if its black will likely be mucky egr or boost pipe seal gone, could also be a dpf issue.
if its white its generally fuel related

Look for oil in the inlet pipe from the rocker box vent to the - heat exchanger - inlet pipe to manifold - Manifold is likely gunged up. Exhaust and oil = gunge.
Engine heats up takes and hour or so and the inlet system gets hot enough to evaporate some of the oil/gunge which gets burnt = grey/black smoke. Clean out the inlet system.
White/grey/black smoke.
The 2.4 transit I had gave off black smoke when going up hill around a corner in second gear with the rpm up - the system was well heated up, after a few mins and on the flat (less effort) the black smoke stopped.
DPF blocked. Diesel is used to burn off the soot. White /grey smoke - can be mixed with gunge can be black.
Forscan helps to know what it is about - can show soot % content.
White smoke - coolant loss - check coolant bottle for bubbles - pipes soft/hard - if hard = head gasket blown.
If coolant bottle has black areas = oil in coolant - from oil cooler.
White grey smoke - coolant loss, damp in exhaust, very high ambient humidity, unburnt fuel, coolant mixed with gunge.
What is seen (smoke) can be a combination of the above - water, fuel, vaporised gunge.

I believe he's talking about the intercooler, it's a heat exchanger of sorts....not commonly known as that though.

Related info' like hen's teeth.
The smoke in your image is the same as mine was at times ( when it seemed better ).
Went through the smoke no smoke black and grey and white and DPF, coolant problems etc etc.
On one occasion it smoked for 30 mins could not see the road behind.
Used a colour test on the coolant = gas in the coolant - later could see bubbles in the coolant at cold start.
Engine out and found the block and head faces were corroded, the head gasket pitted and passages blocked.
So recon' engine put in. £3500 +. Did it myself. So on top of the 3500 there are garage charges. On top of the 3500 DIY are the tools etc etc etc needed to do the job.
On the 2005 Iveco 2.3 the glow plugs in the cylinders operate at below ambient 5 C.
Transit E5 it seems there are the 4 cylinder glow plugs and another glow plug/heater which is on the fuel supply to the injector/vaporiser with the DPF system.
There can be different things on different vans of about the same year(s). I have not found info' which is specific to the van I have nor have found info' specific to what is on it.
1 It seems that your DPF is partially blocked. 2 There is a coolant leak. 3 There is oil/gunge in the air intake system. 4 The EGR is stuck open. Could be all or them - you fix one you become aware of whatever else is wrong.
2,3,4 could look like/cause a problem with the DPF.
