This is my first post here at Ross Tech. I have an Audi A6 2.7t that stalled while driving. I rushed into the fuel pump and then the fun started. After realizing that fuel pressure wasnt the issue post pump I went to check codes. No communication across the board. I confirmed a soild 12v (with test lamp) at pin 7 of the DLC. Factory radio was installed. I ve removed all control units and no change in the readings at pin7. Now after removing the seats and checking all areas of the interior harness I have not come across any shorts or breaks in the wiring. Unplugging connector 17 at the pass A pillar connector bulk (comfort harness) will turn my light out. Yet with this undone and just the ecm plugged in there is still no comm. Cluster/ Comfort module have been removed for testing while just trying for PCM communication. I am stumped!
