2.0T Burning Oil Smell

[yakev724]

After a 60 mile (somewhat spirited) drive yesterday I noticed a strong burning oil smell in the cabin, but figured it was a car in front of me (lasted only a few minutes then went away).

Earlier today after parking the car I smelled oil again so I popped the hood and inspected the engine. Didn't see any leaks around the various seals but saw some spray on the EM and cat, but hard to tell whether its anything new or if its been there for a while.

2011 2.0T with 67k miles (pistons/rings replaced at ~53k). Regular maintenance/oil changes, no other issues whatsoever. Car's CPO so planning to take it to Audi on Tuesday, wanted to see if anyone has any other tips on what to check. Searched and only found instances of crankcase seals blowing and being replaced.

Could you please point out where this sensor is on a photo of the engine bay? I haven't been able to find anything obvious. Had the smell happen again today (3rd time), took another photo of the EM but doesn't appear that there's any new spray on it, so I guess its coming from somewhere else...
