2003 heated seats - what do I need

[rwinstanley85]

Think I posted this in the wrong forum previously.

My 2003 has all electric seats from a M3. I want to put heated seats in. What do I need ?

The facia button panel - I can get off eBay.
The loom is in place .

Where can I buy the heating elements / what part am I looking for ?

Do I need anything else to get the job done ?

Thanks

Watching this with interest - I might do a retro fit myself

I suspect that will be quite a project. I am sure the heating elements are embedded in the seat material itself so you would have do de-glove the seats for a start. I also suspect it will need heavy duty relays as the seats draw a fair current. Button would be the least of your worries.

Quicker & easier just to get some heat seat pads from Amazon for the winter.
