I was under my 2010 Cayman base PDK and spotted this missing bolt, passenger side - any ideas what the black tube is, and what bolt I need? Seems like there was a washer too…

If I had to guess from this one picture that 'black tube' is 9A1 106 625 01 Water pipe Return line, and the missing fastener is 900 385 009 01 Torx screw M6 X 16. There is no washer.

You bigger issue might be that oil leak though.

This was all found from the parts diagrams that you can free download from Porsche here.
