I had this issue on our old XC90 when the clock spring went and the number of cycles went over 300. After reading around and trying all of the above to no luck I found a post on sweedspeed where some had this issue and they got the software reloaded onto the module. With nothing to loose I approached our local Volvo dealer who was willing to try it at my risk. This worked and had no side effects.
it does seem that the modules can not record so many instances of an error before they permanently lock in to error mode. I will admit I did leave mine a long time as it started off only happening at full lock and only tried to sort it once it became permeant.
