seeking BMW electronics expert for heated seat issue

hdrewh · 12-22-2010, 02:55 PM

Short story: my car has premium, non-ZSP, and without the heated seat option. I replaced my seats with premium, sport, *heated* seats I had the car coded to add the heated seat VO. Driver's side heat works perfectly (even before the coding), passenger heat does not (everything else about the seats works fine).

Obviously the car was built wired properly for the heat to work on the driver side, but for the passenger side, either not wired at all or some other issue.

The heated option was a bonus as my primary goal was to get sport seats. But since they're heated, and driver's side works, I want to see what I can do about getting the passenger side working as well.

I'm decent mechanically and basic electrics but not when it comes to analyzing schematics, the CAN-bus or anything like that.

Willing to pay an experienced BMW technician with deep knowledge of electronics for their time to look into what specifically is needed to get the passenger side heat working. Retrofit kit is not an option. Its Euro-only and a huge PITA (see HERE).

PM me if you're interested in working with me on this or know someone who might be. Someone relatively local would be great.

Thanks.

Im sure this sounds dumb. But perhaps the passenger seat heat pad has a nipped wire or is broken? Just a thought as sometimes the obvious is often overlooked...

no idea why my side bolsters have stopped working when i fitted the heated sports interior??

also is the harness that comes up from under the seat different on heated cars and those that are not? in that case will those two harnesess (one for drivers and one for passengers) need to be replaced too?
