View Full Version : Subtle Winding noise 2.0T B7 after carbon clean up

05-10-2012, 02:45 AM
I Haven't had my audi for that long but I went ahead and did the carbon clean up. After doing this thought I have noticed a winding noise around 2200 RPM specially on 4th gear when putting more load on the engine. It doesn't do it on neutral or at least I can't hear it. It might have been there before the clean up but I started to listen closely after to make sure I didn't mess anything up.

-Ps, One of the fuel injectors stayed in the manifold when i pulled it out but I put it back on it's place by hand. Not sure if this did anything.

Any help will be appreciated and I apologize ahead if this problem has been discussed before.
Thank You

Could I ask what you used to break the carbon up ?
