One problem related to software has been reported for the 2006 BMW 330. The most recently reported issues are listed below.
I had a bad experience this morning. When I got into my car, it wouldn't start when I pushed the start button. Instead it had an icon on the dash of the steering wheel with a lock sign on it. I pulled the fob out and put it back in a few times, trying to start the car every time, but no life. This is a very weird problem. The steering wheel lock wouldn't release. I tried to get it started for over 30 minutes, still unsuccessful. I did some research on the internet, apparently it is a common problem in the 06 and early 07 models of the 3 series. In mid-07, BMW stopped putting locks in the steering columns. Apparently, this problem has to do with the electronic lock power draw when starting the car, and a software update normally fixes the problem. If the software update does not work, BMW replaces the steering column if you are under the warranty. All my updates are done because I took it to my BMW dealer on 11/14/12 and they rechecked everything. . Read more...
