My car began developing this fault around 2 weeks ago but it has steadily got worse. Car is fine around town i.e 30-40mph low revs. On acceleration there is reduced power and lots (i mean loads!!) of black smoke from the exsaust, crusing at A road/ motorway speed (1800-2200rpm) the car judders as if the revs are surging and again any accelerationg produces black smoke but the juddering does stop.
Finally decided I had to do something about it, so had a quick google search found a few common problems. Straight away I found that the intercooler hose had a 1" split in it. So as I was going to have to take the undertray off and get the car on axle stands I deicded a quick service would be a good plan. I also read that sometimes an old fuel filter could cause similar problems. So I replaced the hose, changed the oil and filter, air filter and fuel filter. As I had the hose off I decided to give the EGR a quick clean. It wasn't as bad as some photos I had seen so I assumed that the EGR itself wasn't clogged and as I couldn't test it I have assumed it is all working correctly (Could it be a faulty EGR?). Put everything back together. Got the car running. Rev'd it up and still loads of black smoke from about 2200 rpm upwards.
For me next thing to check/clean is going to be the MAF but does that sound like it could be causeing all my problems? I am assuming I am not unlucky enough to have a 2nd split in any of the other hoses, dose seem a bit unlikly to me but no impossible.
Any other ideas where I should look next?

Yeah I have had the EGR off but it wasn't too bad I did give it a clean anyway. The problem I'm having is as I go through eliminating things I'm told it couldn't have been that by other people, so far the list of possibles:
EGR (cleaned but not tested) I also assumed my car was new enough to have the modified EGR.
Intercool pipe (replaced)
Fuel Filter (changed)
Injectors (I did think if the injectors where the issue I would get a miss, but it runs fine just ideling)
I think to be fair I'm at my limit of what I can work out. I still have some warrenty on the car so it seems time maybe to give up and send it to garage.

did you get to the bottom of what it was,as i have posted that i bought a mondeo,with what was supposed to be a us turbo,my mate turned off the fault but never got the code as his tool wouldnt tell him.
but i am having exactly what you are stating.

just a quick update to both this posting my own posting and anyone who is having the same problems.
CHECK the Hose from the intercooler to the EGR,
as mine had a split in it,once i had replaced this at a cost of £50.00, The car is running perfectly..
