Decided to use the BT Tool to check for some codes. Two relating to the fuel pump, i am not experiencing any cranking issues. I've had the fuel pump plausibility code (2AAF) before, i deleted it and it came back. Weird since i don't have a tune and am not experiencing any crank issues. Not sure what 2C6D is referring to, maybe my o2 sensor is messed up? Last time my exhaust was touched was when the dealer replaced my turbos about 3 months ago.

O2 sensors have been known to go bad. My tech just replaced a bank 2 sensor on a customer car yesterday.

Also, try replacing the high pressure fuel pressure sender. It's on the back of the high pressure fuel rail. Sounds like that may be causing your fuel pump plausibility and fuel pressure sender codes.
