The DPFE is below the EGR valve, bolted to the block. You can't see it very well as it is hidden by the EGR valve & other hoses. Best viewpoint is from the driver side of the car, put your hand on the EGR valve & look straight down from there. I'll e-mail a picture to you & MYFASTSE.
The originals were aluminum body. The new ones are black plastic. Try the test, you could save yourself a bunch of money & time. First thing to do (if you haven't yet) is to clean your Throttle Body (TB). Be sure to get the EGR passages behind the gasket cleaned up too. Huge difference, & lots of info on that in this site.
By the way, the name is Tour de Force (not france).
