After a recent white-knuckle encounter, swerving radically to avoid hitting/killing a bunny at 55mph - triggered my flat tire and DSC warning lights in which I could not clear the codes. A scan of my steering angle showed that the sensor was stuck at -1440°. My attempts at performing the simple steering wheel clock left then right to reset/re-adjust the sensor failed miserably.

I've come across this "seemingly unfixable" Steering Angle -1440° and 1440° fault issue in the past. After a few unsuccessful and frustrating attempts to resolve with INPA and my Foxwell; I decided to try this:

1. In the driver's side footwell fuse panel - Pull fuse #F2 (It is the second fuse from the top first row labeled with the DCS traction control symbol *marked on the inside cover of the fuse panel cover).
2. By doing so; this will cause the flat tire and DCS lights on the clock to go out momentarily each time you start the car. BUT the warning lights will immediately illuminate and stay on as the computer senses that the fuse is missing (?).
3. Drive the car as usual (ignore the lights on the dash), for 25 - 50 miles or so cycling the car on and off before each drive. Making normal turns as usual during your daily routine.
4. Replace the #F2 fuse.
5. Connect your OBD II reader and perform a routine scan.
6. The scan should come up with a new fault in addition to the DSC and steering angle fault codes.
7. NOW you should be able to clear all fault codes related to the DCS and steering angle faults.

Now that the -1440° faults have resolved/ been erased and the warning lights extinguished on the clock/speedometer - At this point; if it hasn't worked, you can then proceed to moving on to try pulling, cleaning and resetting the steering angle sensor.
With any luck you may avoid having to replace the sensor and dealer.

I should note:
I continue to have a faulty steering angle sensor but managed to reset/recalibrate it with my Foxwell NT 510 OBD II scan tool. Although the issue occasionally remains as a fault during routine scans, the flat tire & DCS warning lights cycle on and go off (as normal) after each start up and remain off while driving. (Yup. I'm essentially ignoring an $800+ replacement + dealer recoding).

 

Standard Ignition 6 Terminal Steering Angle Sensor - SWS91

Part #: SWS91Fits Mini Cooper
Steering Angle Sensor
$342.99 Each. This BMW steering angle sensor I purchased directly from O’Reilly Autoparts says right on it when pulled right out of the box . After installing the SAS , I had it programmed at Mini Corsa in Burbank, Ca. and eliminated all the dash lights trifecta , which is nowhere near your stealership rates .

 

Yup.
Well I'm $$broke$$ right now.
As much as I'd like (to have a new SAS) - I'm OK with having me (seemingly) successful at re-calibrating the SAS and having no lights on the dash.

That doesn't mean or make right. But...
