2005 boxster s - buzzing sound at 3k?

Mrsparkle:

I feel bad for you and your situation. You deserve much-much better.

I think you need to start making phone calls and writting letters. Start with the owner/GM of the Porsche dealer that you purchased from. Also call the 1-800-Porsche phone, and log a complaint with the proper people within Porsche of North America.

Also, very importantly, set-up a meeting with some high level person at your dealership (Service Manager and/or GM) along with the Porsche Regional/Zone Service Executive. All zones and regions have them. The dealer can find out when he/she is going to be at the dealership next.

Hope this helps.

Was this a type of buzzing or vibration that was located between the seats--like on the centerline of the car?

I drove a 987S a month or so ago and when driving it cold--the car only had 3 miles on it when we drove it--and giving it a little throttle (from say 1/4-1/2) the car would vibrate when I hit 3000 rpm right between the seats.

I had driven 2 other 987's and they didn't have any vibration. I have to say, had I been serious about the car (we were only trying to compare the 5 spd to the 6 spd) I'd have run from the car--it was really disconcerting.

Utter dispair. Not only is the car still rattling at 3K rpm, it is now making noise at 2100-2200 rpm.

I found the perfect place to replicate the issue. I have a mile long hill near me, fairly steep grade for Wisconsin. The noise comes about when at about 25% throttle--the uphill allows me to stay on the throttle but not gain speed. More than 25% and the noise is still there but not the resonance. Gear selection seems to show the noise more often in lower gear.

I went up and down the hill trying to convince myself the 2100 rpm rattle was somehow different and it is different. It is not nearly as loud, not nearly the resonance the 3K rpm rattle has, but it's most definitely there.

Even my wife hears it--and that's saying something.

I'm going to try to record it. For MikenOH, it is in the centerline of the car (but also hearing it out the vents), close (or below) and behind where your elbow sits on the midline arm rest. The noise could be mistaken for a sick valve train until the resonance sets in and dominates the exhaust note. It sounds like a heat shield vibrating or (perhaps better) a metal room fan that is out of balance and beginning to resonate when you turn it on high. It happens more consistant when cold, but on my hill (Hwy TT in Waukesha, WI, 1 mile south of I-94) it happens when warm, too.

I'm going to call Porsche on Monday. I don't know what to say. This is a *frustration* that will require action and not words. Mrsparkle: would you please detail more precisely what your mechanic was saying about the issue, or was that really all that was said?

just to make things clear on my post, i definately do not have the same problem as the others, mine make a funny chattering noise for 3 seconds during warmup, while driving, and the noise comes from the front of the car. it sounds like a cicada bug in the summer... again it's not from the engine, i'm not worried about it at all.

Unfortunately, I do not have any additional information.

Hopefully, I will be able to talk to the someone when they fix my window regulator. I have no problem with replacing parts in 2-3 years. I was hoping to be service free for the first 20k or 2 years. My main concern is with only 4700 miles, I already needed a new motor, clutch master cylinder and window regulator. Come to think of it, I need to have my headlights checked as well. They make a grinding noise everytime they auto level with the engine turned off.

I thought about trading up for a cayman but it shares too many parts with the boxster. What to do....

There is a thread in the UK Boxa forum that the 2100 rattle is a defective oil valve and SOME dealers there are starting to take care of it.

I took it to the dealer. It had a metallic rattle around 2,100-2,200 RPM between 125 and 175 degrees.

Since it only does it in this small temperature range, the techs could only try and locate it a few minutes at a time before letting the engine cool down again. After 3 days, they thought it was the oil pump, so replaced that.

Picked it up yesterday, and 4 rides from cold later, the noise is still gone. Keeping my fingers crossed!

My 06 Finland made 987S made this buzz this weekend, while cold. I'll have to isolate rpms and conditions and let you guys know. Car has 250 miles.

Sounds like a heat shield to me.

Chris C Atlanta, everytime I see this thread pop-up. I hold my breath. Kinda scarry stuff...even for Holloween! I hope it is just a heat sheild!
