0xD02D07 - Interface EPS (actual steering torque, driver, actuator, 49.0.2): invalid signal
0xD019C3 - Interface EPS (actual steering torque, driver, actuator, 49.0.2): invalid signal
After replacing the EPS rack in my car, I have not been able to get coding working correctly. The electric motor does not engage (steering light is on and errors are present). After running ISTA/P, the EPS module was supposedly encoded correctly, and no longer showed errors in ISTA/D related to encoding. The only thing that was left was to perform the End Stop Teach In.
Unfortunately, without the electric motor engaging, the wheel detects a "stop" almost immediately due the the force it takes to turn the wheel. Teach-in failed every time. On one discrete startup (I believe it was after the first hour and a half long ISTA/P session), the car started up and the steering rack was responsive. When the car started up again though, the light came back on and the electric motor was not assisting with steering. I tried performing the End Stop procedure from ISTA/D but with similar results. I have not been able to get the car to start again with a responsive rack even after resetting fault codes.
Just in case it matters, when I removed the original rack, the spindle pulled out/away from the wheel and was free. I had to knock it back in to reconnect the wheel to the new rack and did not get it lined up perfectly. Because of this, the wheel sits about 10 degrees right when the wheels are in forward position.
