Customer Question
I HAVE A PO455...

I HAVE A PO455 CODE EVAPORATIVE EMMISION SYSTEM LEAK. IT STARTED WITH A GAS CAP CODE. I CHAGED THE CAP BUT THE LEAK CODE REMAINS. ANY SUGGESTIONS??

Mechanic's Assistant: Has the vehicle turned into a gas hog? And how does it start -- same as usual?

GAS CONSUMPTIONS SEEMS THE SAME AND STARTING IS NO PROBLEM.

Mechanic's Assistant: What is the model/year of your Porsche?

2011 PANAMERA V-6

Mechanic's Assistant: Are you fixing your Panamera yourself? What have you tried so far?

I HAVE BEEN DOING SOME SIMPLE FIXES BUT ALL I TRIED ON THIS ONE IS I BOUGHT A NEW GAS CAP

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

THAT SEEMS TO BE THE ONLY ISSUE AT THIS MOMENT

The only accurate way to locate a leak in the EVAP system is with a smoke machine. Many of these leaks are smaller than a pin head and you'll never see it by eye.

Please understand that I don't know your skill level or tools
you have to assist us. Also understand that I can't see, smell,
hear, or touch the vehicle either, so your patience is
appreciated. JA is a great Q/A site, but it does not replace a
repair shop. So please don’t shoot the messenger if I have to
deliver bad news:)
If you are satisfied with my answer, I would greatly
appreciate a 5 star rating now before you leave the site and I
will still assist you after you have rated me too if another
question pops up. I don’t get credit for helping you until
you rate me

Thanks, Ron

Thanks again and please remember to rate me 5 stars now
and keep this link in case you need me again later on.
I don’t get credit for assisting you until you rate me
My goal is to assist you in the repair of your vehicle by
supplying you with well educated information. I may not
always have the exact fix you wanted to hear, but my job is
to get you on the right track, which I always do. I can’t hear,
see, smell or touch your vehicle from where I’m at, so your
understanding of that is greatly appreciated. There are no
magical answers, but I do my best to guide you in the right
direction.

Ron
