    PSE has a vibration/rattle

    I have been getting a vibration/rattle coming from the rear of my MY05 997S. It happens on startup and at low RPM (under about 2500 RPM or so) and goes away after that. At first I thought it was maybe some kind of heat shield on the exhaust that was maybe loose but had no idea if there was even a heat shield to come loose. I have PSE and have had it unplugged so it's always on (loud) and last weekend I plugged it back in but didn't ahve a chance to drive it until now and when I did, I noticed the vibration/rattle wasn't quite as loud as it was when the thing was unplugged but it was still there at low RPM... Has this happened to anyone else? Does anyone know what it could be, (obviously without hearing it)?

    Re: PSE has a vibration/rattle

    Try stabilising the tail pipe with your shoe or something while someone accelerates the car to try to reproduce the rattle, if it goes away it may be that one of the supports for the exhausts has broken loose and hence the rattle. This has been reported in the MK-I before. If this is the case, the OP can weld it back in a second and as good as new.

    If the rattle is more internal and not related to the vibration of the muffler itself, then it could be a resonance valve inside the PSE that has gotten a bit loose too.

    I was guessing just about that, I will try the tailpipe thing and see if it could be a mount/support. If it's not that and it is one of the valves inside, am I out of luck or can that be fixed somehow.... I'm leaning towards the something loose inside theory, since when I put the plug back on and the valves were not in the wide open position, the noise was less.... but who knows...

    Re: PSE has a vibration/rattle

    Is it always on startup, and when the engine is cold?  If so, this is normal.  Also, PSE "always on" will mask the problem.  Try switching the PSE back to normal, ie., reconnect the connector.  The next morning, start the car up.  You should hear the rattle even louder. 

    If this is not the problem, than take your car in to have a tech look at it.  I recently had a rattle which was fixed under warranty.  If you want, I could check the work order to find out exactly what it was.

    It happens at startup and when it's cold but it continues at low RPM when it's hot. I did have it unlpugged and "always on" and when I put the plug back in, it actually was less noisy...

    Re: PSE has a vibration/rattle

    I had the same exact problem with my C2S. It only happens at a certain point when you barely press the throttle. I took it twice to the dealer. First time they could not hear it. Second time they barely did and decided that it is normal with PSE. 

    I gathered that not everyone would realise this rattle since it is barely noticable, given the fact that it happens for  seconds and not all the time.

    My noise, if someone couldn't hear it, they are deaf, it's definitely loud, so maybe it's still a PSE thing but it's a loud PSE thing.... and should not be considered normal.

    I have no rattles in my PSE
