The Blue Phoenix - E46 325i

[Senor_Taylor]

It comes and goes, so I doubt it's that.

Drove my car home last night. Parked. Pulled E-brake and put in first gear. Lock doors. Went inside. No noise.

This morning, unlock doors, put bookbag in back seat, pop hood, check coolant, get in, start car with brake in and in neutral, connect phone to blue tooth, release parking brake, shift into first and drive away. Noise

Out of all of those things, the only thing that could have affected anything is either the temperature (Was in 60s driving home last night, 54 degrees this morning) and the fact that I pulled the e-brake in between. Maybe I should stop ripping the e-brake handle so hard. As noted by Jake from my Reddish Knob Cruise video.
