How to stop ticking noise in my 2003 Porsche 911 C4?

The noise comes from the passenger side, in front of the muffler. I have read that a faulty EGR valve can make such noise. Reading further, the author recommends disconnecting the electrical connector and see if the noise stops. I want to make sure I won't cause further problems. Also, there are several EGR lookalike parts. I've scoured the web for a photo of a Porsche 911 engine showing the valve, without success. Any help will be appreciated.
