Hello guys, have my AGR valve tested by shutting down and found that it is defective. (AKQ, 1.4) Now I want to expand and renew it. Unfortunately, I don’t get the pipe that goes to the throttle valve from the AGR valve. I can release the nut but at some point the thread is over and the pipe is still in it. Is there a special trick? Do I have to use violence? Who has removed the thing before? Thank you
