My turbo started making a high pitch "whistle" or whining noise a few weeks ago, especially when accelerating in 1st, 2nd and 3rd. At first, I could still hear the turbo boosting and it seemed to be driving okay. However today, there is a whining noise that has suddenly become MUCH louder and happens consistently even when touching the accelerator lightly. When revving in neutral, I can also hear the whine. It's an "air-y" sort of noise. I can't really hear obvious scraping coming from the turbo but it's really hard to tell. Is my turbo stuffed? Thanks. video-1569228217.mp4 video-1569228261.mp4

Hi. I'm new to this forum as I've just bought my first Audi A3. I was hoping someone here can help me! I've got a 2.0 TDI Quattro and noticed a couple of days after buying it that there is a whining noise coming from the rear of the car, sounds like near side, when i lift off the throttle and decelerate from 80mph. The noise can be heard at lower and higher speeds but its most noticeable between 80 down to 70mph. Another couple of things to add is that the noise goes away when i apply the brakes, and the noise is still present when out of gear. I took it to an Audi specialist and the identified the following: - No abnormal noise from wheel bearings - NSR brake disc face corroded/lipped/scored - Suspect scraping noise is brake pad picking g up on brake disc lip - Rear prop shaft bush is split, but with correct movement of the outer weight - Rear diff drive shaft oil seal has slight leak but oil level ok - Rear diff output shaft has excessive movement, expect this is due to a worn bearing in rear diff, expect this is the reason for the noise. Based on this, i took it to a gearbox/diff specialist for a refurbished and they were reluctant to work on it as they weren't convinced the noise was from the diff. Another thing to note (not sure if relevant) is that when changing lanes on the motorway, the rear of the car squirms a bit when moving over the middle of the road/white lines. Anyone else experienced this or know what the noise might be? Thanks in advance for your help!
