Nah, can't really hear my turbo at all. Not compared to my old car, which you could hear whistling away...made you think there were sirens sometimes. Which engine have you got? Or what spec? It's easier to distinguish what level of tune your engine is from that.
Oh I can't say then. I've the 1.6 126bhp model. Still not a slouch though. Compared to my 140 2ltr passat it is probably a little quicker. Like I say though I can't here a single thing from the turbo. In fact one of my friends last night even asked it was a turbo or just diesel as he couldn't here it. Maybe check the oil or have it changed see if that cleares it but it maybe just common to the model
