Denna video visar hur du löser detta problem med felkod P0172. Oftast är det en vakuum slang som orsakar problemet.
Had a P0172 Bank 1 System too Rich code on the Volvo 850. Going to show you the vacuum hose that is causing the problem. There dont seem to be to many pictures or videos out there on this. A common problem with the 850 and other models is a vacuum hose connected to the intake manifold underneath the power steering pump. I will show you where it is and it should be the first thing you look for. Enjoy!
