Hello my fellow bmw enthusiasts.
I have a bit of an issue with my 06 330xi

THE ISSSUE
The DSC and brake light are on. The air bag and seatbelt light comes on/off randomly while driving. The wipers work but will shut off randomly and not come back on until I shut car off. The blinkers work but wont shut themselves off while turning.

WHAT IVE TRIED
I first tried just clearing codes (carly) and recalibrating the steering wheel sensor. The codes would go off dash and work until what would seem like when car uses start assist and light will come back on.

This did work so I attempted to clean the steering wheel angle sensor using this post here

My disk looked clean but I cleaned it anyway along with the reader using 70% alchohol. Possibly some scratches in the disk and it seems a little loose.
I put everything back together and reset codes, recalibrated sensor and codes went away but when trying to drive the dsc light would flash and hesitate the cars ability to drive until all lights came on again.



FAULT CODES IM RECIEVING FROM OBD










How do I determine the problem from here?

Where do I go from here? Is it a faulty SZL or is it just the sensor and how does one go about determining that? I hate buying parts I'm not certain are going to fix the issue. Any help on what steps I should take next to get this issue resolved would be amazing.

you have to post codes here

I have updated the original post with pictures of my fault codes. Any help or direction would be greatly appreciated

I have used steering column in my cart ready to purchase but I know it needs to be programmed to the vehicle so I'm skeptical on purchasing it then paying for alignment and programming with not being 100% positive that's what I need.

Any input could be useful to me or others in the future. Thanks for your time.

No one has any input? Bump

i think that there is problem with DSC module under hood or it's communication with car ove PT-CAN or K-CAN because symptoms in first post mean much more than streering angle sensor
since you have used car without warranty you need either replace suspicious modules or get oscillograph to diagnose CAN-bus operation and find which module have problem with CAN-bus

This would seem logical. I've open the steering wheel 3xs and its clean as a whistle and looks all intact (even inspected contacts with magnify glass).

I just ordered the pro K+D-Can from bimmerGeeks

Should I be able to further diagnose the issue with this cable and software?
If so how would one attempt this?

Thus far I've always been to scared to attempt these things and brought my car to dealership but my financial situation lately has me unable to do so and I feel confident I can do this myself just dont want to throw money at the car and pray.

I really appreciate your time 😁

the cable will help you with modules replacement adaptation
but i also suggest you to check if there water in engine compartment boxes, one with Engine ECU on passenger side and one where DSC located

In the same boat, did you get to the bottom of this?

Also wanted to ask, which part number does one use to match with other SZL units? There's a bunch of stickers on the actual szl module on mine.
