Hello everyone, I recently purchased a 04 TDI with the 5 speed automatic. whenever I come to a complete stop after the car has come to full running temperature the transmission will shift to neutral, but when its cold it runs and shifts perfectly, you can get it to go back into gear sometimes by moving the gear shift into manual mode. engine codes are P2196 for O2 stuck rich and p0501 Vehicle speed sensor A range/performance. thanks all
