Question Question about steering angle sensor

Is the steering angle sensor considered to be a module that can be diagnosed with bmw scanner, inpa, or dealer tools?
In all of the above mentioned software products, the steering angle module is listed as "missing/non-existent/not-installed."
Can't tell if its defective and doesn't show up in diagnostics software, or if it is not an actual "module" that I can run diagnostics on.

It's a sensor, not a module. It can be tested but I don't think in INPA (unless you write a custom script for it). You need DIS or ISTA.

Copy that.

Does angle-sensor come as a module on other bmw vehicles that can be diagnosed with pa soft 1.4? PA Soft 1.4 lists module LEW for steering-angle sensor, which made me think that it might act as separate module rather than just a sensor.

Sorry for bumping this...

So I fired up DIS and even tried ISTA (Rheingold), but neither of them see steering angle sensor on my car. That also includes BMW Scanner.
However, when connected to my dad's E39 steering angle sensor is detected by either diagnostics software.

What is even more odd is that there are no errors or lights on my car that would suggest issue with steering angle sensor. It's like the sensor is not there but modules that use its data simply don't give a ****.
Hell, even unplugging the steering angle sensor doesn't throw errors or lights on my car o.O

Unplugging it should throw the DSC yellow cog on. I know that if the steering angle sensor is not calibrated right (meaning off center) it will light up DSC at times. PA Soft is how I found what was going on and yes its the LEW module. I just recalibrated it.

It wasn't throwing any codes when I unplugged it on my car
What I did find is steering angle is always being reported as "0" (INPA DSC), and it stays like that when steering angle sensor is unplugged.

Found it by accident today while cheeking other modules, and yes turning steering wheel does not change the angle read by the car. I guess it also explains why DSC is so restrictive when car is about to slide

Could be just a dead sensor. Check your fuses first though.
