Hey my friend I've been reading up on you I have the similar problem with mine with the 4055 code I have a Panamera 2010 I changed the purge valve solenoil canister and it still giving me the check engine I'm following your footsteps you said something you going to check the rear to find out something there how did you solve your problem besides you that hose to your vacuum pump was anything wrong from the rear( leak detention pump) I don't want to go into taking off the intake manifold just hoping it's not that area,!?? thank you for giving me some of your knowledge that what you worked on I'm also going to check that hose you said like you said pass it on to the next guy can you reach out to me and tell me what did you find out to solve your problem thank you brother
This was the purge valve canister solenoid that I change it was had tape on it I figured that was the problem but I still bring up that 4055 code I'm hoping that it's something in the rear of the gas tank I smell some kind of fumes inside the cabin every time I put gas more than a half tank I get that check engine light back on
