Well today was odd, my car sat for the last week or so and when I got around to driving her today there was no AWD. Before there was no issue and the only reason I noticed it was because I was on a very dirty asphalt road.

But now here is the crazy part, Now 2 hours after my last drive I have AWD. I was thinking I was crazy so made sure by rolling in 2nd on the same road and goosing the gas to see if I has wheel spin and there was none.

So I had zero Warnings on the display and I had no AWD all day till this last trip. I just had the DEM(?) replaced.

Re: No AWD? (MacFreak21)

Hmm... It possibly could be a loose connection or something in relation to the pressure sensor (AOC) Active On demand Coupling is the part that seems to be causing you the issue... It seems strange that it fixed itself after a shutdown, making me believe it to be sensor or electrical based as opposed to mechanical. Even though you stated you had no messages make sure the computers did not through a soft code... (Pretty much marks an event but does not diplay a message or warning light... I would definately go into the dealer and at least politely demand a visual inspection and a review of the cars logging database. http://********************/smile/emthup.gif

yep, i am waiting for the service manger to get in from vacation. Then we can setup a tow and loaner since I am 400 miles away and rentals are very expensive when the R is down. Maybe they can install the reverse sensor that borton forgot to install.

JRL posted a while back that the original source of this DEM consternation was not the actual DEM itself, but the connection.

I believe he said that you need to remove the boot / connection and clean it out.

I bet since you just had your DEM replaced that there is likely contamination in the connection since it's fluky.

BTW, no info on the dash is normal.

I am going to check tonight the connection. It did it again today, I just had to run out to get some photos and I had mad torque steer and when I restarted the car after sitting for about 10 min I had AWD again. Oh well.
