Anybody experienced steering angle sensor failing twice?

[bmw540san]

Po had it replaced at the dealer in 2010 with 60k on clock.

Now at 106K I'm getting random well know trifecta of lights ( ABS / BRAKE / DSC) which quickly goes away after doing the re-calibration with full left and right steering wheel movement cycle.

No codes found with my AutoEnginuity which is way superior to generic scan tool and it does have enhanced mode to deal with Airbag and ABS codes.

I can get the new genuine BMW sensor for $130 shipped (really good price) but I'd hate to replace good sensor.

I did all the other usual checking: voltage issues, speed sensors etc...

Having 2 older E39's with ASC that don't have this sensor and considering I've had the X5 for 2 years now, I'm not really experienced much with DSC and steering angle sensor.

Any thoughts?

Thanks.
