Smoke Problem

[confused212]

HI All,
I’ve got a 2002 1.9 DCI with 71k on the clock.

Just had the intercool changed, turbo checked, EGR valve cleaned, turbo sensor replaced.

The main problem I’m having with the car is, I went to take the car out the other day and when I started it the serv light came on and when I put my foot on the accelerator the black smoke came out of the exhausts.

Would the limp mode problem that I’ve had for the past 3 months have caused this problem with all the stopping re-starting the engine bout a million times every time I take the car for a long journey.

Any help on the cure and possible cost to fix the problem / problems would be a massive help
