AdBlue Warning Light
The AdBlue warning light shows that the AdBlue tank is getting low or that the SCR system has a fault.
What is AdBlue Warning Light?
A countdown in kilometres often appears when the level is low. When the range reaches zero, many cars cannot be restarted. Faults in the heater, pump or NOx sensors can also trigger it. AdBlue is sold at most fuel stations and car parts shops.
How it works
The level sensor and SCR control unit monitor the fluid and the system, and legal rules require a warning and restart block.
Why it matters for your car
Top up with certified AdBlue in good time. A fault warning needs diagnosis even if the tank is full.
