Pipes on the new Audi A 3

Pipes at the new Audi A 3 Hello Audi driver(s), I’ve fallen the proud owner for about 5 months now. Point one: Since about 5,000 km I hear an ever louder whistle noise in the interior at speeds between 1500 and 2500 rpm (I think comes from the passenger side) After I was in the workshop and the car master looked at the car and the whistle also heard the statement: “It’s quite normal. After a certain mileage The turbo is driven in and gives off the excess power at the speeds between 1500 and 3000. This creates the whistle”. STOP AUTO!!!!! Maybe that’s how it is. I drive now my 3’th TDI Audi and none of the predecessors had this problem. It is annoying and besides, I demand a new Audi A3 2.0 TDI (Ambition) at a purchase price of approx. 33,000. Since I am on the road a lot on business I am so close to 30,000 on the speedometer. The car makes me a lot fun. There are, however, a few comments from me which do not give me a negative on Euro “NORMAL PFEIFEN” if the old models went without it. Point two: The high cheered full rubber windscreen wipers are not really helpful in the winder. The windscreen wipers become hard and scratch over the whole windshield. A change does not really bring a success. Point three: It’s not so wild but it bothers. The lighting in the trunk. If you already offer a light package as an extra then look but please that shines more than a “Fire – Flame” in the trunk. I would be happy about an answer from you but also from AUDI (just to the whistle problem). Greetings and good driving
