Which you get when you have a boost leak. I suggested that you do a boost leak test and gave you the link to what to look for and how to test. It is very unlikely to be the fuel pump causing that code.

My money is on the Michelin Man hose between the cross-over pipe and the side-mounted intercooler inlet:

Thanks for the link to the boost leak test page. That's one I've clipped and saved.

(I've been wondering if I have a small leak as well - I hear something new like a whistle sometimes under acceleration, and the car might be a step slower though there are no engine codes and there is definitely boost. Maybe I'm imagining it, but better checked than ignored)

G40 Cam Position Sensor needed to be replaced on my car as well. The cool down trick worked a few times, but I'm glad that is resolved.

Hope you were able to replace the cam sensor using this procedure:
