Always get a patch near the rear passenger side wheel when parked up. I assumed was just water draining. Clear, cold, no smell, not oily consistency.

This was until the car has been elsewhere, and the patch on the drive still hasn't disappeared in the sunshine after days. What could possibly be leaking in that area?? You can see on the picture where the marks haven't disappeared after a few days when parked in a slightly different spot on the drive.

My first Ateca - a 1.0 petrol - used to drip condensation from a hole near the joint of the flange of the rear back box of the exhaust. The drain hole (about 4mm dia.) was a design feature for this purpose.
I've not noticed this on my current Ateca - a 1.5 petrol - and I've not looked underneath to see if there is a drain hole.
This has been raised before, if you search " exhaust leak" or "exhaust condensation drip" there's a few posts on this topic going back to 2017.
