2014 2.0t auto. I have noticed that from time to time, when i step on it and drive aggressively the engine makes sort of a gurgling or perhaps rattling noise. It sounds almost like drinking and almost empty soda from a straw. It's definitely not a typical turbo noise. Anyone have a similar noise?

Thanks

Sounds like engine knock to me, are you running on 93 octane?.

It could be the growl from the lowend torque

91 is the best I get out here.

I'm assuming higher altitude then if 91 is tops. Still sounds like knock to me.

Agree with GJB that it could be knock. It sounds like it is fairly regular so it should be easy for the dealer service tech to hear. If it is knocking you want to get it addressed right away however it could easily also be a loose heat shield or other mounted item that sets up a sympathetic vibration/oscillation under certain engine operating conditions. My 2006 GMC Sierra turbo diesel had a similar noise that was cured by tightening the mounting bolts for a shield.

One other thought, have you been buying all of your fuel at the same station? If so try a different supplier for a couple of tanks.

Thanks for the input everyone.

To answer a few questions, I buy gas at a few different stations.

Also, I noticed that it makes the noise between 3k and 4k rpms right before the turbo starts whistling. Once I can hear the turbo, I stop hearing the rattling noise.

Check torque converter. Mine was a rumbling at about 2500-3000 rpms. Tightened TC and all gone.
