Does anyone know what’s involved with this? I have a family members car that needs it replaced and I located the part but hear it needs to be programmed to work correctly. Any input would be appreciated. The car is a 2011 535i

Here’s the procedure I’ve used in the past. This should be all you need to do as far as I know for a direct swap. You will need E-Sys to do this.


Coding new BMW SZL module (clock spring)

Connect to the vehicle using e-Sys
1. Start e-Sys and connect to the vehicle
3. Select “Expert Mode” on the left
5. Select “Coding” on the left under “Expert Mode”
6. Load the Vehicle Order
8. Right click on the FA and select “Activate FA”
9. In SVT Actual section, click “Read (ECU)”

Inject CAFD
1. Find the SZL_LWS ECU in the ECU tree on the left and select it
2. Click “Detect CAF for SWE”
3. A window will open with the list of options, scroll down and select the latest version
4. Right click on the SZL_LWS ECU in the ECU tree on the left and select “Code”

Appreciate the info! Do you know if I locate a used part if the coding is still required? I heard someone mention they plug and played a used clock spring assembly and they didn’t have any issues after install without coding.

If it has the same options it may be plug and play. I got a used one with the HBA button to retrofit the option to my car. I believe the donor car had HBA from factory and no paddle shifters. I needed the coding listed plus a few extra changes to enable the HBA in other modules to get it to all work correctly.

I believe before I did the coding it all worked except for the HBA button and my paddle shifters, so you may be good to go if the clock spring is from a car that has the same options as yours.

Thank you for that! I was able to source one with matching part #s from a vehicle with the same options it seems.
