So I have a BMW 545i that's running like crap. The idle is rough, it has about 50-70% power, but it's not throwing any CELs.

DIS shows the following:



The car DID have a single coil (or plug) go out about 3 months ago... it was misfiring and throwing a code for cyl #6, so I just replaced that plug & coil and all was well. The car is also going completely battery-dead if I let it sit for more than two days. It gives me the "High battery drain" warning in iDrive as well.

Any ideas what to try? There are no BMW mechanics in the area (SF) that I've found (ones who can actually diagnose the issue). Should I just buy a bunch of coils/plugs and replace all the misfiring cylinders?



Or, if you know of a good BMW mechanic in the SF area (I'm in Parkmerced) let me know!

Thanks a ton
