Hi everyone having only sat and read posts for some time i am now looking for some help as i have seen similar posts with nothing resolved . I have been finding that my d3 tends to thump from 3-4 and has given me fault code po783 as you would expect but today it bought on a transmission fault and limited gears on dash .
I also have fault codes po 405 po 404 and p1335 however the egrs have been blanked off . the other code on engine is po2a6 cyl 4 fuel trim , i am wondering if this is talking to gearbox ecu and causing fault . Did try to drive in manual side and then bought on code po730 . I have my suspicions as to what it may be but any help would be welcome , as my faith in main agents is well lets say limited . Car has covered 103k and recently had cambelt . 
Forgot to mention just before it bumps the revs rise slightly .

After clearing codes we found that on taking it down the road we got differant injector faults , so deduced that this could be DIRTY MAF OR MAP SENSOR on taking out the map sensor we found it to be caked in carbon , never a good sign so this was cleaned and put back in , we then removed the MAF and found this to be also in a filthy state . On test drive it smoothed engine out and no reaccuring fault codes . Still have a slight rise in revs before changing from 3-4 gear which it does in both manual and auto modes .
