Please help me diagnose these codes (they're probably the same code from different scanners). I've searched and searched and there's no info on them for E9x.

08 E90 M3 w/ 55k.

Got a CEL immediately after starting the car with a "Reduced Power" warning. The car is in limp mode.

Scanned with a generic OBD2 scanner
P2138 - Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation

Scanned with a BPM Sport scanner and got
2B07 - Pedal value sensor plausibility
279D - Power management battery closed-circuit current violation
2796 - Motor emergency program activated
I suspect that 2B07 is the root cause of the other codes.

Tried clearing codes and they return immediately. After several days they went away (the car drove normally) then came back a day later.

For other cars, P2138 implies a TPS fault.
For the E9x, I'm guessing that it's either the gas pedal itself or the throttle actuators...currently leaning toward the former.

Any ideas?
