Here are two screenshots in DIS v43. Notice the different options depending on which module/section you go. I don't know if these screenshots will help.

In SSS are there similar screens? Which option are you selecting when you get the 90 degree wipe fault?

I don't have an X to connect to further look into what these options do. Also, I'm about to ship it out so I won't have access to the GT1.

The screens you showed me i did that in dis wheni was using it i got that error in dis when you do a quick test it poped in LWS(steering angle sensor). I did a test plan followed the procedures come up nothing, in SSS it just connects to modules in the car and so i click on LWS and then it comes up with 2 options replacement and encode i tried both of those none of them did anything. The light is still up but i remember a year or two ago when i called up a guy to diagnose my car he turned the light off but then when i drove it the light come back after like a half a mile.

I assume you still have the DSC/Xdrive fault on your dash.

It seems to me since you're having problems calibrating/connecting to the steering angle sensor that is probably the culprit.

Let us know if there are any changes to your situation.
