    What is this start up drone?

    I have 35K on my 2005 Z4 2.5. Often times, but not always, when the car first starts, there is a droning sound that appears to come from the right rear of the car. The drone always disappears after about a mile or two. The only thing I can think of is that when I first got the car in 2005, I installed a factory alarm system that entailed dropping the right rear quarter panel and some sort of harmonic sound is set up due to some loose fitting part that is vibrating???

    Although the sound was intermittent, I was lucky enough to have it present when I stopped by my indy mechanic. Sound wasn't there when I left the car running to get him, but I then shut the engine off and sound came back with the restart. He said that it could be due to one of the belts. The sound usually occurs when starting the car and then goes away while driving. no need to do anything until the sound becomes more constant.

    Its the electric Fuel pump in the gas tank vibrating. Mine did the same but usually only when the outside temperature was betweem 65 and 75 and it would go away in a few minutes.
