The rear washer fluid stopped working on my Evoque. Before I take it to the dealer I just wanted to be sure I'm not completely missing something. On other vehicles I've had, there was a separate tank for the rear washer fluid. I don't see one on the Evoque. The owner's manual only references the one in the front in the engine bay. I checked and its definitely full. My front washer nozzles work fine but the rear isn't working. Has anyone else had this happen?
