120908

Anyone?

What's the car doing? Can you use another code reader? I tried googling the codes and nothing comes up.

Fifth gear WOT goes into limp mode (drivetrain malfunction) and through jb4 it gives me those two codes. Doesn’t happen all the time but out of three full WOT runs it would go in limp mode.

Is the charge air system coolant full? If IAT gets hot it can shut off boost.

I will have to check!

Did you clean the maf sensor and check the connection? You can swap it to the other side and see if the fault switches side.
