Yeah, claim they they have no idea(basically)... We are at replacing the entire transfer case, which makes no sense to me because there are no drivability problems other than this stupid code coming up. Not a noise, a shudder, a bang, no slipping, nothing.

Any updates on this? Mines completely falling on it's face to the point where it's becoming undriveable...highway speeds is OK but backroads and it'll force itself into Neutral or Park as I'm doing slow turns and whatnot.

I recently reviewed the codes after having trouble with ISTA reading in German and the NT510 not showing at what mileage the codes occurred and then a nasty breakup sidelined things for a few months. The codes that I pulled did not show anything until the point that I disconnected the transfer case. So, that really didn't give me anything to go on.

I might just replace the wheel speed sensor on both of the front wheels. Other things I have done is replace the front driveshaft (unrelated), replace the transfer case motor gear, replace the transfer case fluid, differential fluids, and transmission fluid. I haven't started the car yet, as I'm waiting for my DDE to return from tuning, and then I will reconnect the transfer case module, and can start fresh with potential codes. Of course I'll be holding on to the steering wheel tightly to avoid getting pulled into a ditch.

Sorry that doesn't really help m5james, but it seems like your symptoms might be different anyway. What do your codes say?

James, it makes sense in your case to consider replacing the Transfer Case. Also, have you pulled the glove box? There’s a TSB that says there’s been issues with wires in the dash, behind the glove box on e70s made before 2011 that wires were being cut by the sharp metal dash and the “fix is to wrap in felt tape”. Think we discussed this over text.. Mine was wrapped in tape, but when I removed the tape I found two or three wires had been chaffed, and a wire at the suspension control module(accessible on the side of the dash) wasn’t plugged in all the way.


Note the sharp metal of the dash



This was my favorite. The blower motor wire hanging by a thread... No wonder BMWs have burned down because of this harness/plug...

Note the sharp metal...

The fix, automotive carpet, spray glued to metal and around the wiring.

I mention this TSB because it talks about my code 5DEA and lists many other totally random codes, including can bus, transfer case and many other codes....

Ummm... yeah I'm going to have to look into that as a precautionary measure.

Can you post the tsb or a link to it? Not sure if my build date of 09/10 is affected...

I can’t find the correct one anymore. But it was ALL e70s up to 2011. So, anything built in 2010 and earlier... That would most definitely include yours robnitro

This is NOT the one I originally found, but it’s all I can find now... Pretty close

Mine is a MY 2011, but I believe was manufactured in 2010 as well. I would like to look at the wiring behind the glovebox.

Was the glovebox difficult to remove? And is there a DIY on it?
