3). I can actually do a burn-out from standing....it's an all-wheel drive to boot

Uhm, your all wheel drive is broken then.
Even on very wet pavement you should NOT have anything like a burnout, even if this was a modded V70R with 400HP. Just a tiny chirp from the front tires (maybe) and then nothing but grip is what should happen if your AWD actually worked, especially since you have an 07 with the newer generation Haldex.

(You need 700HP+ like you get from an Aventador or Veyron to get an AWD burnout when your car weighs 2 tons. Evos and STIs that are lighter can maybe do a brief AWD burnout with 500-600 HP).

Sorry to rain on your parade... maybe take the refund and put that towards your AWD repair if you're short on savings?

 

Man what a downer,good thing is.. you're wrong about needing a 700+hp to get a AWD burnout.

Not my video, but I owned the identical car (B5 S4 stg 3+) ~380 awhp and a "burnout" was easy and at 3900 lbs (~ 2 tons) with me in it.

OP, Congrats and dont let these guys here rain on YOUR parade.

 

No rain...maybe a bit spitting.

I called Volvo service and explained what I was experiencing and they confidently walked me thru what should happen with the Polestar chip (since I was getting up snowy hills with ease this past winter ruling out that my AWD was defective). They said the initial acceleration will cause a wheel spin then quickly grab afterwards (I may have sounded like I was spinning out...I was overstating a tad).
This is typical and my car as they said is in immacculate condition . In my gut I felt good; and just to rule out any suspicions I'm due for an oil change and will have it looked at. When I read your reply no red lights went off.... just touched that someone would reply...thanks.

Not quite correct
It may give a VERY LITTLE tweak to the front wheels before the AWD grabs but you have an 07 with instant traction
I've done several brake torque starts with essentially no wheel spin
What tires are you running and how old are they, this means a LOT!
If they're old, a snow tires or a poor or old all season you may experience A LITTLE wheel spin.

The deal is this, if you have no AWD and you have a (power) tune, the wheel spin can be a lot and will keep on going for maybe 100 feet but if your AWD is working properly, even with poor tires, after the initial spin/torque steer the rear wheels should grab and the spinning stop and the car should be going straight, so which is it?

 

Good to hear the Polestar tune is worth it. :thumbup:

I can turn the DSTC off on one of my family member's 07 2.5T. It's been a while, but I think holding (for longer than you think) "Reset" on the blinker stalk while the display reads "DSTC on" will switch it off.

 

What it is, IS....

The tires are brand new, just installed this past spring (Michelins Energy MXV4 S8). I use the Swedish snow tires Gislavad Nordic) from the dealership.
I'm not spinning for 100ft...(at all!). So yes it is the latter.
You kinda seem bent on proving the AWD has failed....rest assured it ain't.
Thanks for your concerted interest though, I'm learning lots.

 

We're just trying to make sure you can verify AWD function correctly.
Try JRLs test on with jackstands, or if that isn't possible, turn of DSTC as esmith mentioned using the stalk and then do a brake stand launch. (Floor the brake, then gas, then release brake). You should get basically zero wheelspin, just a tiny chirp at most.

I wouldn't be surprised if your "tiny burnout" is actually the DSTC reining in power and "hiding" a broken AWD system. The above test will make it clear whether that is or is not the case.

 

I attempt that tomorrow...thank you Mr. Smith.

I could never go back and un-Polestar the V70, I having too much fun!

 

For your own edification, if you have a way to put it on jackstands, do so. Have someone sit in the car, turn it on and put it in gear (at idle)
If all the wheels are spinning then you at least know no hardware is broken (angle gear/collar sleeve).
After that if there are no stored VIDA codes, (DEM, AOC or pressure sensor) you should be OK.

 

Just completed the Drive Clean Emissions Test for my (licence plate) sticker renewal. I asked if they could hoist the car and check if the AWD is functioning. The guy asked why, I explained, he shrugged and replied, "you'd know if you lost the AWD by how your car was steering, it would be very noticable," and proceeded to put it on the jacks. They did it, and all four wheels moved (The front wheel started first). The mechanic said it all checked out...nothing broken.

I'm sure we all know the feeling when something's "just not right" and when the question was raised about the probability of the AWD being broken I didn't feel it in my gut.
I'm glad you guys made me aware of the possibility of this occurring though...thank you.

Oh, it passed the Emissions Test.

 

I asked if they could hoist the car and check if the AWD is functioning. The guy asked why, I explained, he shrugged and replied, "you'd know if you lost the AWD by how your car was steering, it would be very noticable," and proceeded to put it on the jacks.

The guy is not used to Volvos. AWD usually fails silently on these cars, and unless you floor it you might never notice unless you're trying to drive through deep snow.

 

Thanks Peter,

That's pretty impressive considering it's AWD. I'm not as knowledgeable about these matters as the experts, but it's nice to know someone's looking for the positive, or even better, being neutral. Sometimes what we get is determined by what we expect.

Nice car(s) Peter.

Best,

I don't want to bust your bubble but all the wheels on an 07 should start to turn as one.
If there was a delay something still could not be right.
You failed to mention how long the "delay" was, a split second or longer, 1-3 seconds?

 

Did I mention it also has Geartronic?...so in the auto-trans mode I typically cannot "burnout" but in the Manual, oui. The delay on the hoist was maybe a second, then the stabilizer control kicked in and wheels weren't able to turn no mo.

 

Eh?????

 

The last two words were no more. While the car was hoisted the other 3 wheels kicked in a half beat later. What more can I tell ya?
My AWD ain't broke.

 

Eldridge, no one is trying to rain on your parade, it's just that you had posted something that can mean there's a potential problem. My AWD, not being the year with "instatraction" will only chirp the tires a bit before the AWD system kicks in. On stands all the tires rotate simultaneously and react to speed inputs rapidly as monitored through the individual wheel speed sensors.

 

Just came back from the grocery store and noticed the DSTC has been off the whole time (even before the Polestar was installed)!!! This might answer why the wheels are spinning.
Apologies guys....I completely dropped the ball on that one. If the DSTC was on there would probably be little or no wheel spin? (I'm guessing here).

 

Again, even with Polestar, you shouldn't get anything more than a tiny "chirp" (split second) when you do a brake stand launch, if any spin at all.

Based on what happened on the lift (delayed AWD engagement - "While the car was hoisted the other 3 wheels kicked in a half beat later.") I would say your DEM/AOC pump may be starting to fail. I've seen Volvos have intermittent AWD issues if the AWD pump pressure isn't as high as it should be because the pump is starting to fail.

Suggest you go to a Volvo dealer or mechanic who can properly scan for codes using VIDA. You probably have at least one DEM code thrown. That said your test did at least confirm that your angle gear and collar are fine - that's good because those are a lot more expensive to fix.

 

How did you find the polestar tune on sale? I can't trust my local dealer and would kill for a polestar tune that's on sale.

 

I asked our local dealer on Friday about Polestar tune and they said it is not available. I kinda figured as much an 07 7+ years old. I would entertain having it done on my XC.
Wonder if I need to call around.
Best,

 

Of course it is, your dealer is an a-hole, completely unaware of his product
You can get a Polestar tune back to 2006s For some reason (but not in 2005s which are essentially the same).
I have one in my 06 now and had one in my 07 last year

 

Agree with JRL completely



After reading of his "Polestared" White 07XC in the Classifieds, I checked availability on the Polestar site, then visited my local dealer to inquire. At first I was told it wasn't available for my 07V70 2.5T but with a little "calm" insistence (and knowing of JRL's experience) that they check again. Indeed they agreed it could be done and two days later it was, for a reasonable price(with "kit" and labor & VCOA discount). Like the gentleman who started this thread I was impressed with the results and made an appointment for my wife's 07 XC and am very happy with the outcome of both vehicles (hers was about $100 cheaper same part#31342465-7 - something about had them in stock for a while and there was a new part # = more $?). Thanks again to JRL for the updates..:thumbup:

(not touching the wheel spin deal, If I'm into wheel spinning I use my Ol"Ford)

 

Just a follow up and to highlight, the 4-wheels-spinning test is not a guarantee the AWD is really fully working. Ours (my sons really) V70R 6MT passed that test on the lift but when the angle gear was pulled apart for a reseal, the collar and matching angle gear splines where thoroughly chewed up. Metal filings in between the teeth and in the grease, lots of rust. I suspect there was just enough friction to get the rears turning on the lift with no road resistance. On the road, I suspect it was effectively running as FWD.
We put in a used collar and angle gear from Erie Vovo. $1100 + labor vs $1800 +labor for new. Fingers crossed.
It's a tolerable design for 200 hp and an automatic (like an XC) but a really marginal design for the power and shock loading of an R with a stick.
Best of luck to the OP - hope he doesn't have to go thru what we did.

 

Why in the world would you install a USED collar gear, :facepalm: it's only about 140 bucks retail with seals, (I pay $110)

 

Hey Eldridge,

Thanks for the information. I also have a 2007 V70 2.5T AWD and always go back and forth with "chipping" it. I see the sale every year about this time. This is the first time I have seen someone post information about it on my car. So I assume you are still happy - if you then I think I will also pull the trigger. On a side note - have you lowered your car? I have seen mixed information on this and never quite sure what to believe.

Thanks

Volvo of Toronto had a sale for about a month and a half during the summer. The sales guy was quite friendly and offered to have it installed and refunded if I wasn't satisfied within 2 wks.
I'm quite pleased 3 months in.

 

I haven't lowered it...thought about it though.
