Z4 Roadster (E85) Battery drain

I am still having a problem with my battery draining over a two day period. I did the fuse thing and pulled them. I could not find a fuse drain.
The next step is to take it to a BMW dealer and try to hold on to my wallet.

I just noticed somethimg last week. I do not use my radio much, so it always off when I turn off my key. I noticed when I start my car the radio automaticly comes on. Is that supposed to happen? May be it never really shust off.

I have the same issue, have you tried this test? When you do test it, let the tester sit for a few minutes. With my car something is turning on for a couple minutes but then turns itself back off few minutes later.

It's weird lately my car has been starting after 3 days of sitting. Also I think the radio does turn back on when you start the car.

See, the problem you guys face is those aren't actual, BMW-built Z4s. They're clearly Transformers disgruntled at being left alone for long...

Only suggestion I can add is to find a non-dealer mechanic and form a relationship.

Morning...Identify the radio circuit and pull the fuse. See if the problem continues. Enjoy your day-Gnatthecat
