Hello Scotty, I have a 1999 VW polo. When I try to go up a curb from a stop my car has very hard time doing so. I rev the engine but the clutch is slipping and I can hear sound as if it was bouncing back. When I drive on the road I don't see the clutch slipping, when I let the clutch out quickly the engine goes out as well. Should I replace it or is there some other way to fix it.

relace the clutch, it should never slip
