Bought our 07 Sport on Saturday and just figured out the AWD is not working, just like my 07 R was. Seems like the exact same thing, the pressure sensor switch, but I'll let them figure that out. I know the service department probably cringed when they saw me buying another Volvo. I have piss-poor luck I guess.

I had the same issue with mine. Apparently the failure rate has gone WAY down so our new pressure switches should last. <Keeping fingers crossed.>

Re: Well, It Took All of 4 Days! (S80-T6_Toronto)

Yes, please tell us how. <p>Maybe there's a bigger reason for the huge difference in winter traction between our Sequoia and the XC-90 besides studded tires and more mass.<p>When we bought the XC-90 in November, we decided to hold off on buying dedicated winter tires until next fall. That was before we knew that this winter was going to be so cold and so long. Stinking global warming! <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> <p>

Knowing how my R felt when that switch went bad, I knew that those tires should NEVER slip on a pre-charged Haldex system. <p>Pretty simple, get your tires wet and floor it, if they slip, you're screwed, like me.

If the tires are wet and they slip any at all, unless your tires are bald, your AWD isn't working. I let it go on my R for a while because I thought it was normal to have a little slipping, but on the pre-charged Haldex, there should be ZERO slip and after they fixed my pressure sensor on my R, it absolutely won't slip on pavement, wet or dry.

Re: Well, It Took All of 4 Days! (Husker Z)

I get some slippage on my XC90 Sport in wet or snowy conditions even with snow tires. I had it checked out when I first heard about the pressure sensor issue but the shop said everything was normal. <p>I had virtually no slippage on my R but had concluded that it was atributable to the different characteristics of the two vehicles. Have you been told definitively that there will be virtually no slippage on the XC90 if the system is functioning properly or are you just extrapolating from your experience with the R?<p> I may be heading back to the shop.

But, I do know that it was spinning way more than it should have in that snow and with just damp tires, it shouldn't spin. Not with the precharged Haldex, not unless I was getting all over it, which I wasn't, I was just pulling out into traffic. <p>I'll know more this Friday.

Also, they replaced the right rear wheel bearing and will be replacing both drive axles as well due to a vibration when accelerating. <p>I think if you have 30K on your AWD and you haven't had your pressure switch replaced, you need to.

Thanks Husker Z. I actually tried it out today. There was some sand on the onramp (flat surface) and I accelerated quickly, and what should I hear, but squealing tires. I also did not notice any traction triangle coming on. <p>It felt more like it was one of the rear tires slipping- is this still a sign of a failure in the AWD?

Are you sure it should be "zero" spin?<p>My front tires regularly chirp on acceleration, yet when we had snow and ice this year, I floored it to check it out and the rear tires did spin.
