I would love to find way to be sure before buying new steering wheel that will be amazing upgrade (from your experiance), If you have any advice on how to check, I would be very grateful

Check part number in realoem or you can also inside the steering wheel behind the airbag where there are connectors.There will be 4 wires coming into the Electronic steering wheel module at the bottom right around 5 o'clock

Thank you very much for your reply , I hope that is the way to make sure that I don't need to change SZL

Hi guys, Will retrofitting the steering wheel void my warranty?

Can you also advise how do I disconnect the battery to replace the steering wheel? The reason I'm asking is on the some videos people are disconnecting 2 batteries.

[TheNine90]

It will most likley void the warranty.
It better to disconnect the battery since you need to disconnect the steering wheel airbags.

[marbab]

Thanks. If I just disconnect "-" would this be ok?

[TheNine90]

Yes. Let car sleep for a while then disconnect the battery.

[marbab]

Thank you. Can car go to sleep with the boot open?

[TheNine90]

Its possible. The main thing is that you shouldnt disconnect battery immediately after turning off car. Let some of the modules sleep.

[marbab]

Many thanks.

I am considering extended warranty, but also would like to retrofit the heated steering wheel. Is there any chance BMW will code the retrofit steering wheel if I change it?

Is there any chace they will see if someone else codes it for me?

The retrofit will likely void your warranty. I dont think the dealer can do this retrofit for you, you can try asking them. If not i can code it for you.

If they just scan the car without programming they shouldn't notice it. But if they program the modules then some errors will pop-up due to incorrect LIN components, and if you changed the steering column module it will appear as incorrect hardware.

Thanks,
I emailed BMW to find out. I had quite a few issues in my 1st year of using my car. Luckily it was covered with warranty. I believe it's really worth to do keep it, but at the same time would love to modify my steering wheel (already bought ). Just trying to balance it somehow. Hoping that only some part of warranty will be affected (i.e. programming etc.) and others won't.

Hi guys. I have just got a M340i with the 690 part number steering wheel (m sport and paddles without DAP)

What hardware do I need to change to get a heated steering wheel. From what I have read I think I need the 691 steering wheel but not sure if that’s right and if I need anything else.

Thanks in advance

Need correct steering wheel(32308746691) and Steering column Switch

Thanks! What switch would I need? Do you have a part number or anything?

[TheNine90]

There are multiple part number for different packages. You can look it up in realoem and filter them according to the vehicles configuration or send me the VIN i look it up for you.

Thank you so much. I had a look on realoem but I can’t be sure which!

This is the vin for my car WBA5U92080FJ14804. Really appreciate your help

It looks like the SZL for steering wheel heater and non heater are the same. You can use same one. Check the part number

[koosha10]

Thanks for you help! I’ll get a steering wheel ordered and report back if there’s any trouble

I tried searching realoem but having problems. I have a 2021 M340 with drive assist only not Pro. How do I determine what I need to add heated wheel?

Vin: M8B57550
My wheel looks like this:

[TheNine90]

First you will need to change the steering wheel with one that has steering wheel heater.
Looks like you have the correct SZL. This is the current one im seeing using your vin.
Switch unit steering column (US 4B AIC FLA)
4_Band: Steering wheel heater
aic: Rain sensor intermittent switch (auto interval control)
fla: High beam assist (switch)
