1 – What causes the Adblue light to illuminate?
The Adblue light in your vehicle can come on due to various reasons, primarily associated with a malfunction in the exhaust gas after-treatment system or its components.
Frequently, the Adblue warning light indicates that the Adblue level is low, prompting you to refuel. Sometimes, the dashboard might display the remaining kilometres before the vehicle cannot be restarted or enter limp mode. However, in more concerning cases, a faulty element in the Selective Catalytic Reduction (SCR) system can be the culprit, potentially leading to higher repair costs.
2 – Reasons behind the Adblue warning light on the dashboard.
As previously mentioned, the reasons for the Adblue warning light are diverse. Common issues include faulty NOx sensors, malfunctioning Adblue injectors, defective Adblue pumps, faulty fuel gauges, or malfunctioning of the exhaust gas post-treatment control module. The cost of repairs varies depending on factors such as system complexity and the vehicle model.
3 – Consequences of an active Adblue warning light.
The consequences of an active Adblue warning light depend on the vehicle type and applicable regulations. For most trucks, the warning light restricts engine torque. After a certain duration of operation, the vehicle may enter “Limp Mode,” which limits speed to around 20 km/h in many cases.
4 – How to resolve the Adblue warning light issue?
There are several ways to address the Adblue warning light:
- Refill the Adblue tank.
- Replace the malfunctioning components, such as sensors, injectors, pumps, electronic modules, etc.
- Reprogram the system to operate without Adblue.
