    Can you see the pedal potentiometers moving with your diag computer?

    PWG moves when I depress pedal, Mdk does not. To make this move do I need to get to throttle body?

    Then it's either the throttle body itself (check connector, sometimes it's difficult to seat connector properly), wiring, or power to the MDK.

    With boot off, nothing moves . Can hear click at body, when pedal pushed down. Moving body by hand does nothing. Normal operation is one of the sensors goes towards 0v from 5v, and the other sensor goes to 5v from 0v . PWG move up, MDK is stuck at 4.98 poti 1 poti2 0.01

    Okay I feel like a dumb a, with all this messing around. I apparently did not have connector to body on tight it came off when checking over it. But on good side now I have INPA reader, AWESOME !! I guess it did help, MDK showing not moving. Still not sure if other body was bad, I had different one to replace it with. A grateful thank you to bmw dirtracer and 328 power 04. YOU GUYS ARE AWESOME

    Glad to help, rocket. Just remember: If mistakes make one a dumb-ass, then I'm a bigger one than you'll ever be...... Mistakes are how we learn. Oh, and you can call me Chris....

    Thanks Chris. My name is Rod . Know I see what the INPA program can do, I should have set it up earlier. For the 20$ it is a great investment.
