Steering Angle Sensor Fail on E39

A few months ago the DSC light came on in my Beast after I changed the battery. I made a post about that, but it no one else had seen this. I didn't worry about it at the time because nothing else seemed to be wrong and being the middle of the summer, it wasn't that big of a deal. I finally took it to my independent mechanic yesterday who said the code came back as "DSC-104 (255X) Steering Angle Sensor, Internal Fault."

I've done some searches and as much of a problem as this is on the E60 it must be pretty rare on the E39 because I haven't found many posts about it.

According to the book, this is a .8 hr job, but my mechanic thinks he's going to have to pull the steering wheel column to get to the sensor so he can't understand why this is only .8. On the 3 series it is listed as a 4 hour job and on a 5 series it is 5 hours.

There are no dead spots in the steering wheel so I'm questioning whether there is anything wrong with this sensor.

Has anyone else had this problem or had to have this sensor replaced? If so, how long did it take and were your symptoms like mine (ie just the DSC turned off)?

Never heard of that particular component failure, but if it is bad it's important to repair for DCS to be functional.
