Okay, as we all know Bimmers have the 20 min. rundown protection. It's worked for me in the past. But a few days ago, I noticed something weird: it's been 40 minutes since I shut off the car and my radio is still on. I was feeling half amused and half worried, so I started the car and on she went. I tried again today to verify, this time an hour long and nothing, no cutoff of any kind. What say you, fellow E90ers?

Mine shuts off around 10-15 minutes or so, notice it when I have it running while washing the car, I have to keep turning it back on.

Do You Have Comfort Access? Is Your Key Inside The Car When You Are Waiting On It To Turn Off?

Not Sure If That Has Anything To Do With It, But I Would Check Into That.

Don't think it does, I usually leave my key in the slot and still shuts off.
