Problems with Kia Sorento

Hello everyone
!!! I have also noticed that it is consuming more fuel. I made an oil change, air filter, diesel filter and oil filter. The air flow sensor was also cleaned, however it remains the same. The turbo is heard that comes into operation, but without force !!! I would appreciate if anyone can advise me that anything else review ??? Thanks and greetings

Check the vehicle compression pressure. This is done with a compresimeter for diesel engines.
This must round 29.4 bar.
The other because it can smoke you is due to dirty injectors.

Luck

Thank you very much for your recommendation Guillermo ... I'm going to see that and I tell you how we are going ... greetings

Check the intercooleer sleeves, and the West Gate Electrovalvula to see if it works because that can cause you the smoke sees the air filter too, if you do not scan it to see what the machine tells you Remember that if the sensor is damaged or out of range sometimes cleaning it you do not do anything.-
