P0174 and googled...says all over again most possible reason "vacuum line" leak
or maf, but think N54 doesnt have maf..only TMAP or something.even mechanic says very possible vacuum leak,because the sensor which report this error is before the precats.
which remap? also when someone takes the time to ask questions to help you out you should answer them....
ok so now you are stock or have another remap?
