I had this case few months ago. typical 1.9 Saab 9-5 for DPF remap and my officiousness EGR. Remap done corectly dpf solution from swiftec and after few days problem with egr dtc P0400. Before car went out from workshop i put new MAP sensor cause old one looks like nose of miner & plate betwen inlet and egr. after few day car came back with MIL and from german :) notlauf. i tried repace MAF but same shit.i have found abut 2-3 maps in flash done same as edc15 and rest of it by swiftec solution but nothing gets better. im lame or this ecu just dont like me ?

Post ori and mod.

don't do as stupid do on vag tdi !

there are better solutions

egr you can off or close it

I''ll post file tomorrow but after back to ori set <plate and map> still got this damn DTC :problem:

Im not sure which one is the last one

Both not correct and too many DTC erased.
