I've just bought an A4 2.0 Turbo the weekend. It's an 05 plate with 53,000. My problem is it feels very sluggish for a 2.0 turbo. I'm not sure whether its me been used to quicker cars, but it really doesn't feel like it even has a turbo! Another problem I have is that it makes a really loud rattling/tappety noise on idle. Really doesn't sound right too me. I've had it on VCDS with no faults showing. Is it me or could there be something wrong?
