So if I haven't seen it in the i-drive...?

But see it if I read codes?

Steering angle sensor DIY fix - it worked

Good question. I must say I was a bit lazy and did not do what I normally always do: read and clear codes after I complete any work on the car. I can do it tonight and report back. Stay tuned.

_____

Update. Yes, of course there were related codes:
005E43: DSC: Steering Angle Sensor Adjustment
005FF7: EDC CAN message (steering angle) from SZL (Note: This is what causes the seemingly unrelated EDC error; it needs steering angle input to function)
00A85D: SZL: Steering-angle sensor
00D373: Message (steering column switch cluster 0xC8, 0xC9) missing, receiver DSC, tran (Probably because it went offline on PT-CAN after detecting the fault)

I cleared the codes as should everybody else after this fix. My issue is completely resolved.

BTW: read out with ISTA/D. A normal simple code scanner might not report these as these are not DME codes.

Would someone be so kind as to ask shuriki to rehost his pictures on the first page? I don't seem to have enough posts to send him a PM.

Thank you..

1) Park the car. Make sure the wheels are strait. Disconnect the battery in the trunk.
2) Remove horn/airbag. There's a hole under the steering wheel. Insert a screwdriver or allen key (size 15-20). Find correct position, slightly moving the screwdriver back and forth. Then push the screwdriver upward to release the inside spring. First time it took me several minutes - I did not want to break anything.



3) Disconnect the horn/airbag. Gently push the tab with you finger or screwdriver, then pull to disconnect.



4) Remove the steering wheel bolt. Use 15mm 6 point socket (12 point socket is not very good for this). I don't know how to lock the steering wheel, so I needed second person to hold it while I was undoing the bolt.



5) Remove the steering wheel. Disconnect the wires by pulling the connector out



6) Remove the cover from the cowling. I did not use any metal tools here. Apply finger pressure and pull the cover towards yourself.



7) Using T10 Torx key remove turning signal, cruise control and windshield wipers controls.



8) Remove the bottom cover of the cowling. There's plastic screw on the bottom, be careful when removing it. Then apply finger pressure to the top cover and pull the bottom cover down. Do left and right sides separately, one at a time. Leave the bottom cover hanging down. Don't remove the top cover.




9) Using T15 Torx remove 6 screws. Then carefully pry big tabs on each side to release the big round module. I could not remove it completely until later, as the wires on the back hold it.



10) Remove SRS module ($545+tax at the dealership) from the brackets. First pull the bottom part out, but not completely. The wires behind it at the bottom are still holding it. Then wiggle the module out from the brackets. Don't rush - find a way that works.



11) Disconnect the wires from the back.




12) Now I was able to separate completely big round module from the SRS module.
Using T8 Torx remove 4 screws. Note the arrow alignment for later - when you're putting it back together.




13) At this point you could clean the disk. I took it out completely - wanted to inspect the board and it is more convenient this way.
Remove two T6 torx screws to disconnect ID Led cover. It's slightly yellow-ish. Cleaning did not help.



14) Release the tabs from behind to remove the disk. Use your fingers to slightly push several of the inward at the same time.



15) You probably can feel some sticky goo on the top of the disk with your fingers. Clean in (I used oil-eater with water), wipe it dry (I used cloth that comes with eye glasses).

16) Put everything back together. Don't forget to align arrows from step 12. Connect the battery, start the car. After the dreaded yellow AWD, break, stability control lights come up, turn the wheels all the way to the left, then all the way to the right. The messages disappear. It's been almost a week for me and the message has not re-appeared.
I didn't see any picture. Can you help ?

New here got my Beast about 3 weeks ago. 2008 M5 with 61k miles. started getting the xmas lights about a week ago with the addition of the Check Battery terminal error. The errors disappears every time I shut down the car for a few minutes or sometimes will clear out by itself with continuous driving. Did clean the SZL unit today and error showed up and quickly disappeared during driving.

Error still continues while driving and clears up within seconds to a minute. I will try to clean it again one more time this week. I also did reset my TPM after doing my initial cleaning. Any tips would be appreciated.

Many thanks to all who have contributed to this post. I have a 2006 650 which started throwing sporadic active steering malfunction warnings and AS resets. Lately, it began throwing warnings as soon as I turned the steering wheel to the left. Used the info in this thread to disassemble, clean and reassemble the components. Working like a champ. On the disk in my car, there wasn't any real build up of contaminants. Just a very small smudge of what looked like dried grease. Again, thanks for all the great input.

Just checked it again after two weeks and guess what? the crystal like stuff is back again. I thoroughly cleaned it this time and used a low heat blow dryer. wash, rinse repeat. So that cleared up the errors. Also I found out that my voltage regulator needed to be replaced so I did it all today.
