X-Type test drive – where did the sounds come from?

Hi, I’m recently a X-Type 3.0 Sport Bj. 2004 tested. The car is out of the question for different reasons, but I noticed a few noises during the test drive, which I would like to know more about. 1. If you let the car roll and then press the gas again, there is a strong ruck when you switch from the push-off to the acceleration paired with a clearly audible, dull SChlag. Is this normal with the X-Type? 2. If you drive in the 5th gear, you hear a clear fieping especially in the partial load range and at low speeds. At high speeds it was no longer to be heard, but can also have been well on the higher noise backdrop. In other gears it was not to be heard. 3. When driving, a kind of squeaking was already seen when small movements of the steering wheel, as if rubber were rubbing on metal. Are the noises known to anyone or perhaps even normal? Greeting, Nico.
