1st Post - PSE


Recommended Posts

Hi all

Have been reading this site for some time, and now I have my Carrera 4 I am constantly on here and thought it about time I posted.

I have just had the PSE system fitted to my 2001 car and whilst running the car over the weekend I have noticed a "flat spot" in the noise coming from the exhaust.

Under acceleration in 2nd/3rd gear the exhaust note changes from the deep sport sound back to the normal quiet sound of the original exhaust, it is only evident when running through the 2500rpm to 4500rpm rev range but I am not happy with it.

Has anyone else experienced this with their PSE installation or have I got a Friday afternoon job?

Thanks for a great site :clapping:

I have got the full system installed with the dash mounted switch to quieten down the exhaust when I want too.

Is there an automatic closing of the valvle that happens at a pre-defined point relating to speed & revs then?

If so can it be overridden without harming the functionality of the dash switch?

Cheers

Ollie

To meet European noise laws the PSE goes back into "normal" mode between 25-45 mph. This "feature" can be disabled by removing a 4 position jumper from the relay (#23) which controls this. There are other posts on this webpage on how to do this. It's pretty easy...the only hard part is pulling down the relay panel from behind the dash. Takes a little bit of twisting around and I found it easier if I took out a couple of the larger relays which were getting in the way (I put them back in when done...of course).

By doing it this way the button on the dash is still functional...ie you can turn the PSE off "manually" so not to p*** off your neighbours in the wee hours of the morning.

I did it myself this weekend to my C4S. Have fun!

Got home, said hello to the wife and within 10 minutes the metal jumper bar was out.

Thanks Loren for the guide, perfect!

Car sounds how is should have done from the factory now.

On other post, some people experienced the "Automatic Central Door Locking" function is not working correctly after the mod.
