Hello all, I have the following problem at.mein v6 3.0 tdi bj 09. In the kombi stand engine fault, workshop. I read the error and there stand agr valve sporadically( N18). I cleaned the valve, which in my opinion was not even so trusty. Everything was built together again and when I start it now it runs completely quiet and clean but after 7 sec. it goes out abruptly! Error read out again, 0 error. Does anyone have an idea where the problem might lie here? Vi Elen Thank you Greetings
