Mein Auto: 2006 BMW 650i
Throwing ACZ error... Steering wheel sensor

Ok, so I think I messed up the calibration on my ACZ on my 2006 650i. After a DIY brake pad job i was troubleshooting a brake sensor error. I entered the dash menu by holding down the trip rest button, and as I was cycling through the menu I must have accidentally changed a setting in there. After i restarted the car, the traction control light + BRAKE light warning appeared.

From what i have read i have somehow killed the ACZ calibration. I tried the following procedure:

"sit in car,
start engine,
have steering wheel in straight ahead position
without pausing, turn wheel slowly all the way to the left and pause at the end for a second or 2
without pausing, turn all the way to the right and pause at the end for a second or 2
repeat the last 2 steps and end in the straight ahead position.
turn off car, wait a minute, restart, and drive away for a few hundred feet.
you just calibrated your SZL ( steering wheel sensor to tell dsc if wheel is turned and to what degree)"

It did not work. Is anyone familiar with the "Trip Reset" menu? What the heck did i do? Is there any way to reverse this through the same menu?
