156 2.4 jtd missfire/flatspot

Hi everyone a little help needed please. 2001, 156 JTD 2.4 with 135,000 miles it has full service history. I have had the car a week and it has developed a missfire/flatspot, it happens just under 2000rpm and then clears when you increase revs, its worse on an incline occasionally under acceleration it stutters then the engine management light flashes briefly then the cars runs fine. The car starts fine and revs freely and does not smoke. I have read through hundreds of posts and am now suffering from imformation overload. So my diagnosis would be dirty maf or sticking ecg does this sound right or am i looking at something else thanks for any help now and in the future.

Did you manage to get to the bottom of you problem as mine seems to have almost identical symptoms?

Same symptoms here, it only gets worse im afraid, my started every now and then, now pretty much happens every time i potter around doing 30 (especially at traffic lights!), i took egr off cleaned it out, this sorted it out for just over a week but now symptoms are back, thinking its gonna be a new egr valve or might try stripping selenoid down as i only wd40 outside of it last time. Surely it must be valve as it wouldnt have stopped for over a week otherwise????????
