It is a good suggestion. After checking for excess oil getting into the intake, resetting the KAM (Keep Alive Memory in the PCM) is the next recommended step IMO - if he hasn't done it already (P0603 might indicate that he has tried changing the PCM program, which may also mean he has tried resetting the KAM).

Hopefully it was simply a fuel issue, but the P0148 is thrown when your rpms are "higher" than the PCM is expecting (monitored by the "Diesel Engine Power Monitor"). Usually that doesn't happen with a tank of bad diesel, but who knows.
