I just purchased a 2008 A4 2.0 T , 4 cylinder turbo with 16,000 miles on it. I am pretty happy with the car's performance except for the noise levels. The car seems noisy compared to the other cars that i have driven & this seems to a worrying factor for me. I could'nt notice much during the test drive for some reason. Is this common among all the audi's ? I have read reviews that AUDI's are noisy because of the turbo engine. Is there any way i could the noise levels by getting something done. Waiting for your valuable responses on this.
