The description for (the very rare) P2882 and P2883 seems to be the same as for the much more common P0171 and P0174.

Wonder what the purpose is of the P2882 and P2883 from BMW's point of view.

If the car seems to be running fine, might be worth having your independent tech. erase the codes and then see if they come back, and under what operating conditions (e.g. cold start, full throttle, etc.).

Small chance that they were just an electronic gremlin and won't return.

But if they do, one quick thing to rule out is an aftermarket air filter - they have been reported to cause the P0171 and P0174 codes.

Changed your usual gas station recently?

Other than that, it can be a hard one to chase down and often ends up being the crankcase vent valve.
If your low 46K miles involved a lot of very short commutes or shopping trips, that could be a good possibility.
But even so, a few E46 owners have done that as a last resort and still not fixed the SES light.
