I have changed the injector itself and done a leakback test which is OK, so is fuel correction. No other codes in VIDA and it passed the MOT emissions with no problem. The misfire seems to be there only when cold, seems fine when hot.
There IS a problem with the DPF clogging but that may be caused by this problem, not the other way around?
The swirl mechanism was broken so I have replaced that and cleaned the EGR.
VIDA only says possible source is 'Internal fault in ECM' but as I say the clone is the same.
Where do I go next?
Cheers

you need to fit a new Loom connector to the injector , You have started at the wrong end of the chain ...
first item should have been connector , second the injector and third ECU ( ECU is always very last on the list )
Two of these 30765319
you will need a very thin tool/screwdriver to release the terminals from the housing .
