2001 E46 EWS Rolling code sync issue
Guys after a bit of technical help...
My mates 2001 330d e46 has got a EWS error after recent battery issues. Basically the EWS is not accepting the key comes up with Random Code Error. The error shows in the DDE fault log and the EWS fault log. Car does not crank...
What we have tried so far:
Re syncing the DDE with the EWS in INPA via DDE>EWS SYNC Values. We can get the codes to clear down after doing this but wont start and same EWS random key code comes back in.
In DIS under Service Functions > EWS > we have ran the various test plans, on the key status plan everything comes back as expected apart from the key random code, reports NOT OK. Tried the WRITE KEY Variant plan, this wont allow you to disable or enable the currently active keys.
Try to run the EWS III Calibration plan, this wont run, just comes up with various errors ??
I have SSS/Progman and this communicates with the car....anything in this we can try ...not done to much exploring in this due to not wanting mess up the VO.
Any subjections of what to try next? and yes he only has 1 key!
