Does anyone with the A3 1.8 TFSI engine have a rattle type sound coming from the engine from around 1500 to 3000 rpm up till you hit around 40mph? I'm collecting my car from Audi tomorrow after the have looked at it and described it as a "characteristic" of the car. It's actually more noticeable if someone else drives the away from you. Any opinions? I will be asking to test drive another car which they claim will do the same thing.
