On my way to work today my car started making an odd noise that sounded like someone knocking on my roof/dropping an infinite amount of acorns on the roof. Only way to describe it really.
I drive an '02 WRX and have already tried a couple things, my main thought was the spoiler had come loose but I tied it down and still hear it.
So here is the run down:
It sounds like it might be directly above the front seats somewhere. The car still runs exactly as it did yesterday, no warning lights, no other noises, and still takes off like a rocket. The only problem is the noise is quite annoying and it starts its continuous knocking around 35mph. Lower than that and I need to be taking a turn or do some swerving, almost like something in the roof is dangling around.
I plan on checking the windshield seal once I'm out of the office in a couple hours as someone offered a wind theory, which was part of my spoiler theory.
