bummer on your codes/lights
Its been a while since my issue but I do seem to recall having a few codes in there for Steering Angle Sensor (SAS) and Yawl both. However I did also have my batt disconnected for a while so which causes the SAS to need resetting which in theory can be done by turning wheels lock to lock. However I do recall lots of posting about not being able to reset SAS with the lock to lock trick or postings about people thinking SAS were bad yet able to fix by going through GT1 calibration of SAS. I would suggest trying that before replacing.

I do recall being able to get rid of my SAS error before replacing the Yawl sensor however my yawl was intermittent.

Some of my earlier posts at start of thread also show how in GT1 you can show the outputs from the SAS and Yawl sensor. If I had to do it over again I would start by checking the values being reported by SAS and Yawl (my Yawl was missing one axis) , re calibrate the SAS via GT1, then maybe move to replacement parts.

I bet you have already but just for good measure on the anything electrical with the X, have you confirmed your battery is in excellent shape?
