    Hi guys

    Audi A6 B6 2.0 tdi. I'm using 01 engine, 03 output tests.

    I'm testing the egr valve. When I active it it only opens a little bit. I was expecting it to fully open 90 degree's, but no.

    I got a brand new EGR valve and repeated this test, and again the brand new one only opens a little bit when activated by vcds.

    Is it normal for this test (engine off btw) for the egr valve to only partially open?
