Yes to the push pin question.

I assume you are talking about the bumper where it attaches along the top to the frame above the rad?

Is it necessary to remove the bumper?

I have a 2007 XC70, I believe this means:

Haldex III,
always 4WD up to 40KM,
over 40km "pre-loaded" (what ever that means?) so rear wheels engage "instantly" when the fronts slip?
...

How does one determine if the Haldex is working?

I did one of my regular town 200km round trip today in falling 2-3” mix of snow and drizzle weather.

To gather more data points, experience and contrast I left DSTC On, last 80km home....

Were both an VY70XC and the XC70 models sold in the same years? (I believe yes.)

Is a 2000 Volvo V70XC AWD SE is the same as a 2000 XC70? Differences?

I know and accept that each of us renders opinions based on their own experiences.

As I wonder about folks like you who do not read yet choose to make negative comments.

See post #5 and #8 above re my response about snow tires - 4 almost new on the car.

As to your comment...

It seems to me that the various comments in this (and other) threads make clear that the myth of "Volvo's natural element being snow" is exactly that - a myth.

My previous vehicles were a 1983...

Update & Question:

Do I have this right?: my 07 xc70 is normally a 90%-10% front wheel drive bias; haldex is activated/de-activated based on slippage at front wheels and operates in milliseconds...

I did some searching and found a thread in which JRL says:

"Tracs doesn't do much in these cars but if you're stuck in the snow, you want ALL 4 wheels driving and not having something artificial...

Although I find your comment very confusing it seems we agree that the XC70 could be better than it actually is under adverse winter conditions regardless of equipment present in the various...

"According to the specs at VolvoUSA web site under Roadholding, the 2005 (and my 2004) have TRACS standard, with DSTC optional.

It ain't funny Bill, it's early winter.

Wet slush update:

We are above zero and have had rain overnight, roads are now 3-4" of slush over semi-frozen gravel, DSTC Off seems to work best if one is more comfortable feeling direct...

Will do. My read of Exocet's post is his DSTC On behaviour was/is the same as I experienced except that I can turn mine off via the stalk. I plan to replicate one of the experiences that...
