I just found the above topic on e46 fanatics forum. It sounds like my lean code problem, his about 8-12% high long-term fuel trims (mine are consistently 10-12% high) and 48 psi fuel pressure ( mine's 49 psi).
He replaced his fuel pressure regulator:

"Out China fuel filter/Regulator, in German Malhe . Fuel trims better. Fuel pressure 52 psi"
|
and his long-term fuel trim readings improved.
Later on, he also changed his MAF, and ordered a new oil cap, too, to bring the long-term fuel trims to normal:
Quote:
"Found last problem.
After changing MAF trim reduced to 4-5 %. Then I noticed oil around fill cap. Checked cap and found gasket with a preset grooved from age. Reversed gasket and ltft reduced to 0-2%. Have new cap on order"

I've already changed my cap & seal, so maybe a new MAF is in my future too.
