Did the P2 S80 (1999-2006) have different seat options, such as sport seats?
From what I can read in the various posts, I believe the connectors underneath the seats changed after 2003, so 2004-2006 models might not be plug compatible with seats from earlier years.

I've got a 2004 2.5 AWD, black on black. The passenger seat moves correctly, but my wife doesn't think the seat heaters are doing anything. The driver's seat is intermittent in its movements. I've tried three different side switch assemblies, and the problem persists, so that makes me think the issue might be with the motors rather than the switches. I don't believe my seat heater is working either and I've swapped in two different heating modules.

So that leads me to think it's time to see if I can find some other driver's seat. Other posters have pointed out that S70, S60, V70 seats might not fit plug-wise, and would likely be slightly narrower (not a problem, as neither of us are very wide).

My S80 seat has a front gusseted pocket (where it's very handy to keep insurance and registration cards) if that helps to identify which one is in my car. Very comfortable seat, but without any ability to adjust position, less than ideal for multiple drivers.

Any P2 S80 seat swapping gurus out there?
 
Waiting for the answer to questions like this on here will give you grey hair lol.

Apparently no one with an enthusiast bone in their body is interested in anything other than the high-strung but apparently supremely unreliable, but cute R-Series. Good luck on finding your answer because as an enthusiast and Volvo lover that doesn't WANT an R series and am HAPPY AS Fu* with my S80...i took matters into my own hands and had a lot of trial and error figuring out things on my own.

Good luck on finding and answer when everything's focused on that other car....

Thanks K of P.
I agree with you that the P2 S80 is off the radar of almost every Volvo forum, but it never hurts to put the questions out there.

Did you ever need to swap the control unit under the seat? I've been focusing on the side controls as the cause of the intermittent issue, and forgetting that there's something between the controls and the motors.

And I already have grey hair (mostly). My view is that I don't care what color it is, as long as it's still on my head.

PM me if there's any P2 S80 help you need or advice you care to share.
 
Oddly, you're right. The s80 was marketed and sold as a more executive line. Not much in the way of enthusiast mod or anything for these as the people who could buy them were 50 or older then and are 60 or more now. You're in the minority for sure. I always liked the s80 but the lines weren't as sporty. When getting back into Volvos I was amazed at the affordability vs the s60 and v70. Post your question somewhere that has a lot more activity and it'll get traffic. I just happen to browse new posts vs specific areas in here because I'm curious about t5rs, v60s, all of em! Many of the people over in the more active threads are super knowledgeable about volvo in general (p2 platform overall) and I'm sure would be happy to help.
And yes- any color as long as it's there on your head is right!
 
If I'm not mistaken all but the Executive model of the S80 got the "Sport" seats in the 06MY. Also from what I've read year to year of the same platform fits the plugs with a few later years for the S/V60 and XC90. Found that out in another subsection of this forum.

As far as the marketing of the S80 it was an upscale vehicle marketed at the more affluent buyer but as is obvious with BMW and Audi buyers those ppl want to modify and have performance in their vehicles also. I guess with this line we've got to innovate and experience ourselves. Doesn't hurt...it's just expensive and time consuming lol. Surely wish this vehicle had a bigger following whereas the S60 is decent it's just too small and quirky for my personal tastes.

Yes, all 2006 S80's had Sport Seats, front and back.
 
I swapped in set of sport seats from an 06. Best upgrade I've done so far on the interior aside from the HU850 install. Your's being an 04 you'll have to find an 01-04 plug style, or I'm fairly sure you can swap the cushions onto the seat frame from a newer one but cannot comment any further. These s80s are definitely very under the radar of most who don't know. Since I got mine a year ago it has been my favorite daily driver to date. I plan on doing a few more mods to mine, going to do a hilton tune, likely throw a 16t or k24 on it, still contemplating putting an R engine in it later on :D I want it to be a comfortable, quick, daily driver and sleeper. I'd definitely ditch the 16" wheels that most came with. i put pegs on mine and love the look. Also can upgrade the front brakes to the 305mm rotors by just changing brackets. OH and all the p2 seats I've ever seen all have the front pocket.

I was re-reading the other thread from 91shelby, where he has detailed what he's done to his S80, and I realized that he posted a picture where the sport seats are in the car, and the older regular seat is outside the car. Based on the difference in the way the seams on the seat back run, I've just concluded that I ALREADY HAVE the sport seats. They were listed on the original window sticker as "Premium Leather" and not as sport seats. And yes, they are wonderfully comfortable seats.

But I can see that the bolsters are higher on my seats than the one that is in the picture outside the car, so that also indicates the sport seats are already installed!

So now I just need to fix the lack of movement (likely the control module under the seat) and see if I can dial up the heat from the seat heaters.
 
So 04-06 aren't compatible? That's odd since it was the facelift model. Seems they'd change the wiring to match generations...hmm

No, the 04's had the same connector as the 03 (and not sure how far back, to 01?). The 05-06 went to the new connector. Check these two pics in Shelby's thread http://forums.swedespeed.com/showth...ead.php?301945-My-05-2-5T-Daily-Driver-Project&p=3696113&viewfull=1#post3696113 ... I have the connector in the 1st pic (with the cover that pulls open to reveal the connectors), but he has a 2005 and his connectors look like the the 2nd pic. Plus there's an occupancy weight sensor on the passenger seat for the airbag on 05-06 and you'd have to work around that along with rewiring.

An update.
Now that I've discovered I've got sport seats, I set about trying to fix the seat non-movement issue. Found a 2005 S60 in my local LKQ, and yes the connectors are different, but they use the same control unit as my 2004 S80, so I pulled the control unit. Installed it, and voila, the seat moves. I bolt down the seat again and go to sit in the seat, and the seat moves then stops (huh?).

The next few minutes are me trying to figure out what is the issue. All the switches were working, and the seat was moving in all directions. I take about 10 minutes to try to figure out what I could be missing. Get back in the car, and now the seat moves again. I go for a drive and try to make a small adjustment, but no movement. It's two days since I did the control unit swap and it seems as though I can only move the seat when I first get in the car and before I drive. Now the seat is in a very comfortable position so I'm not in any distress, but I'm confused about how this seat is responding.

In reading the manual (hey, I'll admit when I need to read it), I see that the car has a feature where if the car is unlocked and ignition off, you can adjust the seat for up to 10 minutes if the door is open. If the car is ignition off and door closed, I have up to 40 seconds to make any adjustments.

Now the manual says I should be able to adjust the driver's seat if the key is in position I or II (which is normal drive position), but my car seems to be following the rules for adjustment with no key. I'm more curious than concerned, but does anyone know what is controlling this restriction on when I can adjust the seat?
 
Odd issue for sure. Do you have Vida/Dice? There might be a code there that could help track this down. I guess replacing motors could be the next step. I suppose it could possibly be a pinched cable going to the appropriate motor as well. I've never had to dig that deep to know which of the three motors controls the fore-to-motion but I'm sure you can figure it out. Are you taking the seat out every time you work on it or just flipping it back?

I'm about to take the car into the local dealership to have the software updated to the most current build. I don't think this car has been updated in some time. I just acquired it in the late fall last year, and there's a few messages that need to be dealt with. So I'll get a full Vida/Dice report at that time (I'm sure the dealer will tell me that I need to do all kinds of expensive things...)

I'm doubtful it's a motor issue, as when the controls work, all the features and all motors move as expected. But when they stop working, they stop altogether.

I've taken the seat out of the car, as it is the only way that I could attach the control unit. I can switch out the side switch unit without removing the seat.

Update on the seats working/not working.

If I get in the car and immediately use the controls the seat responds correctly, both base and seat back move. I can continue making adjustments until I'm satisfied. But if I start driving then the seat doesn't respond, and won't until the car is turned off for some time. So for the time being, it's just a quirk that I need to remember. I'm sure there's some good explanation and if and when I learn it, I'll post back.
 
You know, I can't say for sure that I've tried to, for example, adjust the front-back positioning of the seat while in gear and driving. I suppose that Volvo might consider it a safety feature. Let's say you're coming up to a stoplight, foot on the brake, the inertia of stopping is forcing you forward, and at the same time you're moving the seat forward transferring even more inertia through your foot to the brake pedal. I have done that before in other cars and it's definitely not a wise thing to do. I will have to test this out in my car.
