egr valve
i dont get this. if its better to block off the egr, then why would you even bother cleaning the soot that is blocking it? wouldnt it work just the same?
|
If the soot is blocking the EGR then it is also likely blocking some of the intake passages as well. Cleaning it out and then making a block-off plate cures the problem permanently. RT
|
on mine the only thing that looked blocked was the hole where the egr mounts was the only thing that looked really sooted. but then again i probably should pull the manifold and soak it in my parts washer full of diesel. i just need to get the gasket. does it perform any better with the egr functioning
|
Performance is generaly better with it NOT functioning. And it's the crud you can't see that is bad. It's a stupid thing to have on a diesel, VW is haveing trouble with it to this day.

then why dont they make it legle to take off

Because, while it works, it lowers Nox in the exhaust, one of the few things diesel is high on the polution scale with. Thank you EPA.. :rolleyes:
