[F10,F01] Steering wheel heating retrofit

Hello

I have fitted a heated M steering heated wheel on my 2010 F01.
Added heated button as well
Checked ETK and there is not any differences between slip-rings SZL just with or without High beam assistant
However when connected ISTA/P Ista wants replace SZL as well which I done (9220834)
Added option to VO 248 coded SZL button is lighting but steering wheel not heat
Tried different CAFD files inject to SZL but no luck
I don't think there is any additional wiring connected to SZL

Did anyone add steering wheel heating to his unheated car? What else has to be done to get this to work?

Any help would be much appreciated.

Thanks A Lot

I have done this retrofit. SZL has different part number when heated steering wheel is installed from factory, so you can't use ista/p to code it. You must use e-sys. It depends on your old setup if you already have power supply for the heating. If you don't, you can use free pins in SZL to pass through supply cables (+12 v and ground if I remember correctly). Check wiring diagrams from Rheingold.

Edit. You already replaced SZL (which is not necessary), so check wiring diagrams and use original pins for heatin supply. You could have used any free pins from original SZL.

I did not used ipta/p to code it just when connected up ista/p wanted to replace unit which I done
I using esys to code and reprogram as well
For me strange is that all pins in SZL are reserved (busy) and no any pins are free left with heating or without that option
so where to connect two additional wires?
cant find in wds correct diagram

thanks

You can't use WDS, it doesn't have f-series wiring diagrams. Rheingold has them.

Ok, you have F01, I did this to F11. For F1x there is for sure a wiring diagram available.

to which pins you're connected that two supply pins
top socket is for airbag the bottom responsible for heating

My old steering wheel didn't have steering wheel module and the new one with heating had. This module is connected to connectors A92*4B (two wires, power supply) and A92*6B (LIN bus and ground). The latter was available so I just connect two wires there. A92*4B was not available so I used two free pins in connector A92*3B (airbag, see steering wheel side wiring harness and you know which pins are unused). I of course had to pull wires from junction box to the backside of SZL, to two specific pins that lead to this airbag connector (I used multimeter to determine the pins). You are missing these two wires. As you have replaced the SZL, you can connect them as they are connected on wiring diagrams. You can find wiring diagram from ISTA with search "steering wheel". Now you really should be able to do it.

Edit. Remember, I did this for 9/2011 F11.

Edit2. You can find power supply diagram for SZL with search "steering column switch cluster". There are the wires you are probably missing.

No, they are powet supply wires for steering wheel module, for both heating and vibration.

I don't know about F30 heated steering wheel, I ordered it from factory. Wiring diagrams can be found from Rheingold though.

I removed base of airbag, and you're right lin bus and ground are present, moreover, it was enough to look best your photo.
I bought two years ago on bay the steering wheel, new... from factory
maybe... were discarded because the module was broken

I have also fault don't remember now but similar like yours

Don't think so both are faulty?
maybe need to swap cables in the 6 pin plug
I cant read rheingold WDS
need to compare with and without heating diagram and spot the difference

If you retrofit stearing wheel heating on a car that did not have steering wheel module (Vibration in steering wheel) then you need new SZL and add cables from SZL (A92 1B Pin 11 ground and pin 9 +15) to JBE
If you dont change to new SZL, then its possible to use free pins in A92 3B like AP90500 suggests in post #12
