Tonight after putting my 09 a4 2.0t in the garage I heard a sound twice. It sounded like air pressure being released, kind of like airlock breaks on a truck but quieter (yet still noticeable). Was wondering if anyone knows why this happened? Also it made me nervous cuz my fan didn't go on to cool the engine.

If it makes a difference I was pushing her a lil bit. An is250 tried messing around with me.

Thanks.

 

I hear that kind of sound all the time when I pull the button of electronic parking brake.

 

hm.. Im not sure if I put on my e-break, i will check when I get in my car.

I know I hear a sound when i open my door and the e-break, but never heard this air pressure sound.
