Audi A6 passenger footwell full of water???

As a new owner of a resale A6, very unhappy to find footwell full of rain water. Seems speaking with local dealers and garages, that this is a historical problem with Audi/VW.

Battery compartment under main wipers has an outlet with a rubber/plastic pipe where debris can collect and block. Simple to fix but not to be seen in any literature and or websites.

Result is a huge amount of water fills your passenger side from behind the glove compartment.

Please contact me if this has happened to you, Audi refuse to accept this is a problem or even warn people about it potentially happening to them.

Lets see if the mighty Watchdog can help?

Many thanks
