996 seat heating elements in 997 foldable seat

Recommended Posts

Hi all,

 

Sometime back, I installed a pair of 997 foldable buckets in my 996TT. Whilst these are superb, I lost the heated seat function of the original Comfort seats. As the car has this option (M342), all the wiring and control units are there, I thought I could add the heating elements into the 997 buckets, reusing the wiring, switches, etc.

 

Did anybody try something like this?I have identified, with the help of rosepassion.com, the heating elements, as per PET for MY02 996TT with M342, i.e., left/right heated seats.

 

I'm intrigued with the fact that for the bottom cushion, there seem to be 2 elements, one below the cushion and another on top of it, integrated with the cushion. In the 2017 PET, sheet 817-05, these are items 8 (996 521 531 01), 9 (996 521 525 00) and 16 (996 653 105 01) as per the photos attached. I don't feel like tearing my original Comfort seats to find out the details and am wondering if anybody had experience with repairing their seat elements and can confirm whether all 3 elements are used and are installed like it seems from the PET illustration:

 

- Item 8 installed between the backrest cushion and the leather cover;

- Item 9 against the leather as well;

- Item 16, beneath item 9.

 

As to plugs, do all 3 elements plug directly into the sockets of the wiring harness underneath the seat? From the photos, the cables seem to be long enough for that purpose.

Well, after my own digging, I found that the seat bottom cushion does not have a heater integrated, although it looks like it does in the photo above and also in the parts catalog: the illustration shows it with a lead and a plug dangling.

 

So, to go ahead I just need the two mats, the two cable bundles from my original seats and the two control units and most importantly, find a way to fit the mats into the seat cushions which may not work, given they are segmented. Am investigating that.
