For those owners stressing over this, Audi extended the warranty on the air/oil separator to 120K miles or 10 years from original sale date for eligible vehicles. It’s all over the internet. And Slim is right; it is one of the most annoying sounds of all-time 😂
I drive a 2017 Audi Q7 I had my check engine light come on and off within like 2 hours time. This happened 2-3 weeks ago.. I scanned it right when it happened and it came up with a code for “super charger sensor” then disappeared… Nothing noticeably different while driving what’s so ever.. but a day after the code popped up and went away I start hearing a weird clanking/grinding like noise only when idling, As if one of my pulley went bad. I tell this mechanic that looked at it yesterday exactly what I just explained right.. So he looks at it and tells me that my supercharger was the cause of the noise, as well as the supercharger pulley tensioner.. Last night I have another guy look at it and without even taking it apart he looks, listens and tells me within 10 mins that it’s my water pump pulley that is bad. He’s 1000% sure not my supercharger. He said I would’ve had black smoke coming from my exhaust , loss of power along with some type excessive whining; in which none of this I experienced.. In your experiences and from the sound of this situation ; what are your opinion’s on this? Every answer and/opinion is greatly appreciated and will save me a few strands of hair that I have left on my head
If a pulley goes out it is easy to diagnose as it will grind and wobble when it goes bad if the super charger is going out you will notice a major difference in performance its possible a pulley Is locking up making the belt slip and not powering the super charger to manufacturer settings with would trip the code you can use a prybar to listen to pulleys like a stethoscope start car and put end of bar on pulley bolt I will make a video showing the technique. I hope I was able to help all I ask is for people to sub to get me to the 1000 sub marker so I can get monetized
The more load you put on the engine the more air it will pull and the louder the noise will become and as for the thermostat it calls for 5.0 hours of labor to change
Pop your oil cap and if the noise goes away I'm sorry to tell you it is a faulty part if the noise persists please let me k ow and I will try to help you out best I can
So I have a 2016 Audi SQ5. I took the oil cap off, turned the car on and the sound disappeared but when I put the cap back on, the noise came back. What could that mean?
