The breather hoses get very brittle due to age and repeated heat cycles. I have no idea what the long hose is, looks as though it could be for the near side headlight washer.Arnie_one said:

Mr Tidy said:Just a thought but when I got my current Z4 the leak was from one of the headlight washers. It emptied the reservoir overnight, but because it was dry I could see the puddle next morning!
I had all kinds of leak problems that caused mold and damaged wires. Got the car 2 months ago but car is from 2008. I have it now on the table and resealed lens.
