Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

So, I'm still having this "blowing on the top of a coke bottle" sound coming from the front of my car.

POST 1 / ORIGINAL POSTEROriginal post

So, I'm still having this "blowing on the top of a coke bottle" sound coming from the front of my car. I've narrowed it down to either the fuel tank vent valve or the fuel vent line valve. I took a look at the tank vent valve and that little thing is packed in next to the top of the fuel pump (top of the tank) and the other one is somewhere behind the gas cap. Has anyone on here attempted to replace either of these? this sound is driving me nuts..

POST 2Original post

My tech is replacing the fuel tank vent valve today but this valve is on the intake manifold near the alternator not near the fuel tank. I don't have the symptoms that you are. Trying to solve a running problems.

Is the front trunk lid leading edge *below* the front bumper cover, and evenly below the front bumper cover all the way across? Sincerely, Macster.

From the earlier description this is not related to the hood level as it is sensitive to throttle position. That is, as soon as the throttle position is changed, even slightly, the noise goes away. The fix on my Boxster many years ago was to replace the vent valve and at that time the p/n replaced was 996.201.231.01.

Thanks. I had thought the front trunk lid issue had been eliminated in an earlier thread but didn't do a search to confirm this. Sincerely, Macster.

Did you ever figure out what the fix was? I think I am having the same problem with my 996TT.

POST 8Original post

Call me crazy but is it possible that one of the air scoops has picked something up causing the hooting sound? Hey it takes nothing to have a feel inside. There might be a dead rat in there and the intake air is blowing across its *** hole hehe.
