I think your main culprit is passive tank.This 4BCD code refers to the error in the level senor.Unfortunately it's quite a common problem.Remedy is to get a new tank or get it repaired from
these guys.
Your second code 46EB is i think is just the after effect of your first error code (malfunction in the level sensing system of passive tank).
Best would be to run test plan using BMW factory diagnostic software like ISTA before taking apart anything.
I hope it will help you to understand the problem.
