Engine the same as 1.4 tdci in fords. No fault codes. The car has got problem with little juddering on 5th gear. No fault codes, IDS is a little bit limited on this one. No data for DPF which car has got fitted. New fuel filter, egr cleaned and moving freely. Now my question is did any of you guys discover some similar symptoms on this engine? I'm thinking a little bit in dpf side - dpf regeneration - car hot 5th gear etc. But limited on the diagnostics data.

Any help much appreciated
