The "other" Awd Failure - Dem Stuff

Thanks a bunch! I am starting my investigation of my non-functioning AWD. I don't want to hijack the thread, but curious to know if NJGreenBud (or others) can offer

advice on the following codes that were pulled a few weeks back.

- BCM-0094 (note - in the details, it says pump engine, status "not active". Does this mean the haldex pump is kaput?). I don't understand what this frozen value field means.

-BCM-0100, 0115

- ECM-510F, 928C, 9400

Note -there were DDM, PDM's as well, but this is related to windows and mirrors (that much I figured out).

From the BCM and ECM's, it seems that the starting points should be:

-check DEM sensor / connector

-AOC (connector, grounds, check the oil, clean up the sensor....maybe replace it with the oil while we have it opened?)

-check CAN cable

Thanks! This advice helped a little bit, but the connectors were incredibly brittle, and suffered some damage (see pics attached). I tested to see if they still "connect" and they do.

Perhaps a bit of electrical tape or a hose clamp?

The unit wasn't super "dirty" on the backside, but from my chats with Xemodex (amazing tech help) the codes seemed to relate to a bad DEM. Now that winter's here, I need AWD again (especially on the Canadian prairies).

DEM back from Xemodex (within 1 day). The Xemodex tech mentioned "be careful' with the washer. I was told "it can only really only go on one way", but I am still perplexed. I did read the VADIS instructions regarding the washer "convex side against the temp / pressure sensor." I assume this is when you take the sensor out (something I didn't do).

Anyone want to chime in, which way do I put the washer in prior to the DEM going back on? I will repay in one virtual cold canadian barley beverage!
