I have 2 questions about my Mercedes CLK
Mercedes CLK 500 from 2002 has 306hp, but when I looked up how many horsepower my CLK 500 has it says 367hp. Mercedes CLK 55 AMG has 367hp. My car is registered in Sweden as a CLK 500 and I wonder if it is imported as a CLK 500 instead of the CLK 55 AMG because it should be much cheaper taxes.
(if possible)
Heres a picture of my car

My second question is, it has started ticking/knocking somewhere around the air conditioning and its a strange sound. It sounds like something is stucked inside.

Thanks
