Hi brains trust. I recently had an issue with my 2008 R50 where the washer bottle wouldn't hold water after the car came back from service. A few refills later and I noticed the sound of rushing water when I hit the brakes. Back to the dealer and they removed the drain plugs in the left hand side door sill and drained the sill. Suddenly the washer bottle leak was also fixed. My question is what is the rout the hose from the bottle takes to get to the washer nozzle on the rear window? It seems logical to me that they didn't reconnect the hose and somehow it filled the door sill, is this possible?
