when my mk3 is in 2nd gear and i let it run (no acceleration / braking what so ever) it lets out a sort of muffed squealing sound and seems to make the car jump a bit. i used to have a clio and had the same problem, but it happened in 3rd gear even when i accelerated and it turned out that the gear box was f*cked. i'm guessing this isn't the same since i recently had a MoT and service so maybe they would have seen if my gearbox was going?
anyway does anyone have any ideas? thanks
