I was also able to see the egr work when you cruise in 2nd or 3rd gear at a high rpm.

As I expected though, through normal driving when I always coast in 5th gear I never saw vacuum on the egr, leading me to believe that the EGR rarely is used on the d15z1.
Wow Steffen Excellent work !! I fixed the leak on the egr valve on my vx and I will now go through the tests in the manual to make sure the system tests out. Then I will drive like in your example and we will see if a totally stock vx does the same thing.

Maybe someone else with a vx could do it also. Hx might be different but would still be cool to know if leanburn cruise uses ANY egr at all.
