Hello All,
I have a yellow adblue with a spanner logo, car flashes a messages that says AdBlue Error! it does not stay on for long maybe a few seconds.
I dropped the car off at the dealer yesterday for an oil change and a diagnostic for the check engine light, they have replaced the Coolant pump under warranty but they said the other codes are caused by an interrupted regen which is not covered.
From googling these codes point to a issue with the Adblue system not the DPF.
Has anyone else had these codes?
Here is my vagcom errors -
