEprom OR Coding ) is caused from 24c02 eeprom, i reprogram a new 24c02 eeprom with a dump from D.K and error is gone but immo is active , and when I program a virgin dump configuration is missing,(eeprom OR CODING) so this error it leaves room for interpretation,

hi i have also the same erroron e46 320d 04/1999 i was trying to copy the adjustment values from another same dde done but cant start the car i draged the car with another one the car started very good working but when i tryid to restart the car no luck just smoke and nothing else so i have a file from the new ecu that i bought its similar to mine but can someone make it virgin the whole data so i can flash it with mpps so it works im not good at this type of things but i have inpa ediabas dissv44 dissv39 sss dissv55 mpps delphi ,delphi is the one who screw up ,diss v44 tryis to program it ends up with an error that cant mesure something so this is the file you guys are good at this pls help 42 DDE Error -EEPROM or Coding ;;;;;;;;;;;;;;;why i cant add the file
