Hello. I have a problem with my car, namely the clutch pedal. Namely, once every 10-20 times the pedal "comes back" very slowly and can grind in the crate, and it happened two or three times that I had to pull it up with my foot. The clutch itself works flawlessly, it catches virtually from below. Toy car is a3 8p 2007. Where to look for the reason? Clutch / pedal pump in itself or is it likely to be a clutch in the box? Regards
