Per VW Technical Bulletin for this fault code, there was a faulty weld at the reductant line connector to the supply line causing leakage at the reductant injector. The proposed fix is to replace the DEF supply line input line, part [561 131 984 D]. However, the diagram on the VW Parts website is terrible. Is there a better diagram available for a do-it-yourself mechanic?
