Fuse 47 is good.

ok... lets check starter relay - in the engine compartment, on the passenger side, closer to the hood hinge... here is the picture of it, relay K6324.

next one may call for more digging inthe glove compartment, actually, behind it, where more fuses are... that would be fuse 105... careful around that fuse, a LOT of juice passing there!!!

I appreciate your help terminator, but I am going to call it a day and try those things you suggested tomorrow. It is getting cold and I have had enough frustration for one day, lol. If you are around tomorrow, I would love more help!

cool..

actually in the morning, you might be able to just fire it up.... who knows... lol...

good night...

It sure would be nice if it would start up. By the way, this car has the auto start feature, if that makes any difference?

most of them do - it does not matter at this stage of troubleshooting... we are not deep enough into oil and grease... lol...:p:

I hate to throw cold water on the situation...but with everything you've tried and still get no start...and if I understand correctly...when you turn the ignition to the start position...you hear & get absolutely nothing (no clicking from the starter, or "urr, urr, urr" from the engine's attempt to turn over)...I think the issue may be with the EWS system.

I've seen this happen before on either an e38 or e39 forum...where the key was left in the ignition (just like your situation)...and the battery was drained. The issue turned out to be that EWS got out of sync. With the key being in the ignition and turned to position 1 where some control modules are initiated...then the battery draining and losing power...yet the key is still in the ignition where communication with the transponder could have been initiated as the car's battery voltage begin to drop...EWS could have gotten out of sync.

It takes BMW DIS to resync EWS...it is not like the FZV/DWA features of the key that can be reinitialized in your driveway.

BTW...the dealership gave you some incorrect info...the battery inside the key has no affect on it's ability to START the car. The battery is only required for FZV & DWA (remote locking/unlocking of the central locking system & arming/disarming of the anti-theft alarm siren system).

I have seen keys sporadically not send the pass key, your key could be bad. Try another key if you have it. I have also seen loss of EWS calibration.

Carsoft 6.5 can resync the key with the EWS.

fuse 105 feeds into the EWS system. and the EWS feeds into the starter...

i am running out of ideas here, so, some fresh blood is needed.. lol...
