Hi,
It aint gonna work that way!
you have to find a virgin read, and do it with bdm..............

no other way , unless you have a matched set of ews3,key, and ecu..for it to start!

hope this helps.....

Have you tried using INPA to read the ISN from the DME? ...and then used INPA again to write the ISN to the EWS module?
