The 2.0Tsi engine has a known "popping sound" at between 2000 and 3000 RPM. Many owners complain of the noise during acceleration, sounds like "pop rocks in a can" - I thought it sounded like engine knocking. VW confirms it is the wastegate on the turbo, but says it is normal. Along with the noise, I find it annoying that they have known about the noise for at least three years yet have not fixed it. Test drive with a purpose and make sure you can stand the noise before buying, because you are stuck with it once you take the keys.
Styling is great, handling and acceleration are excellent. Sound system is quite good.
Fix turbo wastegate noise. Reduce road noise into cabin.
