They are a friction fit and are known to fall out. Check the socket they fit in. I can pretty much guarantee that the socket has a crack or slight split allowing the nozzle to pop in and pop out easily. I lost all 4. Here in the Great White North the temperature fluctuations cause the plastic to shrink and expand making the sockets loosen. The sockets and balls are not available as separate items and indeed the whole nozzle assembly needs to replaced at an exorbitant price.
I removed the fuse controlling them and capped off the sockets with simple plugs since I never use them anyway. One day when I have $500.00 I don't know what to do with I will buy new ones and replace them. After 2004 Porsche went with a much better more robust design.
