PSE (Porsche Sport Exhaust) not functioning

Recommended Posts


Hopped into my car this morning to discover that my PSE electronics are not functioning. Car defaults to loud and when I press the dash button to quiet the exhaust nothing happens. Indicator light comes on when the dash button is pushed, but nothing changes at the exhaust. I looked at the fuse box to see if there was an issue there, but everything seems in order. Any similar experiences by anyone here and suggestions as to what the issue could be? Car is extremely low mile (20k), so the issue should not be wear. I am suspecting electronics or vacuum problem with the baffles ?? Any thoughts?

Thanks in advance

If you have a bad enough vacuum leak you will eventually get a CEL.

If you unplug the solenoid at idle you should hear a change and see if it is one side or both (there is a separate vacuum diaphragm for each side).

If only one side is muted when you plug it back in then it is a bad connection or bad diaphragm on that side. Unfortunately if the diaphragm is bad that likely means a replacement muffler.
