Strange engine noise 2009 C30 T5 (with video)

Post by GregUSA » Sun Mar 31, 2019 11:18 am

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.

Open to any suggestions as to what might be causing this. It really just popped up out of the blue one day. Thanks - Greg
