The AdBlue error appears on Euro 6 diesels with SCR and often causes power reduction and a start countdown ("remaining starts: X"). Ignoring it can prevent the vehicle from starting.
Symptoms
- "AdBlue error" / "Check AdBlue" message
- Remaining-starts countdown
- Power reduction (limp mode)
- Engine warning light on
Common causes
- Faulty AdBlue sensor or pump
- SCR injector clogged by urea crystals
- Poor AdBlue quality or frozen tank
- SCR ECU software errors
