Hi,
Having a problem with the ADblue warning system. Warning light activated in June 2023 and taken to dealer to fix as sensor was showing a PP2200 and U029D fault. The replaced a sensor and topped up with 10 litres of Adblue. The car has done 6K miles since then and adblue light has reappeared. I have taken back to dealer as I believe sensor is under warranty from original fault. They have said it how has fault P20EE and tell me this is not covered under warranty.
Are dealership trying it on or is this a genuinely different fault?
This is a 2016 model.
Thanks
Joe
