I have a 2004 bmw 3 series 330 I believe it to be e46 . I have only done 7 series e65 styles. I have access to digiprog datasmart 3 clone, obdstar x300m and a r270 European produced unit. Can anyone give me any pointers on what to do. I did pull the cluster and open back to find a angled NEC chip 0719k I believe I do see one small soic eeprom chip with unfamiliar numbers on it. Not sure what I’m reading about lcm modules ? Is there a Cas that needs to be done on these?
Find 35080 read through R270 which you have. There is no CAS there EWS.
If it’s a E46 you need to change LKM, EWS and IKE
If it’s a E90 you need to change CAS and IKE
You can do only dash (IKE). If you don’t do LKM there is a possibility old KM returns.
If you don’t do EWS your key’s will have old KM in it.
2004 has a 35080 eeprom in it.
Hope it helps!
