As the title says, when I turn the engine off, I can hear the sounds of solenoids whirring and clicking for about 30 seconds. Is this normal?

i hear all sorts or electrical sounds when off the s3. sometimes they start 30 seconds after shuting it off.

Same here - a combination of mechanical sounds and beeping type sounds for at least 20 seconds after shutoff.

I assume this is normal. The first week I got my A3 I was a bit concerned about it but then saw this video on Audi's website about the electromechanical parking brake and after you turn off your car it occasionally goes through some tests so that it is always properly working. The site says it does this only after every 620 miles driven but my A3 still seems to make noises more often than that.

Here is the video, the info starts around 2:10:

I get all sorts of noises from the solenoid in the car after shut-off and last up to 45 seconds or so after.

Sound really awful especially in the garage.

A friend of mine told me that solenoid noise is the car pumping oil to cool the turbo, by doing this it will proven turbo from the metal rapidly shrinking, nothing you should be concern about.
