2005 boxster s - buzzing sound at 3k?

[woreilly]

I had mine in yesterday (30Sept05) out of frustration.

Of course, putting the mechanic in the car cured the noise for the moment, but he said they were aware of an issue and that there would be no engine swapping today.

I had the sense of B.S. when he said "Well, it's a sports car and some people take those noises as endearing." I told him it was endearing like a bad heat shield rattle on a honda. Then I heard about some alloy that is harder than others and that might be making the noise. My gut feeling is they know something but are on an advisory-only "put it off 'til later" response.

I was then told the positive note in bringing it in is that I am now on some "complaint list." It does not make me feel any better. This noise is really cramping my style and I'm about to boil over in frustration.

Could MrSparkle perhaps get the dealer (who did his swap) disclose the TSB? Then share with all of us here? At least we will have something to point to....

Thanks in advance!

If you want to be able to access all of the TSBs for your vehicle you can go to www.alldatadiy.com and get a membership for $25/year. I would look it up for you, but mine is a 2000 so I only have TSBs up to that MY.

AllData DIY is a fantastic tool and very cheap when compared with buying factory manuals and/or not having the information you sometimes need to get the dealer to do the right thing. Go to a dealer and say "according to TSB #.... titled ...." and you have his attention.

I'm on it like a fly on a pile of ....you know the rest.

I have not received my 987 yet, so I will make sure to get the TSB info.

Mrsparkle, what did you get as a loaner car? I hope you are driving the pi$$ out of that thing!

[mrsparkle]

Well, the loaner is not a porsche. I got a 02' accord which is fine. I love honda's but boy this thing is boring to drive.

I should be picking up my 987 today at lunch.

I finally got my car back after work yesterday.

Here's the info that I received:

The problem is with the design/construction of the crankcase. Under certain conditions, will rattle. It is nothing serious that will shorten engine life.

They would not disclose any more information or give me the TSB#. The service tech I spoke with informed me that he was not part of the initial conversation with Porsche. I was also told that I was "lucky". One party was for replacement and the other was against it. What a load of....

As far as the car, they neglected to fix the passenger window due to miscommunication and had to replace a leaking clutch master cylinder due to a loose pin. On top of that, they didn't bleed the clutch correctly so it feels like crap. The car feels different as well. I'm not sure if it's because of the clutch, but it does not feel "new" anymore. The engine is smooth and does not make any noises. Feels a bit slower. I'm sure I just need to break it in again.

As you can see, I'm not very happy about the situation. I feel that my car has lost it's "new" feel at 4700 miles. Does anyone know what my options are?

Hi All


Have a new 2005 boxster S with about 4500 miles on it. I have the 2200rpm rattle same as many of you. Can't say that I will live with this very long. Took it into the shop today after at least 4 other tries on this. Several months ago, took a tech out and he heard it. Went back another time and he did not work there anymore. Today, I took out another tech and he heard it. I told him about this website. If anyone has sucessfully fixed this problem, please let me know. This problem occurs when the engine is cold and is warming up into the 125 range. Then it starts passing through the 2200rpm range. After warming to normal temp, this problem is not heard. I hear it behind me somewhere. This is a awesome vehicle except for this. Any help is appreciated.

I saw some talk about this on Renn Tech. Possibly Toolpants can shed some light on this.

It might be linked to an oil relief value. And there is possibly a new TSB out from Porsche.

Has the flywheel been checked? The dual mass flywheel can get out of round somehow and cause the vibration between ~28K-32K rpm, mostly when the engine is coming down. It's something you may want to look into so the new crank is not being vibrated back to its' previous condition.

Btw, take it to a local Porsche only specialist and pay him an hour's labor to look everything over in the drive train to engine area. The dealers will wear you out with the "we don't feel anything" deal so you eventually give up. If you can take something in writing from a Porsche specialist with many years experience it will help them "feel the problem".

Update on my situation:

After attempts to have the car fixed, I told the dealer I wanted the rattles fixed or a letter on Porsche letterhead stating the rattles are a feature, not a flaw.

It took a week, but the 2050 rpm rattle seems to be fixed. They stated they replaced the oil piston. I put 300 miles on since I picked up the car (3 days ago) and have had no rattle at 2050 rpm.

On the issue of the 3K rpm, the one that sounds like a heat shield, supposedly there is a bullitin (or recall) of the washers holding on the exhaust.

Again, I have no rattles at 3K rpm after the dealer had the car for a week.

So in summary:

I am happy the car is not rattling. I am unhappy with the Porsche response.

If anyone wants more specific details, send me a PM.

I have a rattle in the dash that happens only when cold and only between 2600-2900 RPM. It's starting to drive me nuts. Last time it was at the dealer they could not replicate it- so they said it was "normal." After reading all of these posts, I'm worried that they might be correct- in so much as it occurs in far too Boxsters
