I've been looking, but I haven't found that thread yet. I have learned a lot! I had no idea how common the EWS sync issue is. Note to self: never let the battery run down or leave the key in the ignition. If anyone wants an overview of EWS there's a pretty good one here:

(We use version 3.3)

It was a busy weekend (but I have tomorrow!). I inspected and cleaned the contacts on my OBD II port but that didn't make any difference. I did finally realize that I could find the manufacture date of my EWS ECU with the diagnostic function on the Foxwell. My EWS was built year '05, CW16 (which I am guessing means Calendar Week). That would put the build in April of '05 which makes sense since my car was built in May. That means I am pretty sure that inputting a March '05 build date (next option is September) should be right. I had been trying all sorts of permutations so it's nice to confirm that.

I may try to see if I can get BMW scanner going or maybe a proper update of the Foxwell (the last attempt failed).
