John, thanks for all advice...   Like you suggested, I am planning to  
replace the sensor, o-ring, and clip all at the same time.     Will  
grab a few extra clips just to be safe.

Where did you end up ordering your parts?   Dealer or something like  

Im not too shocked about the sensor going bad after 44k miles.  I  
really don't drive my S4 as often as i would like.  I am frequently  
traveling abroad for months at a time, and when I am actually back we  
try to put as many miles on my wife's Z4 to maximize the milage on her  
lease before it expires next year.    I think the S4 is just symptoms  
of the lack of TLC she usually gets when i am around.

Speaking of neglect,  the other project that i have been  
procrastinating is the replacement of my leaking washer pump.   
Supposedly they are notorious for cracking, and a pain in the A** to
