My Scorpio turbo 2.6 crde car automatically fail and display the check sybol on meter

The turbo uses a completely different air flow meter than the non-turbo.

SOURCE: I need a wring diagram for Scorpio CRDe 2WD

Wiring diagrams are coptrighted material. They cannot be posted here. Also, you evidently do not know what you are asking because most wiring diagrams for modern vehicles consist of several hundred pages. I would recommend checking with an online sevice information provider like alldatadiy.com or go through the vehicle's authorized dealer to obtain a service manual.

Hi
Turbo cars do drag some oily residue through the inlet system and, if the hose seals are worn, wil drip oil. This is all ok..just clean up the hoses and fit new seals. Make sure you always flush engine oil and use a new oil filter with the CORRECT engine oil.
If the airways are not correctly serviced, air mass meters, sensors, throttle body, egr will all get clogged up.
Regular service saves money.
Cheers
