Hello has anyone got or knows where I can find the heated seat retrofit pdf?
Only need the wiring diagram
Thanks

[Ti Rich]

same here, need it too

[75fusca]

I need this for the retrofit of my rear seats. Have the OEM heating pads and real console fascia with buttons, now I need the connection diagram and connecting loom part number.

Hijacking the thread; 75fusca where did you get the pads and buttons from; I would like to do my rears...

I got them at the BMW dealership.

HEATING ELEMENTS:

Check part No. depending on whether your car has thru-load backrest system or not.

SWITCHES:
Switch, seat heating, left rear part No. 61319163292
Switch, seat heating, right rear part No. 6131916329

CONSOLE FASCIA:

Check based on the colour of your interior (Black was the only available fascia last summer).

So, once you have all these parts the question I have is: How do we connect them?? Is there a specific loom like in previous models?

Cheers,
Martin

wow...nice, i would love to have that feature add as well. Hope you guys find the solution

I've got the wiring, fitted the panel, coded etc. The power to the seats is easy enough just need to know where the single control wire goes to the REM.
I'm just going to have to bite the bullet and pay for access to bmwtis.com

[beema_geeza]

Success!!!!!!!!!!
It's cost me £20 for a 24hr subscription on bmwtis.com but I now have heated seats!!

[tboooe]

CONGRATS!!!! Now post some pics!

[Sladester100]

I saw the diagrams... Looks confusing lol

You do front and rears?

[beema_geeza]

Just front I don't think there's an actual retrofit pdf for either, I couldn't find it anyway. I looked at the rear diagram while looking for what I was after.
They would be simple to do like these were.

[beema_geeza]

I bought Msport leather with everything already installed so it was just a case of new climate panel, 3 wires to each seat and coding.
I ran 2x 12v from power distribution box under the bonnet, fuse 64&65 to seat plug X14*1b pin 25 and earthed pin 26 locally. I ran a single wire from X14*1b pin 8 on both seats and spliced together for linbus to the REM plug A174*14b pin 18.
Added 494 to VO and coded all ecus.

[beema_geeza]

Little bit different to mine. I don't have electric seats only bolsters so mine don't have or need Can wires. This is the diagram for my drivers seat module

So the actual 'heat pads' were already there too?

Sorry to be a thread necrmancer - but I recently got my F30 335ix and wanted to know if anyone has gotten the rear seats retrofit to work out. I'm annoyed that here in Canada, this isn't a standard package for 2013 and I would love this for my kids.

I have the parts list from earlier in the thread, so that's good to go.

However, I have a few more questions:

1) Was the wiring harness for the back seats already there, or do you have to get that too? I don't see a part number in RealOEM - the harnesses for the back seats are greyed out.

2) How do you wire up the rear seat heater buttons to work? Is there a harness tap in under the centre console? If someone has a pinout already it would be awesome if you could share.

3) Is there any programming involved?

I had looked into this as well, I have the Front Heated Seats and thought about doing rear, but there is no pre-wiring in my car that I could find. For rear seat heating, you would need to replace the seats as well as add a module for each side(driver and passenger), and replace/add the buttons. All the wiring for the rear seat heating runs to the REM module in the trunk, and you would most likely need to code it to enable the heating function once everything is installed.

See this page for the modules:

Thanks for that. I forgot that there would be controllers for the rear seats too. But they're $250 each

The harness that I was hoping was there already is the one listed as #3 and 4 here.

http://www.realoem.com/bmw/enUS/show...diagId=61_2970

But it looks like the bill is climbing rapidly...

[roxxor]

Maybe $250 each if you buy new, there are some in the $65-85 range on eBay right now lol

Anyone happen to get the part number for this wiring harness before realoem crapped out?

[SMiGGs]

The heating element is there for the two front seats already? I have a loaded Msport like OP, but no heated seats.

If so ill purchase a new climate control right now.

Interested in the wiring harness part numbers if anyone has them.
