Water leak help or advice please

[Alfiedog]

Hi , I’ve owned my z4 2.3 m sport for 3 months no major issues always parked in garage and as we’ve had quite hot weather I’ve always had the AC on and never noticed anything wrong, however over the past few days a small puddle of clean clear water is sitting under the car on garage floor roughly around from back of engine possibly around bulk head region, it’s definitely not washer fluid or coolant as it’s crystal clear, could it be associated with ac ? Any thoughts on this please

That's your A/C condensate drainage.

As above.
The more humid the weather, the more condensate will be produced (it's just the way it is)!
