Bought 2 large containers of adblue from the stealership and filled up the tank. I read on the forums (this and others) that either the sensor would reset itself or I could perform a hard reset by turning the ignition ti run for 20 seconds to a minute. Neither of these techniques has worked so I have two questions. So I'm driving 280 miles filling my def before I left for trip of course same warning comes on, go to the dealership about 40 miles later. The dealership tells me bad def drain and refill 400. Oh and there's a update software. Me how when I use vw only def. Just due the update. 80 miles later the light goes out and never a problem again.
