Gentlemen... I’ve gained a wealth of knowledge in the last 9 months since joining and want to thank you all. I have an issue with my Jetta with DSG as stated...sounds like a slight sound of a propeller driven plane doing a flyby. Sound pitch changes at 65mph with cruise set, and definitely pinpointed it to the engine as I can drop in neutral and noise is gone. I’m thinking possible turbo issues? Car has 136k on it and to the best of my knowledge turbo is original as I’m not the original owner. Fuel mileage has dropped as well...was averaging 42 now down to 37. I appreciate input and thanks in advance for any replies.
