Warning message came on for AdBlue system check. No problem, but had to add Adblue solution. Next time I know to buy and add myself. Instead paying dealer $153 to do it. I thought they would drain and add Adblue. They just added adblue solution. I could have done that myself. I read that dealer adblue service should drain and add adblue solution. Residual adblue solution could crystalize overtime.
