Intermittent AWD in 06 XC90
Hi All:
I'm having some trouble with the AWD on my wife's 2006 XC90 2.5T. In brief, the AWD only works intermittently. And with a quarter mile unpaved driveway that at points its 50 degrees in incline--in Vermont--this is a problem.
After ruling out the angle gear (driveshaft still spinning, no grinding noises), attention was turned to the Haldex. Since the computer had codes stored indicating problems with the pump, I had the pump, filter, and fluid replaced.
Naturally, however, this seemingly did nothing--aside from eliminate the DEM codes. So now I'm left with intermittent AWD and no indication from the computer what the problem could be.
I should note that I have also tried cleaning the contacts on the wiring harness that contacts to the DEM. I have also checked the REM, and it is working fine.
Any insight would be appreciated.
Thanks in advance.
Oliver
