Tapping Noise Bottom of A Pillar 2005 997 Coupe

[afishkind]

I have developed a tapping noise in my 2005 997 Coupe where the passenger side A Pillar joins the dash nearby to the windshield.

I have done the following:

1. Removed glove compartment and felted everywhere.
2. Removed speaker covers, defrost vent plastic, and A Pillar trim - cannot isolate the noise.
3. In the right front wheel well ... removed trim and taped up any moving parts with sticky AC tape.
4. Made sure the ventilations ducts are solidly connected.
5. Removed any possible offending plastic/rubber from the frunk.
6. Gummi Pflegged all seals in the region.
7. Used Pedro Wax underneath the window seals.
8. Took the car to a Porsche window specialist who said the noise was not due to the windshield and he would even reseat the front windshield he was so sure.


I put the phone down in the region of the tapping sound and recorded the following audio:

The picture in the audio shows the area of the noise ... and where the phone was lying face down recording the audio.

Yes ... I should just turn up the radio or enjoy the AWE exhaust ... but the noise is killing me. Predominantly makes the noise when going over bumpy road. Local suspension expert says it's not the front right suspension.

Thanks for any help ... I've tried everything mentioned in the forums and no dice. Thanks in advance for any advice.

Car isn't stationary ... it's just a single picture running the length of the audio ... I should have realized that could be misinterpreted ... I am in fact driving. AC was on at the time I recorded the audio ... but noise is present when AC is not on.

Better response if you posted this in the 996/997 forum. Most of the denizens here don't have much experience with the water cooled cars.
