Hi I have a 2016 2008. Yesterday my engine fault, UREA and adblue lights came on. The car was serviced in June and adblue was added. I took it back to my garage and they checked it and said that the valve is stuck closed and I need to bring it back to the dealer. The fuel tank may have to be replaced. They said it was a peugeot manufacturing issue. Before I contact the dealer does anyone have any similar experience and can I argue that its a Peugeot fault? Thanks!
