If you read to the bottom of the second page of the SS link somebody chimes in regarding a P2 V70 saying they had success.

I personally have only gone the other way & swapped non-heated seats into a P2 that had provisions for heated seats. Currently my wife is insistent that I undo that.

Did you reach out to Yagger? If there is a way to do it I’m pretty certain he knows how to make it happen.
This is my thinking too. It seems doable but not worth the effort. Not even for a 95k P2 V70 2.5T. There's a bunch of those around right? Npw, if it were a manual ...

It’s like buying a a Volvo without a sunroof, it’s just wrong
So is this. Volvo should not have let anyone order the turbo models without heated seats!

OK I had a correspondence with yagger, to summarize his info and from other links i have seen, here's how to do it:

(1) Get the hardware, junkyard is your friend
1a . Heated seats
1b . CCM with buttons or swap the buttons from a CCM that has them into your CCM that doesn't.
1c . Seat heater modules - SHM in wiring diagram. These are attached to the heated seats you get from the junkyard or you could make your own based on other postings.
1d. Wiring - I am assuming all cars have the wiring but I don't know this. Anyone know?
1e . Add two fuses to the CEM

(2) Program the CEM to activate heated seats. Yagger can do this, there are three basic ways they do any programming:
2a. Option 1: Send them your CEM, they change config as you wish (in this case add heated seats). You pay them for the reprogram and you pay for shipping both ways.
2b. Option 2: Buy their OBD device, they send it to you and after you receive it they use it to get the CEM pin live/online and change the config as you wish, through OBDII using your DiCE. This way you don't need to remove CEM.
2c. Option 3: You figure out how to extract the CEM data and send them the data by email. Then they make the CEM changes live/online through OBDII using your DiCE. Again this way you don't need to remove CEM.

The 07 CEM is a pain to remove but the videos from Xemodex make it clear and seems not very difficult. I would probably go 2a unless someone can talk me through 2c.

Thanks also for explaining that for my 07, the CCM would have to come from 05-08 car.

Both actually. It same platform. I mean S80 1999MY.
For cars like V/S70 there is one CAN only.
