159 1.9 Ti low speed judder


I have a pronounced judder occurring at low revs in 1st 2nd and 3rd gear mainly. it happens at around 5 to 10 mph in second, 20 to 25mph in 3rd. The whole car shakes and judders. Its a nightmare in slow moving traffic. For some reason it always seems worse after a long motorway drive. On returning to town driving the judder is accompanied by a harsh metallic tapping. I have just treated the car to a high concentration of injector cleaner and a tank of good quality diesel with 2 stroke added. While this has lessened the tapping noise a bit i'm still getting the juddering.

I have read numerous threads but not found anything which seems to fit my experiance. The car has had the DPF removed/remapped, EGR blanked/deleted and inlet cleaned. Has 52,000 on clock. The juddering has always been evident pre and post DPF etc.

My questions are, is this just a characteristic of the car or a fault e.g bad injector, clutch/flywheel, or something else?

What are the possible causes?
