Steering angle sensor - dirty or faulty?
So I've read around about the steering angle sensor or the SZL module that could either just be dirty or be faulty under certain circumstances, but some articles are confusing.
My '05 525i drives perfectly fine. However, at first start and the second I turn my wheel in any direction I get the DCS light and malfunction pop up on my iDrive. Once that happens, my turn signals won't cancel.
I've read that the steering angle sensor could just be dirty and to clean it, but some of the symptoms I have could also mean the SZL module itself could be faulty. Which is it?
005EBA
0094E7
00E51D
00E51A
009CC6
I do have adaptive xenons and the light is blinking, although it could be more than just the steering angle sensor?
Any help/advice would be nice! I would rather spend a few bucks to clean the sensor, than $600+ for a new module.

- Turn signal stalk works, my turn signals just won't cancel after the turn
- Windshield wiper stalk works, manual or auto
- Cruise control stalk works as far as I can tell

From experience it's not worth cleaning. The 05 pre-LCI 9 times out of 10 once a code comes up it's broke due to the design. I would advise you to find one on eBay or the junk yard they are no more than $50. I got one for $50. Install code and set timing.
If you want to check it out prior to just take it out. It's not hard and only takes about 10 mins at most (disconnect battery, pop out airbag, unbolt wheel, remove SZL). You only are looking at the center round piece. The other stuff can be switched over. The cover will clip off so you can see the 2 pins that run across the board. Most of the time the pins break. If the board is dirty you can clean it will alcohol and a-tips but again it's a waist of time. Look at link to see what it look like.

No I do not have a guide written for the replacement. What are you using to do the programming/coding? All you need to do is ensure the wheel is straight, code VIN, and set timing.

I have a driver side airbag malfunction light which an indie attributed to a faulty SZL sensor. I'm looking to replace that myself.
Thanks for you help!
