Over the past couple of months I have received (what appears to be) incorrect warnings when starting my 2007 328i. Roughly two months ago I got a couple of indications in the dash that a bulb is out, but could not locate the problem. A few days later the warning light stopped appearing and hasn't come back for a about six weeks. Last week I received low coolant warnings that disappeared upon a restart of the engine. I don't want to spend three hours driving to and then waiting at the dealer if they are going to tell me they can't find anything wrong.
