There is a certain driving style required to getting nice smooth changes, from stand still and brween first and second IMO. Certainly very different to anything petrol and pretty much everything else I've driven.
I think it's a combination of 'torquey' engine, sizeable clutch, clutch delay valve thingy and customary low ratio diesel first gear.
You'd definately know if you've got the judder though. Try reversing up an incline, that's when mine really showed up. Thought the car was going to vibrate apart.
