Just changed the headlight bulbs on my V6, jees they dont give you much room on the near side!!!
However, whilst struggling near the battery I noticed a bit of pipe sticking up. It is about 100mm long, 10mm in diameter, comes out of a larger 16mm(ish), pipe with a capped and threaded end to it. Any ideas what it is and should it be connected to anything, looks like it should???
