Hello group,

I have a 2003 C4S that has this clanking noise when decelerating under 4000 rpm.

Sounds like a chain rattle.

The car is equipped with PSE.

Sounds terrible!

Any suggestions?

JG :help:

It's fine on acceleration though. Just happens when slowing down.(It chatters)

There is no smoke or oil leaks.

I just had it's 15000 mile service at the dealer a few weeks back.

Thanks

Hello group,

I have to say, my Porsche Dealership gives awesome service. My car was scheduled for tomorrow a.m. .

I dropped the car off at 1p.m. this afternoon, at 5pm my car was completed. My hats off to them.

The noise issue turned out to be no more then a cracked tailpipe bracket section. (between the tailpipe and the muffler) They re-welded the bracket that the factory supplied on the car.

They also told me that it happens all the time.

Noise is Gone!!! :jump:

My only disappointment was that the mechanic did a bad job aligning the tailpipe. (it was aimed out to much like 2 inches.) But I adjusted myself when I got home.

I feel relieved that it was a easy fix and not serious engine problem.

Ciao

The exhaust recall that I am aware of was for "...exhaust tailpipes worldwide on 18,627 units of the 911 Carrera S and 911 Carrera 4S. This involves cars built between 20 April 2004 and 21 October 2005." This would not include his MY03 car.

Hi Loren, sorry to jump into conversation. i had the same noise. I managed to get tailpipe off ond there is a crack in the bracket. my C4s is from april 2003 but it was bought in germany. how could i check if there was a recall for that? and if there was one what do i do? call dealer and ask to fix it?
