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.

Hi Clifford,

Here are the uploaded YouTube videos:

- Revving video:

- Accelerating video: 

Your help would be much appreciated.

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.
