I’m in northern WV. Looking for someone within 75 miles (western pa Pittsburgh and east, eastern Ohio Zanesville and west, wv Morgantown and north). I can come to you. Just need to do a PSM coding and swap out after replacing my PSM module. My Autel Ultra can’t do it. May be interested in buying a used one if price if right.

 

What year is the car?
I have a PIWIS2/3 emulator (VCX SE), which is ~05+. Have not tried it on a 955, but 957 and onwards it works great.
PIWIS2 clone will do 96 to about 2018, and even pre-96 with the right adapter. Must be a clone, not emulator (all emulators are ~05+).
I'm about 400mi east of you though.
