The rear switch's OUT line goes to the EGR flap and the VAC line goes toward the vacuum pump and intake flap switch among other things.
Would anyone else care to check these lines and/or the behavior of the intake flaps? |
My setup is like yours, with the rear switch vacuum line going to the resonance flap switch. Just another guess, but is it possible that the electrical connecting plugs to each unit could be switched? I don't know if a code would be generated, but if that were the case, the vacuum switches would be sending the ccu incorrect information.
