Hi all
Iv'e been hovering about in the back ground for a little while now, so maybe its about time I attempted my first post.
I have read Sir Sams very informative getting started guide and worked through some of the basics on my UK spec 2004 2.5 CRD.
Changed the oil and oil filter, changed the air filter, changed the fuel filter about 12 months back, checked over the intake hoses which seem ok and cleaned the MAP sensor. I was looking forward to performing the ORM trick but I just cant find a MAF sensor anywhere on either the filter box or intake pipe. Just wondered if anyone might know if or where the sensor may be located.
The 2.5 CRD does not have a mass airflow sensor.....I have a 2002 2.5 CRD.
The nice thing about our models is that it is easy to disable the EGR....without generating any codes.
You see the small black plastic cylinder sitting in front of the airfilter and behind the washer bottle? It has a small clear paper filter dropping out below it, has two small rubber pipes plugged on it and has a connector on it. This is the EGR solenoid for the 2.5 CRD. You can block off the pipes which will then stop the EGR working...the best way is to pull off one of the pipes and screw a small self-tapping screw into the plastic hole then replace the pipe to cover the screw.
The ECU on the 2.5 CRD does not check if the EGR has been disabled...it only senses current through the solenoid so if you do not unplug the connector...you will get no codes generated.
