How to test Intake Resonance Flap ?

Recommended Posts

Is there a "shadetree" method to determining if the resonance flap on the 996 intake is opening at the correct RPM?

I can test the solenoid that triggers the vacuum but I want to know if the flap is actually opening @ the correct RPM.

      Hello, I have 2004 cayenne s that I’ve been tracing down leaks in. I noticed that on the air intake tube near the air filter, there is a round metal clip that attaches two separate tubes together. Not the hose clamp style, but a spring clip that just pops on. I can’t find any info on buying these anywhere. Does anyone know the part number for these? Thanks.

      Cabriolet side/mud flaps are actuated by this lead screw which is attached to the shaft of the drive motor.
      If your tops gets out of synch as mine did when the bolt that holds a side arm casting to the hydraulic piston fell out, then it creates a cascading nightmare of fragile part failures.
      First that spindly potentiometer arm with the lightening holes to save a hundredth of gram of plastic breaks off, now these. 
       
      This tiny molded soft plastic nut runs on what I measure as a M8 x 1.5 pitch lead screw, which is apparently less common than the M8 x 2 pitch lead screw used in 3D printers.
      It is ridiculous to replace the entire side flap assembly because this soft plastic lead screw nut gets run to the end and stripped/cracked so it runs too slow and the computer times out.
       
      Has anyone sourced this lead screw nut or a replacement M8 x 1.5 pitch lead screw nut with a triangular or round flange that could be cut down square to insert into the carrier that operates the flap?

      I'm getting a weird buzzing noise (buzz/whine) when above 4000 RPM. It's a 997S 1st gen no mods, with about 70k on it. It sounds a bit like the car is struggling at anything past 4000 RPM.. It happens in gear and in neutral. When its hot and cold. if anyone has any ideas of parts I should look at, that may be causing this, please let me know!
       
      I'll post a video of the sound in the next couple of days too, so you can hear what it sounds like.
       
      Thanks a lot!

      Hello all,
      I have been lurking around here for almost 2 years.
      I have a 2006 Cayenne S with automatic transmission with about 70,000 miles. This morning I went to drive it to the car wash. When I went to accelerate onto the autobahn the engine acted as if it were in limp mode. There was no power under load above 3,500 RPM. In neutral the engine will not rev past 4200 RPM.
      Here is what it is not doing or has been replaced
      - It starts and idles fine.
      - plugs and coils replaced last year less than 10 thousand miles ago.
      - I do not have a check engine light on.
      I am thinking:
      1. MAF sensors (looks like a special tool required for replacement).
      2. Throttle position sensor
      3. Fuel Filters
      4. Fuel Pumps
      5. Or another sensor related to fuel pressure or fuel regulation/delivery system.
      Does anyone have any trouble shooting tips or advice before I give up and take it to the dealer?
