So I have had a hard time resetting these codes and getting my car out of limp mode. Every other drive though it has full acceleration, then the next start it limits me to 20mph.

I have a major engine issue with my 2006 330i. I get a "major engine malfunction, reduced power" error. P1056 code says it's the VVT or Valvetronic Motor. Long story short, I left my lights on and ran the battery down, jumped the car and it has freaked out ever since. Limited to 20mph.

I have switched the battery and installed a new Valvetronic Motor. Still getting errors on my screen.

I have tried the OBDII scanner and reset and the codes come back.

P1056
P1047

I have a Bavarian Autosport Fault Code Reader/Reset Tool, and it is giving me these codes:

2a3d valvetronic, adjustment motor: input signal
2a39 Valvetronic, adjustable range
2a3f Valvetronic, servo motor: power supply

Any thoughts would be very much appreciated.
