When buying a new tire at car shop, they pumped the new tire and it popped loudly, is that normal?
This is absolutely normal. What's going on is they are seating the beads of the tire against the rims. In order to get them to do this, they have to over pressurize the tires a bit, which then allows ...

What is that sound?
It is the sound of the fuel pump priming and pressurizing the fuel lines, which is absolutely normal. VW likes to use the opening of the driver door to trigger fuel rail pressurization.

How can I be sure that a rod knock is actually a rod knocking?

Why is air buffeting worse for most cars with the rear windows than the front windows?
In the simplest terms possible, the windshield acts as a spoiler or fairing, pushing the air out and up as your vehicle gains speed. The air naturally will push back to be along the side of the ...
