Does anyone know how to test the "steering angle sensor" and how to figure out if it is faulty and needs replacement or if it needs special calibration conditions.
Can I clean the sensor without dismantling the steering column?
I have to mention that I have a little movement in my steering wheel without moving the wheels.
What interface/software should I buy to calibrate the sensor properly?
INPA , PA-soft? Which version?
You are right. The sensor in on the steering column. I have never seen one, so I don't know how to adjust it.
However, you should not have any free-play (what we call it) in the steering wheel. Also, the steering wheel should be "centered" when driving straight ahead. Many shops don't heed this and the steering wheel position is off to the left or right and this is not cool for the sensor to work properly. It also drives me nuts, to not have a properly aligned steering wheel. Don't let them try to just remove and reinstall the steering wheel in another position. There is a definite "center" position for the steering column.
If that is all they do, your car will not track straight.
I would recommend a HIGH QUALITY alignment shop to do a complete alignment. Even the dealer can screw it up ... happened to me on my 528e (sold). Don't accept the car until you have driven it, and verified the steering is straight.
