I blanked off the solenoid which is the central one of the 3 that supplies the egr valve.
Having read some of the problems that some guys on here, and other forums, have had with egr systems
made me think that they're just not worth it. Most manufacturers systems have at some time or other
have caused nothing but problems in cars driveability, particularly Mondeo diesels, with major smoking etc.
My previous D8 td suffered fopr a spell doing this and a problem was solved along with the fast idle problems that occurred.
As I spend most of my time at low revs, low gears and part throttle conditions then the egr valve is, for me, no good!
It really does help driveability and smoothness and gives a little but noticeable improvement in low end power as more oxygen is getting into the engine..not exhaust fumes.
Green is substitute pipe..blanked.
Blue arrow is original solenoid pipe to egr supply. This can be reconnected at any time.
Red to blank off the solenoid and ensure vacuum stability for the other needs of the system.
The trick is to ensure in all cases that you keep the system 'vacuum tight' as the supply of this serves thing like brake servoes..and in our case the turbo wastegate actuator which is where I believe/hope the issues that were having originate from.
