Is Your Rear Wheel Drive Not Engaging?
AWD Traction Failure on an XC70
wz-dc » Driving in our recent snow storms, with four new studded tires on: my XC-70 was noticeably lacking in traction. Sitting on a slippery slope with an observer watching, it is obvious that the rear wheels are NOT engaging, and that the front wheels spin wildly. Any body else experience this ? What is the fix?
Fam_mach » Please share what your dealer indicates as the problem. My XC70 is a dog on snow and ice conditions that are no problem for a Subaru… Your problem sounds similar to my experience and would like to know what your outcome is?
wz-dc » My vehicle was repaired at Rickenbaugh volvo in Denver.
It turns out that the temp/pressure sensor was defective. They replaced the sensor, and reloaded/updated the software. Voila!! I have AWD again… 
The good news: they did it for no charge even though I am out of warranty. 
The bad news: I whacked a deer on the way to the dealer @ 5 am, and sustained an estimated $6000. in damages ( I bought my current xc because my ’98 xc was totaled by a REALLY BIG deer).
Angle gear is the more common problem with P2 AWD Volvos. Look into that if you rear wheels aren’t getting power or traction.
Here is a handy Volvo AWD overview of the systems and mechanicals that make it work.

well friend what I did was uninstall the Bevel Gear opened it, and notice that the pinion was slippering on the shaft where the 2 bearings are mounted, after I welded to the shaft to leave it fixed.
then assemble everything install again and ready no more lack of traction.
