What is this noise? (Video)

P7X · 04-19-2012, 03:58 PM

Only had the 1er for 2 months now still getting to know it but im paranoid when it comes to car noises. Been playing around with the GoPro trying to find good angles and noticed this noise (video) at 9 secs and 14 secs. I just installed CP-E DCI yesterday, could be related but looking back on other vids I made I can hear the noise as well, DCI might have amplified it, don't know. Does it in gear and out of gear under heavier acceleration.

Wastegate rattle? (Based on what I've heard, dont think so)
Injectors?
Lifters?
Something else?
Normal?

At the 9 and 14 second mark the noise seems to be a higher pitch, almost like you are revving it again. Is that what you are talking about?
