VW Passat TDi Engine code AJM year 2000 system EDC 15P - Missfire and judder Archived Message

Misfire or judder. In 4th gear between 2,000 and 3,000 rpm judder, then above 3,000 you can still accelerate up to 5,000 with no judder. As soon as revs drop to 2,000 and foot hard down, judders between 2,000 and 3,000. No loss of power, does not feel sluggish.
Have checked :- MAF sensor - ok.
EGR - ok. Wiring to injectors - ok. Fuel for contamination - o.k. No air in fuel system found.
No fault codes
If MAF or Turbo wastegate is disconnected no judder felt, but this could be because engine power is reduced.
Wondered about dual mass flywheel but unsure how this would affect running if a problem.
Any help would be appreciated.
