Moving on and chalked up as a lesson learned...BMWNA sided with the dealer-denied!!
They said it was up to the dealer as to whether further consideration is warranted- funny, that's what the dealer said about BMWNA.
Granted, this appears to be my fault according to the diagnostic results but it makes me a bit leary about BMW warranty coverage in general. For all I know, I have an undiagnosed drain down problem still lurking.....Time will tell
Thanks for all the feedback folks
