in judder cdti 6th 7 engine and 1 5th

1.7 cdti engine judder in 5th and 6th
My 2011 astra j 1.7 cdti is juddering when accelerating from 1500rpm to 2000rpm in 5th and 6th (worse in 6th) no juddering above 2000rpm or when just cruising, only happens when you try and give it some gas. Changed MAF sensor, fuel filter, air filter and suction control valve. Cleaned EGR valve and MAP sensor, also had front wheels balanced, still no joy. Anyone had it before or got any ideas?
