Simple, water does not travel uphill!Looks like a good fix for water coming from above, well done.
The original design looks like a hungry scoop waiting for a load of Somethingwater, garden hose, high pressure car wash, bow wave when traversing water over road. Why on earth would they build that facing upwards 😟
Note to self, never direct water towards the grille of a Touareg.
Is that why they call them "ginger beers"?
