Dude, you are waaay too patient for this crap!
Having to go back repeatedly and wasting your time, let alone not having the M5 for a month (at least) is totally unacceptable. Have you tried another dealer? Maybe that'll help. This may be a strech, but can you claim "lemon?" Just asking. But seriously, Good luck

As for lemoning (is that a word?) my car, I thought about that too but not sure if I can and I'm sure it'll be a pretty big hassle since I'll probably have to put everything back to stock. I love my car and don't want to through that painful process.

You might want to research the following.
When was you car built? On E60s(I know 545i's for sure)built before late 2006, the IBS(intelligent battery sensor, negative battery cable) was very susceptible to moisture damage. Ironically it was also positioned under a vent above the battery. In certain climates, evaporation and condensation inside the trunk would result in moisture forming around the bottom of the vent. The moisture would accumulate and drip on the IBS causing malfunctions that would confuse the car's electronics controls. Many batteries have been replaced as a result of malfunctioning or damaged IBS's. In late 2006 BMW redesigned the IBS to be moisture resistant, but kept it a secret from the owners of the cars with the susceptible IBS's.
