07 335i DCi,dinan exhaust, jb4 g5

I was driving spirited and for the first time got limp mode and the Following codes show up:
Also, only goes into limp mode on map 0, if I'm on map 1 doesn't happen...

2F6C-exhaust fumeflap, input signal, guessing this one is because of the dinan exhaust, so not to worried..

These 2 are worrying me..
2AAF-Fuel pump, plausibility
30FF-Boost under-target possible boost leak... What should I do?? Thanks everybody

does it take long to crank on cold startups?

Only sometimes..

It's only happening on map 0? I think that's normal. On the ISO (isolated boost control) version of the jb4, map 0 is not meant to be driven on at all- it's just for gaining access to the obd port while parked. It causes boost under target codes because the dme and the jb4 are only partially interfaced and your boost targets will not be working right. The dme asks for a certain boost level but only sees something much lower. If you want stock boost levels run map 4, not map 0.

Not sure on the fuel pump code- it might be related. Try clearing the codes and running on map 1 for a while, then check codes again.

Somebody else told me the exact thing! And they said for the other code to not worry about it... Thanks a lot for your help! I am more relaxed now lol.

Right on. Happy to help, Mr Canadian.

Which version are you running? I was getting a 30FF when running map 0 and 4 with version 27.5. Terry told me that version 27.5 may throw that code on map 0 and 4 depending on XYZ. That's a bug, and should be fixed.
