Default A new invention

Why isn’t there a system that collects rain water and feeds it into the window wash bottle?

The collection point could be at the foot of the windscreen or under the bonnet shut on the wing somewhere, it could have a plastic mesh filter on it and feed a wideish bore tube straight into the bottle.

I was sat in hammering rain yesterday for at least 3 hours, what a waste!

Anyway when it has made me millions I will remember you all with fondness.

Please accept this thread as evidence of ownership of the IP LOL!

probably because it doesn't rain washer fluid pre-mixed to the right solution, but surely its not beyond audi to have designed a "pre-bottle feed" reservoir to house neat undiluted washer fluid to feed into your new (patent pending) device!

I always wondered about this, but I suspect it's because the water coming off the windscreen would not always be clean, like rainwater.

Now, if we could only build a filtration unit that could thoroughly clean the water, combined with the pre-mix dilemma of getting the correct ratio of washer fluid, and this time next year we could be..... skint!

or if you are driving a D3 then half of it will leak out one of the many points that seem to leak regularly lol

Maybe the collection point could be in the passenger footwell, the carpet would be utilised as the filter!
