Based on the photos in Ebay.UK, they look the same as the US ones.

i was also thinking of buying one without the highbeamassist as they are much cheaper, i have been looking up if there the pcb's inside of the szl's are different from eachoter and i dont think so as the szl only works as a communication between modules. so i will try to swap the stalk of my current szl and solder it to the new one without the HBA or rainsensor depends on wich i would buy. but just to be 100perfect sure that bypassing the szl isnt possible

In my case the reason I cannot run from the bottom of the stalk (where the plugs are) the required power and GND/FEM wires to the steering module, because there isn't a pin there for them. Bypassing that plug and connecting directly to the steering module would work electrically, but not physically, The wire would move/twist/bind with every movement of the steering wheel.

So the only way to jerry-rig it (and not sure it's worth it) is to add two receptive pins in the plug itself, take the stalk and clock-spring apart and run the two wires from those two pins on the inside to the factory pins on the clock-spring plug that supplies power to the steering module. Do not want to risk the ribbon cable's free movement inside the clock-spring.

roxxor could you take a look at these pics of my wiring and let me know what you think?

Hi Meza,

I have the same thing as you. Did you manage to get the heating working without changing the SZL?
Or anyone had the same and managed to make it work?
My part no of SZL says that it doesn't support heated steering wheel but I have the plug for the wire on it and also the wires needed to the FEM already added

LE:https://www.realoem.com/bmw/enUS/partxref?q=61319351145 this is the SZL that I have currently

You can just try out the heated steering wheel. If it doesnt work then get the correct szl.

Maybe I am wrong, but I thought the SZL is the steering wheel electronics control unit. While you have listed the steering column switch part number. If you already have the male heater power/GND pins on the 12-pin steering wheel switch socket, and the power + FEM wires running to them, and also have the heater switch-wire socket male pins populated, then you just need to [U]check the part number of your steering wheel electronics control unit against RealOEM. In my case, I have a base model, and do not even have that control unit installed, no male pins either for the power/GND of the 12-pin socket. So I had to get a new column switch and a separate control unit.

A control unit part number has different configurations where one of them may not show steering wheel heating, but the same part number may have one or two configurations where it does have it.

So I figured it out, had to change the steering column switch. I have the wires in the 9 and 11 in the 12 pin socket, I also had the pins in the back of the steering column switch but I didn't see that in the front one where you plug the heated steering I didn't have any pins. Today I got all the parts and gonna do the retrofit. Fingers crossed!
Thank you very much fe7565

Finished the retrofit, all working good. Thank you for the guide! Just as a note, after I VO coded the car I had to get out of it, lock it and leave it for a few minutes and then it worked. Right after I did the VO Code it didn't want to work.

Just finished installing the heated steering in my bmw f20 2012. It works wonderfull!

Both pins of the wire going in the back of the szl snapped in half in the process but its all working perfectly now. Fuse 144 was free aswell for my model so that was a relief.

So for other people with f20’s, its the same pretty much! The only difference was that the plug mentioned for connecting to a fuse in the back didnt work for me bc there was no plug to get it into.. i used a flat plug sleeve to connect to the fuse. Otherwise it would just fall out.

Is a brand new Airbag really $800 from the dealer? how much would you guys pay a indy shop for this job

Hi there, I'm trying to do the same retrofit and I have the same steering SZL that you have it has the wires already the pins in the back but not In the front. I'm trying and to find the right SZL I need does anyone know what will fit please there is so many to choose from. I have high beam assist on a F33. The X6 stalk looks the nearest match but I've read the heated switch on/off is totally different this is the closest I've found part number wise but they are crazy prices 61319351146

Thanks
Daniel

You just need to find a SZL that has the pins in the front (and the options lika HBA if you have them), that's all. Don't look at part numbers etc because you'll become more lost)

First of all give us your vin or at least which car you have it lci or prelci. SZL depends on your car option so is really stupid to buy "one of this which has a pins".

And you will see that the same part no is listed with heated steering wheel and without steering wheel. What do u do then...

[mrjgonzalez]

I have replaced the steering wheel (twice) and the lower steering column with switch and doen the coding several times. I also replacced the clockspring with a heated one. The switch illuminates and the dash says steering wheel heat activated etcetera. I just don't have heat in the wheel. Any other things I should check?

thanks for all the help getting this far

[TheNine90]

Is there any fault code? You can try testing it using ISTA

Choise right one... Actually you doesn`t have clue why is this so

Did you run the extra power wire? It sounds like the wheel isn't getting power to the heating element.

I have the following SZL with BMW part number: 61319351145
According to BMW it doesn't support a heated steering wheel, but on the back I do see the pins for the button.
And on the front I see also some extra pins, so does this support heated steering wheel or not?

Based on this, looks like it only supports rain sensor and high-beam assist.

Not sure, if your module can be programmed in Esys or reflashed to include the other options as well. But you could replace the module with another one that has the feature you need. May need to run a couple of extra wires. That is, IF the pins are already there in the clockspring/steering wheel switch unit. Besides the steering wheel heater switch pins, you also need the extra power and ground pins here (circled green).





On Ebay USA, the modules are close to the same price as an entire steering wheel with a (matching) module still inside. Example for $90 with module inside (red circle):

Hallo!
You can`t flash SZL on f30 it is not ecu separately. Second thing there is no pins for power and ground(green circle) so you can`t fire up SZL.

Thx, I already found it out, it isn't supported.
