Hello guys,
can u help me out please? I would like to know if pump could be dead. My neighbour asked me if I could check lights on dashboard. First issue was NOx sensor which I replaced and nox error (efficiency too low) disappeared, but AdBlue failure message on dashboard stayed (no vcds error). After few test drives, this error came up:
Is pump dead or issue is somewhere else? I want to drop Adblue tank to check wiring and components.
I have checked replacement for pump: #561 198 969. I didnt find any leaks so I suppose that pump is responsible for this.
Thanks in advance
