So frustrated, hate these inconsistent, intermittent problems so hard to properly diagnose.

So this morning, it did it again, started up rough from the start. CEL flashing until it normalized then drove off.

But today, 2 min into driving coming to a stop light, it started flashing for like a sec and went away again. Today was pretty cold, car was covered in frost all over.

I seriously don't think it's my levers now. Because according to the SIB, I should experience rough idle AFTER 60 sec of cold start when it's switching from 6mm to .3/.8mm lift. Mine just starts rough from the start (again sometimes, sometime it does idle normal and goes into rough after 60 sec or so or sometimes doesn't do it at all!)

Does anyone know if when DME adaptation is reset so does the Valvetronic adaptation?

Been reading about E46, E39, E60, E70 guys talking about VVT adaptation reset? Does it apply to E53 N62 or is it all controlled by the DME?

I do see a part number for Valvetronic Module that is separate from the DME.
