So I have found my uncle a nice 03. 996 c4
The dealers are fixing all the little niggels but it
Has PSE with the switch on the dash. And as far
As I could tell is make very little difference. Shiuld it?
I will ask them to look into this. Is it common to fail and expensive
to fix?
Hi Hoppo,The dealers are fixing all the little niggels but it

I have no idea about failures but, it makes a huge difference when the car is standing still at tickover. Have it set to quiet and start the car, after a few seconds flick it to loud and it sounds absolutely fantastic!
A 996 C4S (or any 966 I guess) with PSE is one of the best sounding recent 911s. GT3s are nicer and more tingly at high revs but that's about the only model, 996 onwards, that I can think of sounding nicer.
Hope you get it sorted. Make sure they do.

It may be that the PSE is always on but I guess it's hard to tell if you don't have anything to compare against...
Because the PSE goes into "quiet" mode between 30mph and 50mph it is a common mod to pull the control connector in the engine bay. When this is done you get PSE on all the time but lose the use of the on/off switch.
If you google for the PSE mod you should find a picture of the said connector (it's on the right hand side and brownish colour). If that is unplugged you could try popping it back on after which the switch should make a difference.
Of course it could be a genuine fault

As said above the switch should make a difference even when parked up.The dealers are fixing all the little niggels but it

If the null 30-50mph is still in place you won't hear a difference in that speed range.
Is it quiet all the regardless of the switch position - or does it sound like Click This!!?

These are the instructions for the 997 pse. 996 involves modifying a relay - a quick google search will reveal all.

And if you do it right you maintain use of the switch whilst removing the null at 30-50!
I believe so...http://www.renntech.org/forums/topic/2470-remove-p...
