hey Gaz, the adblue is giving me the nightmare on my imported X6, already burnt $1K with Continental BMW and still nothing is fixed and they insist I bring it back for more diagnostic so they can continue to work on the "process of elimination". They refuse to give me quote to replace the SCR injector and NOX sensors, which are the key components of adblue and could solve the problem. I would really appreciate any solution or recommendation to a reliable workshop in Auckland!
