I have a 52 plate zafira 2.0Dti. When driving at any speed, I press the throttle and the engine over revs a lot whilst giving me very little extra speed in any gear. i have no warning light on.??
if i pull back on the throttle and then gently push it again it will gain speed slowly, so i have adapted my driving to this. lol

If over revving with little change in drive, consider the clutch is slipping, try increasing revs slower, if speed goes up, poss clutch, what is it like pulling off on a hill
