1st Gen R53 Cooper S Fluid leak inside driver wheel

As you can see in the pic, I have a fluid leak just I side of the driver wheel. I Park with the tire on the yellow mat. Fluid is viscous like PS fluid, but not quite colorless and not much smell. I looked under the car and didn't see anything obvious. The PS fluid is in the normal range in the reservoir.

I did look at the PS hoses and there is a leak on the front hose, but it doesn't look like it could cause that puddle. I have appt booked but not until 12/1. Any ideas?

Thx
