S5 engine in limp mode
Code pulled indicates its the OMP but it has been replaced as well as the ECU. Any suggestions on what to check? Numerous things have been checked on this car and nothing seems to fix it.

If the code pulled is from the ECU says its the OMP, and the car is in limp mode, than it's the OMP that's causing the ECU to go into limp!!!!!
Follow the prodedure outlined in the FSM about testing the OMP and then asscociated harness.
If the OMP was replaced than it's more than likely the wiring. Could be a bad OMP too....

Yeah, check the OMP obviously first, then go through the wiring and make sure you don't have any shorts/etc, if all is good up to that point, plug it back into the ecu, unhook the battery for about 30 seconds, hit the brake a few times, then plug the battery back in and try again.
