Heated Seat Issue

Hello,

I have a 2019 i3s that has as an issue with the heated seat on the driver's side. When I press the button, the lights come on for perhaps a few seconds (you hear the solenoid or relay click), then it turns off (and you hear the click again). It will not come back on after that unless I reset the vehicle (turn off and restart).

Has anyone experienced this?

Thank you.

I've not, but it sounds like you have a short, and the overload is tripped. From your description, it sounds like it self-resets, but only upon a vehicle power up.

Other than checking the plug is fully inserted under the seat, it sounds like a trip to the dealership.

I have the same issue and on the same side. Mine is a 2014. I'd agree that it's a short. I would take it to the dealer and can you please report what they find? I'd love to fix mine without a trip to the dealer.

Hello.

As promised I wanted to give you an update.

So I got the car back and the service tech found the following:

FAULT 804613 SEAT HEATING: DRIVER BACKREST HEATING PAD LINE OR SHORT BREAK TO B+; FOUND DRIVER SIDE SEAT HEATER FAULTY
(D5210_00000000_66_001)

REPLACED DRIVER SEAT HEATING ELECTRONICS.

Hope that helps

De verwarming van bestuurderszitting van mijn i3 viel al een tijdje steeds na 3 minuten uit. De auto gaf geen storing aan. In het volle vertrouwen op BMW zag ik het een tijdje aan. een storingsmelding bleef uit. Afspraak bij de dealer voor een analyse. Uw zitting heeft kortsluiting. Moet vervangen. Kosten 400,,--. Bij controle op de kapotte zitting bleek de aansluiting van de 12v kabel gebroken. Te weinig flexibel/te kort.

I just started having this problem intermittently. It looks like the element and seat cushion are one piece and there is also a seat module. Both can be tested with a multimeter.

When checking the broken seat, the connection of the 12v cable was broken. Too little flexible / too short.

Hi. Thanks for posting this. I don't suppose you know what Heating Electronics he was referring to?

No unfortunately I've no other information regarding what they did.
