I have a 2016 Audi A3 2.0t premium Quattro and every couple of minutes my car will have this really loud fan going under the hood. Is it supposed to be this loud? I feel like it’s obnoxiously loud but if it is normal it’ll ease my nerves a bit til I can figure out how to quiet it down. ---

What you’re probably hearing is the secondary air injection pump giving up the ghost. ![image](https://global.discourse-cdn.com/cartalk/original/3X/e/e/ee922d25a144d9ce09319f3d5b991b3107f6e327.jpeg) This fan can get so loud that it can sound like a jet engine. Tester ---

Is it something I need to fix? If not and it’s normal, can I do something to quiet the noise? ---

If that’s the source of the noise, the secondary air injection pump has to be replaced Tester ---

So it isn’t supposed to be loud? It literally just sounds like a super fan. The car runs fine it’s just the fan is very loud and can take up to a few minutes for it to stop after I turn the car off ---

Is it hot where you are? And are you using the AC? Because if so, that’s normal. Tester ---

Have you checked the coolant level? If the engine is running hot the radiator fan will operate at high speed. ---

It’s not hot where I live yet, I live north east U.S so right now it’s about low 60s mid 50s and sometimes I run the heat on if it’s cold at night. My coolant level is full so I don’t think it’s because I’m low on it ---

Did this noise just start or are you just now concerned about it. ---

I just got the car it’s used but when I test drove it the noise wasn’t there. It wasn’t noticeable until about two days after getting the car and when I told them to check it since I’m under warranty they said they found no issue. But I don’t think they really tried to debunk the issue since it’s a used Audi from Kia dealership so not their priority ya know-\_-
