Black/Grayish Smoke from 1.4 D4D

[Egis123]

Hello,

My urban cruiser 2010 1.4 D4D recently started to emit black/grayish smoke from exhaust. When driving normally there is no smoke but going above 2.5K Rpm and fully accelerating then it starts to emit and keeps emiting untill i let go. 

I have figured out that driving aggressively for some minutes will eventually come to a point where no smoke will come out whatever i do.

On the other hand driving below 1.7K rpm constantly for some minutes no smoke will come out but the first moment i accelerate hard it will emit insane amounts of black/grayish smoke to the point where it makes like a big cloud.

I also see no significant change in fuel consumption or any power loss.

The car has its particulate filter removed some time ago.

I did all the cleaning, and egr check but everything seems fine. 

What can i do?

Regards

Hah, reminds me of my dad's old TDCI Focus - He'd usually only drive it on very short journeys, so short he'd sometimes get as low as 130 miles out of a tank  

One time I borrowed it and when I got to the on-ramp onto the M25 and floored it, a massive plume of soot blasted out the exhaust - Must have scared the bejeezus out of the guy behind me  

 

It does sound like there is soot building up in yours for some reason, and then getting blasted out when you accelerate harder. Need to narrow it down - Could be bad fuel, variable turbo vanes stuck, partly clogged injectors, hardened soot obstructions in the exhaust, faulty/blocked EGR...

I'd try running a few tanks of Shell V-Power diesel or equivalent (Or some fuel system cleaner like Redex or BG244) through it first to see if that makes any difference...
