any updates on this issue?

soon as come car comes back i will post it..next week it should be hereif it helps we had f30 318d and it was also lacking boost but it had only error on MAF seonsor..after testing drive i saw air mesaured on MAF was lower then needed and boost also..but at the full throttle egr was at 0 and boost and MAF value was ok..so we did EGR off and unplug it so that EGR doesnt open..with plugged egr it was not ok but soon as i unplug it i had boost and air..so this one was easy fix..i didnt do egr off,this solution had to have egr unplugged but i guess there is soulution with plugged..i hope this will help someone..and soon as second car comes i will update...

had similar issue with n57, for some reason there were no boost, after disabling egr all was good. so i think egr is open and ecu does not see that is open, and there for no errors are present.
