How to bleed LPG system (330CI Prins system)

Postby mhanna2002 » Wed Feb 02, 2011 12:09 am

Hi all, as this is my first post I was wondering if I could have some guidance. I have recently started to smell gas while driving my 330ci. I lifted the bonnet to be greeted by a smell of gas. I think it is most likely a loose pipe. As such I was planning to loosen the clips force the pipes on further and retighten as to see if this remedies the problem.
My question is, do I have to bleed the system once I have refastened the hoses securely? Or does it automatically bleed its self?
I’m sure this is a fairly stupid question but I wanted to confirm before I started disconnecting hoses

No bleeding of gas system needed. But try to get some leak detector spray and use that. If unsure, take it to an authorised place.
