Does anyone know if this will work on a 2017 X5

Ah I see thank you

So right now what I have is;

F30 320d 2012 with Non Heated Standard Wheel (it has cruise/auto lights / rain sensor etc)

I have purchased a heated M-Sport wheel, airbag, and also the lower plastic shroud which has the heated wheel switch inside, as well as the cable coming from that switch to be plugged in somewhere.


Is it a case of connecting the wire from the heated steering wheel button (white connector) to the spare power parts of the airbag connector, refit and code and that's it?

Not really like that. Be sure the wheel is complete with ecu for heating function, this ecu must be powered through the airbag connector, then connect the switch cable to the appropriate socket in the ZSL and code adding the option in salapa and CODE all the requested ECUs

Tea & Biscuits,

There's more to it than that i'm afraid.

You need to run a new 12V power supply to the SZL module, this passes through to the spare pins on the airbag connector wheelside. Then you need the wheel heater controller module (not supplied with a new wheel) this fits in the wheel and connects the new power from the airbag connector to the heater element and controls the heater current / temperature via the feedback from the thermistor embedded in the wheel heater element.

This wheel module connects to the LIN network in the wheel and controls the heater.

The wheel heater switch connects to a socket on the SZL but it does not control the heater itself, it sends a signal to some other controller which signals back over the LIN network which comes back to the heater control module in the wheel.

There's a bit of fiddly wiring to get the 12V into the SZL, you need the special miniature socket pins to fit in the connectors. The you need to get the supply from the wheel side airbag connector to the wheel heater controller. which needs DIY leads making up.

When you code it then it will work (hopefully).

Ahhh I see, may need help then lol

The wheel I bought comes with the heater controller module inside it as it was a second hand wheel they included that module free with it thankfully!

must displacement connectors power and ground to the heated steering wheel

Has someone got the part numbers for the white plug and 2 wires and pins?
That's all I need to hook mine up now. Just need those bits to connect to the heated module. Thanks in advance.

Vinny, if you go back to post 23 you'll see the picture of the connector assembly I used to get from the airbag connector to heater controller.

These are all BMW parts. You buy the green 4 way male plug and that fits onto the black socket on the controller.

Then the pins / sockets come pre-crimped on lengths of wire that you cut / solder together as required. You have to open up the 6 way air bag connector and insert the new pins into it, then close it back up.

You'll also need two more wire sockets to go into the connector on the back of the SZL to bring in your 12v supply.

I'll try to dig out the part numbers.

They are MQS pins / sockets as below: (they come with wire attached). I used 0.75sqmm throughout which is plenty, items 1(socket) or 3(pin)

Then this 4 pin male plug body will go onto the black socket on the heater controller:

Awesome cheers
My car is top spec with lane assist, active cruise with distance etc so do I still need to run wires to the szl? Cheers. Need the heated wheel on with today's weather haha. Also I saw the white connecter with the 2 wires, that's what I wanted to buy, the wires and white plug. The green plugs confused me as they were green so wasn't sure if they were the same as the white one.

[doughboy]

That's easy then!

If you have lane assist (vibrating wheel) then you have the power already in the wheel so you don't need to do anything! It's the same supply for heating and vibrate.

The single wheel controller unit does both functions (provided you have the right one), you need the one that does heater & vibrate, then it will just plug straight into the correct wheel socket A83*4B, code it and you're away.

Your existing wheel controller will be for vibrate only, you need 3rd item 03 here:

All this pesky airbag fiddling is only for cars that DON'T have lane assist...

Awesome news! Don't even need to get power from the airbag to the controller? 😁. I checked my part number and it crossed over to the one I need apparently as I pulled the airbag out the other day to check. Cheers for the help. 1 last thing haha, where do i buy the software from for coding? Insta/ esys. I had it years ago or e90 but on an old laptop. Usually get my mate to do it who's bm specialist but hate meithering him lol.

[doughboy]

No, you have the correct power already in plug A83*4B as it is used for the vibrate.

You'll need a new wheel controller 61317848640 for heat & vibrate.

The one in your car as it stands should be 61317848639 vibrate only.

Just get the new controller above, fit it along with the heated wheel away you go. Oh of course yo need the heater switch which plugs into your SZL module too.

You'll need esys to code it. Just enabling wheel heating in a few places.

Appreciate this so much mate. Cheers.
Yer I've got m3 heated wheel and covers, lower steering column cover for the switch and the switch with switch wire. Will get esys and get it sorted over next few days. Thanks a bunch!

[vinny88]

This is going to sound really daft.... but I think my steering wheel fitted to my car already may be heated. Am I right in thinking if it has the black and brown wires with a white plug coming off it on the right hand side then it is?!?. I'd upload a picture but im a newbie so i dont know how 🙈. Its a 4 wire white plug 2 thin black wires, then a thicker brown and thicker black wire. If so my car had a heated wheel from factory but no actual switch/cowling etc.

[doughboy]

Yes, the heater plug has 4 wires. 2 for the heater and 2 for the thermistor for heat control.

There's no way the factory would deliberately fit a heated wheel to a car without that option. Have you had your car from new?

Is this supposed wheel heater plug plugged into the wheel controller module? If so you must already have the right module with the connector for the heated wheel?

Photos please!

This is why I say it would be mental if so. I got it off a guy who had it from brand new, I actually mentioned about the wheel not being heated when I bought it and he said if it was an option he would have chose it because he lived in scotland but it wasn't at the time. He pretty much chose every option on the list except sunroof and elec seats. How do I upload pics? Sorry for asking lol. Yes it's plugged in. I've actually just removed the outer trim just to have a better look at the module. It's all connected up.

Ahhh my pictures are on my phone not a hosting site. I'll have a mess around later and also look at my new m3 wheel to see if wiring is the same (i.e the heated bit).

[doughboy]

No need for hosting site. If you login to this site from your phone you can upload from the phone.

I've uploaded 2 pictures to a public album on my profile. Let me know what u think. Cheers

[vinny88]

My brand new m3 wheel is the Same. I can confirm my car has come with a heated wheel from factory but doesn't have the button or cowling. It has never been changed either. Very strange! Just a case of the switch, cowling and coding. Although I'm fitting the new m3 one anyway. So now I've got a heated m sport wheel for sale haha

[TeaAndBiscuits]

So if I buy a SZL steering slipring thing that has the heated wheel functionality already I could skip the extra wiring bit too? Just thinking aloud?

No, even if you buy an SZL with heater/vibrate supply pins fitted (only 1 replacement SZL is listed and it has all functions fitted) you still won't have the 12v supply wired to the SZL. But you will avoid messing with the airbag socket wheel side.

SZL is very expensive however..
