    Coding a new EWS 4 on 325i

    This is off topic. Sorry. Hoping someone here knows the answer.

    Friend of mine has an E46 325i (MS42 i believe). The connector on his EWS fell apart. He ordered a new EWS from the dealer with his VIN and they gave him an EWS IV (his original was 3).

    We tried syncing the new EWS to the DME using both INPA and ISTA and it did not work. Get some form of communication failure in each tool.

    Any ideas?
