Volkswagen Bora - Fuel consumption - karak

Hi folks!

My car is a vw bora 1.9 tdi pd 130.
The problem is now...I think the fuel consumption increased.
Symptons were:
Limp mode,power loss,17965 error code in vag-com which is Charge Pressure Control: Positive Deviation

I have changed n75,maf,cleaned the turbo with innotec turbocleaner.
Now the problem:
Since a mechanicer has cleaned the turbo,I get 30mpg consumption,and a few black smoke-on water(more water) on the floor If I get 3000-3500rpm in idle.

The question is:

Can a sticky turbo vanes or bad MAP sensor cause this symptons?
I mean the increased fuel consumption and the bit black smoke.

The weird thing is when I get first time limp mode,there was not black smoke or increased fuel consumption.I have just realised since the turbo has been cleaned with innotec cleaner.

Other idea is this stuff which comes out from the exhaust still can be the innotec cleaning stuff?I have driven about 100 miles since has been cleaned.


I have got this with vag-com:

Volkswagen Bora - Fuel consumption - karak

Please someone help me out :( ....

I don`t know why is my car using to much fuel...If it can be sticky turbo vanes I am going to recondition it,because it lost power and goes to limp mode as well.

Volkswagen Bora - Fuel consumption - karak

I`ve got 23.6mpg avarage :/ ...........

Other thing:

Can a leaking exhaust causing this fuel consumption?

My mechanicer said when he cleaned the turbo.one of the stud at the exhaust has broken,

but he just put it back,and now only two studs holds the exhaust to the turbo.

I can not hear any noise.
