Lack of power Hyundai Santa Fe 2008 CRDI

Hello friends I have a Santa Fe 2008, and I have power problems, it stays at the exits when waiting for the green light in the semaphors in addition to an excess of fuel consumption. He was taken technical service and have had all the engine electronics and transmission and have not encountered problems, so they determined to disassemble the turbo to review due to a strange noise.
Do you have an experience in this type of failure?
Grateful for your comments ....

Hello friend and have you not given you the turbo? Does it make you a lot of smoke?

I still do not have the result of the turbo stat

Hello friend, I had a similar problem we did the check and the result came out that the air flow sensor must be replaced.

Thank you very much for your Kuhner help, I will try with the car sensor of a friend, to compare the result.
Later I tell you ...
