My check engine light is on my 06 9-5 2.3t and I know its the charge air bypass system. My question is what do I need to do to fix this problem? all my hoses seem fine. Also does my wategate have a bobbypin style retaining clip or Circlip? And ive replaced my turbo bypass valve with a stainless steel one with a stainless diaphragm. So thats not the issue. Like I said all the hoses are fine, I heard that there are 2 other valves in the CAB system that may be responsible for the P1110 code. I need the proper name of said valves and where they are located and about how much they would cost.
