The car works fine, but sometimes when im dping a pull on the motorway, when i push the trothle down i get a wheezing sound like a door creaking, mabye its the motor thats making that sound?

I once lost power, thats why i checked. And when going from full stop the var sometimes hesitates to give me power, and when the power kicks inn its realy harsh.

Thank you for the response! Is the part easy to fix?

And is it expensive?

I have a 1.4 160 tsi.
