Hi all, I'm hoping someone can help. I have a 2003 996 with standard heated seats (NOT the sport seats, NOT the comfort seats). I need to replace the foam in the bottom seat cushion.

I've searched here, I've searched the usual parts suppliers, and I've gone to the Porsche dealer parts window, and I haven't been able to get one definitive answer. I think I need one of these two:

996-521-525-00 "Seat Cushion, Seat, Foam Part- Without sport seat, with heat", or
996-521-521-01 "FOAM PART - SEAT CUSHION - WITH HEATING"

Does anyone know the correct part number?

The seat heating element still works fine, in case that's relevant.

Gratuitous pics included.

 

Oh, and if it's not either one of the two I listed please let me know! Thanks, all.

 

The seat heaters are bonded to the foam and cannot be removed.

The .01 part is specified for 996.1 cars.
The .00 part is specified for 996.2 cars and is twice as expensive.
I have a 996.2 and used the 996-521-525-00 part to replace the seat foam. It fits and works but looks a little different under the leather, the edges are sharper somehow. Or perhaps the old foam was crumbling to make the edges rounder.

 

Hey 4strings, where did you get the clear 3rd brake light?

 

If you look at this it seems these are the numbers
99652152101 is up to 2000 with heating
99652157100 2001 and up does not specify heating but does indicate that the heating element can be purchased separately for 2001 and up.

The IXSU numbers are thinner to give more headroom.

This indicates without heat for the 99652157100 so I would order the 99652152101

 

No idea! It was on the car when I bought it. I've seen similar on Amazon and the 'bay.
