My GL is leaking something. Any ideas? Pics attached.

I just bought this 2013 GL350. Noticed these spots in my driveway. At first, I thought it was the air conditioning condensation. But it's leaving these oil like marks on my (wet) driveway. When I touch the spots, I don't feel any slimy residue, can't see any color, and it really doesn't smell. A neighbor thought it had something to with the recent degreasing of the engine and the air conditioning condensation, but I'm not so sure. Any ideas?

Might be diesel fuel. Check the connections at the fuel filter.

I think you're right. I parked the car in the garage last night for the first time and this morning the whole garage smells like diesel fuel. I expected a little diesel smell anyway without a leak, but this is pretty strong. I'm going to tear into it today or tomorrow.
