No Codes. They say they are hunting for a loose wire. Any one care to chime in on this on?

DEM (Differential Electronic Module) - temperature sensor. Will cause your Haldex to fail possibly without codes. <p>Tell them to look for the TNN with this. <p><A HREF="http://forums.swedespeed.com/zerothread?id=90369" TARGET="_blank">http://forums.swedespeed.com/zerothread?id=90369</A>

I went in with a punch list of a dozen action items, most with TNN's. The Service advisor told me they do not use them anymore... I chuckled to myself... Later in the car with the mechanic, he mentioned TNN's. Thanks for the info, I will send it to them on Monday.

Occurs to me, that they replaced the DEM back in March.... They mentioned that today.<p>Just looked up the records. I went in with the Antiskid light on... Took 3 visits. <br>1)Replaced demand Coupling/Replaced DEM Temp Sensor March 10th<br>2)Replaced DEM, Control Unit, etc... That was March 17th . 3000 miles ago.

It only connects to the car with a 4 wire harness. 2 of those wire are for the canbus. Pretty easy to eliminate wiring as a problem.<p>The harness goes under the back seat, drivers side.
