HELLO

Hello everyone, I am new for these parts. My query is as follows: I have a BMW 330i and sometimes if you go quickly it stays accelerated but does not walk and when it goes down then then it comes out. He doesn't do it every time. Once being at a rise when I turned back, nothing was walking and after several attempts smelled. Can the clutch be? It worked well. Greetings

Indeed, it is the clutch that has wear on its tile and this slide (skate) that is why it is a burning smell.
