Recently I had to send my headlights out to get some work done on them and after about a month of waiting I finally have them back in. However, my car has been sitting for the whole time the lights were gone and I haven't been able to drive it. Is there anything I should do before starting it up again? I was told by a friend I should probably turn the engine by hand first. Car is a 2008 BMW 335i if that matters. Thanks in advance for any help!
