Oil leak in right rear storage compartment? Source? (2005 Cayenne)

[Some05Cayenne]

I'm complexly stumped.

 

I noticed a dinner plate sized oil patch under the right rear corner of the car, and I have no idea where it’s coming from! I can’t see any hoses or piping that could be the source of the leak. It doesn’t look like its coming from the brake system or the rear differential.

 

Today, I opened the right rear storage compartment and noticed small amount oil in the bottom of that compartment, but can’t find any source of the leak!? I’ve done a search of previous threads and can’t find any similar cases.

 

The only additional info that I can think that might be relevant is that lately I have heard some clicking noises coming from the left rear after I started up the car but it went away after a few minutes. It sounded like a clicking pump. This is while the car was stopped.  Also the rear glass support pistons have gone bad but I’m seeing no oil in the ceiling.

 

The oil seems to be yellow in color. I’ve checked the fluids under the hood and everything is full/ nothing matched the color of the oil.

Any and all ideas are much appreciated! Anyone know of a step by step tutorial on how to remove the interior panels so I can take a better look? Please help me out, I’m just starting to learn on how to maintain and work on this car.

Does the AC still work? Freon gas has oil in it and there would be a run to the back condenser.

AC seems to be working fine at the moment.

Looks like new engine oil. I bet someone put their top up oil 1litre bottle in there and it leaked! I had a film of oil in my spare wheel well and some dirt, cleaned it out when I bought the car but no idea what component could put engine oil there.

If cleaned up does it return? If so sell the car quick it must possessed and dripping super natural liquids. 

 

 

 

I can't think of any other possibility and as sherlock says "if you have eliminated the possible then only the improbably remains which must be the truth"

That's a good suggestion as well. That's where I put my top up oil. How about hydraulic fluid from the power lift gate?
