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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi Crawling over my Boxster, I have spotted a broken piece on the forward-most throttle body tube. It looks as though a plastic "button" is missing from the top. The part has the code 5.02704.0 but seems to correspond to "99611013002 Intake manifold air tube with vacuum unit. Porsche 986 Boxster / 987 Boxster" on a parts diagram. I would appreciate your thoughts on whether this is a problem and if there are any diagnotic tests I should try. Thanks Russ

POST 2Original post

Has your car thrown any codes? Upon examination do you recognize any parts absent a vacuum connection? Maybe a broken off plastic line that WAS connected to the tube? As a vacuum associated part... if you're not having any problems... I wouldn't worry about it. A parts diagram would reveal what is the part number for whatever is meant to be plugged into that port. A wiser mind will chime in shortly. Good luck.

POST 3Original post

Where is the location of the vacuum operated pneumatic valve that opens the resonance flap on the intake plennum? Doesn't that valve goes on top of the white plastic shaft on the plennum? Cannot remember clearly..

POST 4 / ORIGINAL POSTEROriginal post

Thanks guys Looking at the parts diagram this moulding does not take a pipe or tube. It looks to hold the top of the axle of the resonance tube flap. That said, it looks like a press to test fixture. I was not sure if it should be gas-tight with a gasket or some-such.

Is that what this is for? https://lnengineering.com/porsche-99611012053-resonance-tube-vacuum-leak-repair-kit.html

Brilliant - thanks. Very helpful. I will start by trying to see if there is a leak there.
