Strange noise from engine compartment (video)
I have a 2009 C30 T5 that recently has developed a very strange noise from the engine compartment. I couldn't describe it so I shot a short video for you. About the same time the noise started, give or take a day or so, the 'check engine' light came on and has stayed on (still on).
What really has me stumped is that this sound is loudest/most obvious at idle, or whenever my foot is off the gas pedal (or when I let up off the accelerator). The moment I press down on the gas pedal - the sound almost completely goes away. When I let off the gas pedal - the sound is back instantly.
The car was just in for regular service/oil change about a month ago. No obvious problems in the engine compartment were noted at that time.
Here's a link to a video on it: https://www.youtube.com/watch?v=1OIR...ature=youtu.be
Open to any suggestions as to what might be causing this. It really just popped up out of the blue one day. Thanks - Greg
