That's an 8 gallon shop vac...
Sunroof drain grommet was definitely clogged.
Could anything else be leaking in here that I should check while it's apart?

Wow, Let that air out for a while! The grommet you're talking about is the one in the A-pillar just above the dash? Make sure you check both sides, there's one in the driver's side too.
If yours are the older kind that close up like a star shape on the bottom, trim that material off so there is no obstruction.
Before you button all the interior back up, run a garden hose on the sun roof for a while to check for additional leaks.

You have lots of company- http://forums.swedespeed.com/showthread.php?102526-How-To-Sunroof-drain-repair as a start. But there are lots and lost of posts on this across the model line (XC90 more so, at least as I've ever seen).
Check grommet and elbow, but before that open the sunroof and make sure it's not got debris at the front drain area that would inevitably go back down once everything was put back together.
Bummer to hear this, was one of the first things I checked when I bought my "other" XC90 a little more than a year ago.
For anyone reading, now is a very good time to check to see if your drain path is open, the bottom grommet is clear of debris, and the elbow is connected to the hose.

Good call! I happened to check the drivers side "just in case" and hose was completely disconnected from the grommet! Luckily (sort of), the drain hole in the sunroof tray was clogged on that side so all the water drained out the passenger side regardless.
Going to fix it all and retest.

How's the lining on the sunroof shade. Our 07 had stained badly from the previous owner. The foam backing had deteriated which was a red tar in colour and feel. when you touched it your finger impression was left perminantly. I removed the glass then the shade. Got a match on the fabric $22 for 1 linial meter. $10 for spray glue. Re trimmed it and it looks like new. I now have spare fabric should I need to do it again. Took about 2 hours. Wasn't about to pay $500 for a new one. I also noticed the sunroof rubber on ours had perished a little. There was also a gap on the back edge where the gasket buts back to itself. Water was getting into the roof from there excessivly. Super glued it back together and now not so much water enters the drain. Wife recons the car smells like a new one. Sorry no pictures. Haven't worked out how to do that yet.

I'd make sure you get it nice and dry down there. Last thing you want is mouldy spores forming on the foam padding. It will smell stale and there is no amount of smelly trees that you can hang from the centre mirror that will get rid of it. [emoji268][emoji268][emoji268]
My wife has a realy acute sense of smell. Not only can she smell bull s#!t but she recons our car has a mouldy smell about it. I can't smell a thing over my leather care. Prob the reason the last owner sold it in her eyes.

Interesting twist on this problem. Have a 2005 XC90 5-seater with fabric interior which means no sunroof (unless ordered "special", which this car was not).
Since this is our second car, we park it outside (near a large pine tree) and a review of my signature will note that I live in the Pacific Northwest which received a butt-load of rain and wind over the last 5 days or so.
I got into the car today and smelled something like a mix of yogurt and old feet. Asked around, hoping it was something simple like a family member moving an aquarium or something like. Nope.
Passenger side top mat was wet, under cushion wet. Not sloshing but very wet. Pulled the front seat and removed the carpet and discovered how well the floor foam soaks up fluids.
Did some poking around the fan drain (upper right passenger foot-well). Nice and tight.
Only other logical path for water ingress is under the front cowl below the windshield, both sides have a plenum so checked the passenger side.
A clogged cowl drain on the passenger side forced active rain to rise inside the cowl to the point where it rode over the passenger side plenum lip. A good look will note that the driver's side (over the CEM) has a plenum cover which is bolted on. Sometimes the driver side leaks as well (separate post about that, TNN for repair with 2004-2005 XC90s) but since the issue was on the passenger side only, it had to be the plenum cover right over the fan, water overrode the small fan drain and got in, probably through the fan assembly.
Have photos that I hope will be visibile- https://goo.gl/photos/71CVt9dUV8NjrbZu6 . In some you can see that the plenum cover seal is pretty old and dried out. It's also clipped in instead of being bolted down so has some wiggle (and likely open space). Cleaned everything up and ran a bead of silicone on the seal as well as outside the plenum assembly. Carpet is drying, ought to be able to put everything back tomorrow
Moral of the story, water ingress is not caused solely by issues with the sunroof drain. And, if you park your car outside where there are pine trees, check for clogged cowl drains from time to time.

WELL... I'm back here again
This has been my lucky year. After fixing my sunroof drain, you recommended we all check the clogged cowl drain. I said I would, totally slipped back on priority list until I noticed more water in passenger footwell. Mat and carpet all dry and clean now... but I wish I heeded your advice.
I dont unferstand why not 1 car producer place my simple idea like many windows for home producer use we have allready rain sensor and connected to close automatically window on roof if start raining and no one is in car to close it. also for cabriolet is nice idea for close roof if start raining and you convertible is open. other side of water can enter on cable harness cover under windshield on all models up to 2008 when volvo modified cover metal bended a few cm up. all cem problems was related to water destroying cem. i changed after 1.5 year on new car imagine than other people who have water cem problems. volvo need to fix this for free as its design mistake not user.
Roof drain have 90° angle elbow. remove it connect new tube and place it as long you need out of car. there is lot of space to do this job as again will be clogged soon.

Another update, was under my '05 yesterday working on a mysterious front end "clunk" when turning on an incline, and stuck my hand up the driver side cowl drain from underneath. Pulled about 1 cup of packed pine needles and vegetable "junk" out of the drain itself. Top looked pretty good (see photos in subpost #10) so this was all inside the drain tube (held in by the flapper valve at bottom). A review will note that I park this vehicle by a pine tree and it's maybe 8 years worth of junk (never cleaned before) but the interesting part is that I could see no obstruction from the top of the drain, under the cowl screen. Cleaned both drain tubes (passenger side was already pretty clean) then ran hot water through them both.
Figured to add this comment as I was very surprised as to how much junk was in the driver side, this is was for sure a contributor to the amount of total water I had under the cowl when my passenger side flooded.

Nice find! It seems like when you think you check everything, there is ONE more location water can leak from
NON-VOLVO content but case in point: My wife's convertible had a soaked passenger side floor a few weeks back. (I guess it's my lucky year!!)
Checked the usual suspects discussed at length on the Audi forums...Cowl drains, clogged AC evap drain, windshield seal, door seals...
![Image]()
Any guesses as to where it was coming from?

Rear windshield to top canvas adhesive deteriorated. D'oh! Should've thought to look here first.

Sorry- gotta take a step back for a sec (and good catch on the Audi)-
Interesting issue, the plenum cover thing. Was made aware of the driver side many years ago and have been watching off and on but, based on the amount of crap that came from the drain yesterday, perhaps not well enough. Lucky me in a way that, when my problem came up, only the passenger side was affected. I now realize it could have been far worse.
So why's this guy going on about cowl and plenum covers? If you're not a 2005-2006 XC90, you don't need to read this post, but instead you can refer to the earlier post about the passenger side drain, that's consistent across the model years after years of heat makes the seal under the plenum cover opening a little more rigid. That side at least has a lip so it's harder to flood (mine did under a specific set of circumstances as noted earlier)
But- for the model year subset (of which my '05 is included), there is a potential for water ingress from the driver's side which, if it occurs, can lead to a failed CEM (=dead or way wacky car), and maybe a hosed up wire loom. This in addition to flooding damage and/ or a new yaw sensor.
The issue is specific to MY2005-2005, structure (build) week 200425-200539 (9/20/04 to 11/2/05), chassis (last 6 of VIN) 134000 to 256551 (revised per Volvo docs in the NHTS link). Without going through the entirety (the link has more documents than could choke a small horse), if not repaired with a revised plenum (or, as you'll soon learn- time and silicone), these cars can have a potential flooding issue not related to sunroof drains.
Can see link for reference: http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/ACM16554038/INRD-PE10025-44260P.PDF (if you go up one level, can view the whole set).
And not directly related but for future use, Vehicle Type code (noted in many TNNs and recalls) is listed here: https://www.volvotechinfo.com/index.cfm?event=viewFile&fileName=TJ19245-2015-04-02.pdf, XC90 is 275.
No reason to cause alarm, just another thing to consider when considering buying an older used XC90. You'll want to check the drains regardless by the way, or so I have now re-realized. Next time you're under the car, locate them and make sure they're properly fitted and working.
As a point of reference, my '05 is chassis 135488 so I'm in the range.

I have not personally replaced mine but it's easy enough to do, whole floor padding and carpet pops out (had mine resting above a forced air heat register for a day to dry when I had my water ingress). New, each side is $280 before shipping, this being the "discount" price. Used ought to be much cheaper.
If anyone is interested in what the revised plenum cover and sleeve looks like, see https://goo.gl/photos/esYt29Yxxh5acEvE7 for some visuals.
Will do the swap when the weather warms up, just to omit another potential cause for in-car leaks on my '05.
Again, not necessarily required by default but easy enough to do the re-work for my own peace of mind.
Tie-wraps for both ends of the sleeve are required, I have them (good quality, high temp) at home so did not order.
Will try and get some before/after photos when I get around to this.

This prompted me to check mine yesterday. I'm glad I did. Left side was fine, though the tube felt a little loose. I snipped the fitting, added some epoxy, and put it back together. Right side - well... tube disconnected, but a good 2" of it was smashed nearly shut. I'm guessing it's been like that since the factory, or someone was in there before. I snipped the fitting, attempted to restore the hose, and put it back together with some epoxy. I'll have to get some new hose to fix it right. If I get some time today, I'm going to pull the amp and check for water. If there is some there, I can't imagine it's much. I don't hear any sloshing around, which is a good thing.
Wow this reiterates my thinking!
Always keep all drains clear of organic muck.
As part of my car cleaning I always check under the hood and remove all leaves and much from in front of the windscreen
Flush the sunroof drains with hot soapy water once a year, and keep the sunroof area clean of dirt.
I also polished the sunroof paintwork with car polish to help stop dirt sticking
Use a garage and undercover parking as much as possible. Try always to avoid parking under trees especially on windy days.
Keep car parked level as much as possible to allow sunroof to drain through all 4 drains and not overload any single drain.
Whenever you have anything apart on your car, clean the dirt off and apply polish/wax to any painted areas to help preserve them
Sounds obsessive and compulsive, but helps with long term life of the car!
