Original Owner, 167K, B7 S4 MT6 Avant - driving from home to Audi Dealer, for A/C Inspection/Service - one (1) city block way - Boom, Red, Oil Can and Oil Pressure Low - lights the dash! 3K mi. into 5K mi. Oil/Filter interval, oil level, normal where I keep it, car had been setting for ten (10) days - normal, also.
Two (2) weeks earlier - did a Full OBD 2, with quality scan tool from Foxwell/ECS - zero codes, all aspects.

Light stayed on for maybe ten (10) seconds - I headed back to home - went out, five (5) seconds later, came back on for five (5) seconds - went out. No leaking...

I drove on - Seventeen (17) miles to dealer - stayed off. Dealer Tech, found - no codes. Their opinion - the factory, original Oil Pressure Sensor - was in process of Failing, (to always ON !

A thorough engine compartment examination - no signs to oil leaks at sensor or even in that area.

R/R, seems, fairly straight forward, just akward to get to... And some, hoses to be moved out of the way...

Please, advise - Sensor - now a Problem Child, to be replaced ?
