Hi this is my first post ,my problem is that when the car is stuck in traffic when pulling off in first gear I have a clutch judder .I bought the car in Nov  15 the garage told me that it had a new clutch fitted the car has covered 5000 miles from when I bought it. I would be very greatful for any advice has it is rather annoying problem.The car is an Astra 1.6 sri 5 speed gearbox ,Thankyou..

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?
