I have an unusual buzzing noise coming from the instrument cluster area on my 2000 Carrera 4 with white dials. I know there is a TSB from Porsche but it seems like it is for the 997's. I can not tell if it is air related or from an electronic buzzer.

The buzzing noise occurs at about 75MPH and above. It is inconsistent, sometimes it will start at 75MPH and other times at 83 or 85 MPH. Based on the inconsistency and the sound, I am thinking it could be wind related, but how is wind making its way to the cluster? It sounds just like an electronic buzzer and I noticed something that looks like a buzzer on the back of the instrument cluster when I changed some bulbs a month ago. Could this be a speed related alarm?

It is very annoying and I don't know where to start; I appreciate any advice.

If this does not sound familiar to anyone, perhaps I can try and create a video of the problem and post it.

Maybe the speed alarm?

Or maybe your wing is not working right.

Thank you for the reply. I tested the wing and it is working properly. I set the speed alarm and it is a completely different sound.

This is a high-pitched wind noise that sounds like a kettle boiling water!

I have created a video while driving to show the sound and how it changes with speed. There is no consistency in the actual MPH, I think it is just the wind resistance.

Also, it seems like it is coming from the instrument cluster, but it could be somewhere nearby from the driver's side window area.

Try covering the windshield trim (outside) with masking or duct tape. Cover the windshield to trim joint around the driver side, so that the wind can't get under it, and go for a ride. If it is the trim vibrating this should change/quiet it until the tape gives up.

Thank you again for the suggestions to try, but still no luck. The windshield was replaced by the previous owner and I checked the trim which is glued down very well. I tried taking it for a drive with the top down and used my hand to feel the windshield trim. The trim did not move, but it still made the same sound. I'm wondering if it could have something to do with the front vent in front of the wipers.

Also, I am missing most the undercarriage panels including the front left and right that sits close to the bumper. Could this be allowing air into the driver's side cabin area?

I appreciate the suggestions; I am totally lost where to continue.

Have you tried loosening the cluster and putting a towel between it and the dash - while carefully driving the car?

That might help to isolate where the noise is coming from.

Usually it is a flawed applied sealant between the windshield and the groove along the bottom side,about in the middle of the windshield, not between the trim and the windshield. There is no infiltration of rainwater, just only air noise.

Thanks to everyone's help, I have finally been able to resolve this annoying problem!! :D

fpb111 (Post #4) was exactly right with the TSB he posted. It was actually coming from the windshield trim on the driver's side. I only tested the inner trim that faces the windshield before. The noise was coming from the outer trim that faces the painted surface of the A-pillar.

I was able to locate the exact location by using a compressed air hose and blowing it along the trim until I recognized the noise. I sealed it with a generic black sealing putty. No more noise!!

      996 Cluster Won't Acknowledge Instruments
      By Michael hurta
      Hi - 2002 996: Scoured the lists but can't find this particular cluster problem anywhere.  In short, my salvage cluster shows a list of errors on start up but my original was fine....  Here's the details.  My current cluster shows an intermittent airbag failure warning on the led screen followed by the idiot light.  It usually occurs at start up, clears at the stalk and the idiot light remains on, but flickers on occasion.  My mechanic had ruled out everything he could related to the airbag warnings and since he didn't have a spare cluster, couldn't swap to test for that. I personally purchased a salvage cluster, removed the battery terminals, installed it and it came to life (I'm also having to buy replacement connector housings because mine disintegrated).  The problem is the info screen pretty much scrolled through a variety of issues like oil pressure feedback, temp feedback, fuel feedback, etc.  The oil pressure gage was also unresponsive.  I expected the odometer to be wrong, but didn't expect all the errors.  I also started the car and while it ran, it did run rough, sputtered a bit.  Do I have a bad salvaged cluster?  Does the cluster need to be programmed (beside the odometer)?

      Whistling Noise 2003 Boxter 2.7 Tiptronic
      By David MB
      Help - i have a 2003 Boxter tiptronic s - in great shape other than a shrill loud noise like a Kazoo that only happens above 78mph - it sounds as iff coming from around the mirror area of the windscreen but then occasional sounds like its coming from the speaker area passenger side - that being said could be sound transference. Read a number of blogs about badly fitting windscreen so put tape over top rubber seal and body but still there - - as a say like a kazoo at 78mph with hard or soft top - absolutely driving me mad - any help gratefully received.

      Newb with a top problem
      By Toyguy
      I just bought myself my first Porsche, a 1998 Boxster.  I have an issue with the soft top that I'd like to get some guidance on.
       
      The top goes down smoothly with no issues.  It also comes up smoothly until it is nearly all the way up.  Just before the dashboard Top light goes out, there is a pretty sharp metallic twang or snap.  It did this when I was looking at the car before purchase, and it did it again this evening when I put the top up after driving the car home.  I'm assuming it's getting caught on something but I wonder if anyone might have suggestions on what to look at given the late point in the cycle where it occurs?
       
      Thanks!

      986 boxster grinding, shredding metallic sound
      By Astarael
      Hello there, this is my first post here and I’m writing because of problem with my boxster.
      Today in the morning I’ve started my 2002 boxster and noticed strange sounds from the engine/ rear side of the car
      It’s a metallic, grinding sound like a loose piece of metal or something like that
      Sound disappears when you press gas and comes back once you loose the pedal, I don’t know if it changes while engine is warm
       
      Also, check engine light shown up yesterday, when I connected my BT OBD2 there was no error code.
      I came with that to workshop also, and they said it’s a catalyst efficiency error.
       
      I’ve had that error code a while ago, I’ve replaced mass air flow meter and check engine light disappeared. 
      I think it might be a problem with maf again because I bought not the cheaper, not the original one, but why are there these strange sounds? I’m worried about this. Could it be catalyst this time? Or again should I replace maf? This time I’ll buy original one.
       
       
       
      here are two Videos I made
       
       
       
       
       
      Also I’m sorry if you can’t understand something, my english is not perfect.
      Thank you for all replies, I hope we will solve that problem together

      Is there a way to know if a used front differential is good?
      By neoplanet
      Hi.  The title is probably self explanatory.  If I get a used diff, is it just plain risky, or can it be understood whether the thing is one of the good ones or not before I replace my noisy one with it?
       
      Much thanks for any insight.
