I got my module back, i tested my cps and it is good. How do i test my dme?

 

That is going to require access to a Porsche factory diagnostic system such as the current PIWIS or earlier PST II.

So i guess everything else is ruled out and it is the DME, any suggestions on how to test or replace it?

See the above; testing or replacement is going to require the Porsche diagnostic system......................and bring money as a new DME is about $2K sitting in a box on the counter, plus and hour or two of programing time, if it really is the DME.......

Do can i find a used DME and put it in? 

[Justin Boisclaire]

Just not sure what my next step should be. Not sure what else I should diagnose to rule out the dme. Not sure if I should just part out the car and cut my losses.

Even a used DME (same version number) would require reprograming by a PIWIS system.  The DME in these cars is the center of everything, even your odometer miles are stored in the DME.

The only way to rule out the DME is through diagnostic's, so there is going to be at least some $ involved. And just as a side note on the subject, in all the years we have been working on these cars, I have seen very few DME failures, fewer than I can count on one hand.

Well i am happy to say she is now running! I am also happy to report it was an easy fix. I am unhappy to say i am at fault and somehow dropped e1 fuse and it was missing, i just overlooked it. Oh well she's alive!

Thanks for all the input from you all.
