BMW X3 E83 EWS
Hello

Should change on a X3 E83 the EWS unit.  From time to time car does not start.
(61 35 9 145 097  EWS IV EWS 4.3)


Is it enough to flash the old EWS dump to the new EWS and sync ews and DDE.

Have AK90 for reading EWS

RE: BMW X3 E83 EWS
Think my car has EWS3 (its a 2006),
don't remove it until now. . When I ordered new one, I got a EWS4?? How can I adapt the EWS4.
Have AK90, Autel IM508, but only with Xp200, Inpa, NCS expert,...

RE: BMW X3 E83 EWS
did you order brand new from bmw dealership based on your VIN?

you must remove the original and find out which version ews module you have in order to purchase the correct part if you want to be successful in cloning the module.

If you ordered from the dealer based on VIN then all keys should be included.
You need only sync EWS - DME/DDE

Read on other forum when you upgrade from EWS3 to EWS4, DDE should update to latest software, otherwere car stops after few weeks. Is this true?

I think I forgot, the new EWS must be coded to the car!

If you code it, then you also set it to EWS3, in vain it is one EWS4.
