I have the same exact problem. I have E39 (1999,528i, automatic) which
i bought 4 months ago from a BMW-reseller. It worked fine during the first
3 months but now I have the same problem as you do!
The car has been repaired at least 4 times and it works ok for a couple
of days and then it won't start!
They told me that they ordered a new EWS from Germany (I live in Finland)
ja reprogrammed it -> didn't help. Then they updated a newer software
for it -> didn't help.
Are you still having the same problem or do you know any remedy for it?
My car is currently at authorized BMW-seller but they are baffled about
the problem. I found this at the internet:
Intermittent crank/No start
E36-328i (M52), M3 (S52), and E39-528i (M52)
The engine will crank intermittently but will not start.
The DME should be reprogrammed using MODIC P9.0 or higher.
Once reprogrammed clear all faults

They then said my EWS was at fault and I would have to go to the dealership, I got a new one it programed by BMW of Bellevue. Car worked fine after this but...a few days later.... same problem, starter was turning over but no start. Had BMW of Bellevue look at again, they said that the information that was loaded was loading incorrectly. After paying for another tow they programmed it again.I got my car back and whoops 4 days later... same problem. I took it back to BMW of Bellevue, and they now said that my DME was at fault. I had a new DME put in and re-programed again. Got my car back and again 4-5 days later here I am. Same problem minus $2000 bucks from my pocket! I don't feel 100% comfortable with the dealership and feel ripped off about now, does anyone know what this issue could be? Please help!
