1.6TDI 2010 Strange Engine Sounds

[ertdes]

Hi all,

I have an A3 8P 1.6 TDI 2010. I am hearing 2 sounds from the car and I do not know whether they are normal or whether something is wrong. No warning lights have come up on the dash and as far as I can tell, there is no loss of power. I have only recently gotten into cars so your thoughts and advice would be much appreciated!

Sound Under the Bonnet

There is a sound under the bonnet when the car is idling. Here is a link to a video of the car when idling:

And when the car is being revved:

It's a faint sound that can be heard in the background of the loud engine noise and fluctuates in pitch, it sort of sounds like a straight metal sheet being bent back and forth (not sure how else to describe it!).

Sound When Accelerating

There is a sound on the driver's side when accelerating, especially in the 1K-2K RPM range (above 2K the engine noise drowns out the sound but it is there). Here is a video of me accelerating the car (taken from passenger side so the sound may not be particularly clear):

The sound is similar to the one in this Youtube video but is more "airy" for lack of a better word:

Once again, your advice would be much appreciated!

I do not download anything from untrusted sources, so if you would care to put your videos on Youtube or similar I'd be glad to listen them there.

All I hear in the first and second videos is the normal diesel clattering. I don't hear even that in the third video. Unless you have other symptoms of engine problems you have nothing to worry about.
