2010 S80 T6 water in passenger side - not sure it’s sunroof Topic is solved

That's exactly how I found my leak. I poured water into the sunroof drain and accidentally got water on the windshield. With the A-Pillar cover off and head liner pryed open a bit I saw water rolling along the glass edge towards A-Pillar from the windshield seam!

However I did not have water behind the glovebox. I was able to observed water drain out below car when I poured water directly into the sunroof drain. It drained between door and fender well under vehicle.

Good luck. BTW I bit the bullet and had a new windshield put in professionally for around $400. Ouch.

Luckily this is my secondary car so I am putting off to the weekend. Glass place told me a reseal is $220 but if it breaks when they pull off the windshield it’s new glass time.

Just confirmed it 100% the top of the windshield leaking and allowing water to enter.

Have to check out of the glass shop can reseal it or if I need a new windshield.

Windshield had to be replaced. For anyone with water issues on the P3 chassis the windshield should be the first thing checked.
From the inside of the car push outward and see if it lifts. If you see movement then water/moisture is getting in. Or take a bucket of water and pour along the top seam of the windshield and see if water makes it through. Can use soapy water with air hose from inside to check for bubbles as well.

Glass repair shop stated 50/50 if windshield will break while removing to reseal it. Budget accordingly. Cost me $447 at Portland Glass in New Hampshire.

Honestly disappointed in Volvo for not covering what is clearly a manufacturing defect.
