my 2.0 tdci has a slight juddering at around 1750rpm
its done 33k miles and is a 07 reg (old shape)
its most apparent in 3rd or 4th gear when doing a constant speed, and when cold.
i have had the ems updated to the latest software
any suggestions

check the intercooler pipe for splits, this is the large pipe on the bottom of the egr valve.
