lts still got juddering from engine at 1500 revs when accelerating in fifth

That is because you are in the wrong gear, any car would do it. Its possibly OK at a constant speed and throttle but simply not comfortable with having to work from those revs.Change down to 4th or even 3rd and feel the improvement.

Hi iv got a diagnostic scanner and there is no codes only for glowplug device , it seems to be fuming as can smell gases in car and on Rickover when you pull up and put clutch down it will Rickover at about 850 but then drop down abit and feel like a vibration ,,, also on the intercooler pipe that goes from cooler to left of engine as you look at from front of car ( goes to near cambelt ) iv noticed it been rubbed a bit but not through , would oil and filter changed make difference thanks

Hi thanks checked brakes and all seem fine , I'm thinking clutch as when I change gear I will accelerate then when I put foot on clutch there is a noise , so could be clutch but it was doing this when I bought it and never got any worse and was good on diesel , would changing oil and filters be worth a try

Hi I was told that my astra juddering was the turbo actuator sticking but got all bolts out and couldn't get heat shield off to get to actuator ,does anyone know easy way to get shield out thanks
