I am playing around with after market seat heaters in a 928. About 11years ago, there was some discussion about this. Anyone tried this recently and if so, which did you use?
Thanks

Bump for additional interest on my part.

Contact Paul Champagne. He said he can supply me some simple to install heaters when I get the seat covers from him.

Well, I already have upholstery. Who is Paul Champagne?
Thanks

I would bet you don't have to buy covers. I just mentioned that I will get them when he has a chance to make my new covers.

I replaced the OE seat heaters (late model type, with OE seat heaters and supple leather) with aftermarket 'carbon fiber' seat heaters last year for my '94. It can be done, and the results are good (used everything except the resistance heaters that came OE - that is wiring, switches, etc.). The aftermarket ones do not heat up quite as quickly, nor get as HOT as the OE ones, but they are comfortable in about 90 seconds, and stay that way as long as the switch is turned on.

In order to do this, you will need to completely dismantle the upholstery. IF the seats had OE seat heaters, they must be removed, and they are REALLY bonded to the foam. While I was doing it, I installed new foam in the lower seats, but not in the backrests.

Thanks. Your seats look good. Still not sure how you got the heater pads to conform to the seat bolsters and not be visible through the leather. Maybe I am missing something. FYI, I did not have any original heaters to remove.

Later cars have different seats that make heaters easier. The problem is with the early cars and the humps in the bolsters that have to be held down.

Not sure how late you are talking about. I have a 1988 S4. Also a 1982 Euro-S. Don't see much difference in the seats though. Thanks

Pantera928,

IF you decide to install the seat heaters, and want to keep original type switches for them, I do have at least one switch that has the two 8 ways, then a seat heater switch, then the stock blank where the lumbar switch would be.

Forming the seat heaters so they don't show through the leather is NO problem. The new carbon fiber ones are relatively thin, flexible, and easy to install. You have to cut out sections that into the 'pleats' area of the seats, and lightly bond the heater fabric to the foam in the raised sections.

Thanks. That makes sense but you have to keep them connected somehow between the raised areas. How would you do that? Sorry to be so obtuse and I appreciate your patience.
I have an aftermarket heater from Seat Comfort that is my test mule. Since I don't have rear A/C, I bought a console insert for rear A/C and am putting the switches where the rear controls go which will give it a factory clean look.

Gary Knox

You leave the two edges 'connected, and only cut out the center parts, about 1" wide where there is no 'raised' foam area.

By the way, if you do decide to do this, BEFORE you start to re-assemble, drop me a line about a better approach than hog rings for putting the stuff back together.
