Unraveling the Citroen Adblue and NOx Conundrum: A Comprehensive Guide
Introduction:
In the ever-evolving landscape of automotive technology, Citroen has consistently stood out for its commitment to innovation and environmental consciousness. However, like any sophisticated vehicle, Citroen models equipped with Adblue technology may encounter challenges related to NOx emissions. In this blog post, we’ll delve into the intricacies of Citroen Adblue and NOx issues, exploring the causes, implications, and potential solutions.
Understanding Adblue:
Adblue is a urea-based solution used in Selective Catalytic Reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions from diesel engines. Citroen, in line with global emission standards, has incorporated Adblue technology in its vehicles to minimise environmental impact and ensure compliance with stringent regulations.
Common NOx Issues:
- Adblue Quality and Quantity:The effectiveness of the SCR system depends on the quality and quantity of Adblue. Inaccurate levels or poor-quality Adblue can lead to suboptimal NOx reduction.
- Sensor Malfunctions:Citroen vehicles are equipped with sensors that monitor Adblue levels and injection rates. Sensor malfunctions can result in inaccurate readings, leading to improper Adblue injection and increased NOx emissions. This can lead to you spending hundreds on sensors which in the future will fail.
- Contaminated Adblue:Contaminants or impurities in the Adblue solution can compromise its effectiveness. Regularly using contaminated Adblue may cause damage to the SCR system and increase NOx emissions.
Experiencing AdBlue-related issues?
These faults are a problem with the following vehicles which include the 1.5HDI,1.6HDI and 2.0HDi engines.
Citroën: Berlingo, C3, C4, Grand-C4-Picasso, C5, Jumpy, Jumper, and Space tourer.
Possible Citroen system fault codes that are related to Adblue issues are:
- P2002 – the particulate filter is full.
- P1412 – particulate filter permeability – DPF.
- P20E8 – urea pressure ADBLUE – insufficient.
- P2BAD – ADBLUE system error – SCR.
- P20EE – ADBLUE system error – SCR.
AdBlue faults commonly lead to a non-start situation. If your Citroen car or van is immobilised or in limp mode with dashboard warning lights, our mobile AdBlue delete service is available to address the problem.
Why is my AdBlue light still on after filling?
Some possible causes could be:Â AdBlue tank sensor issue: The AdBlue tank sensor may not be working properly, causing the system to think that the tank is empty, even though it’s full. Costing hundreds of pounds to replace.
Addressing Adblue and NOx Issues:
During an AdBlue delete, we deactivate the AdBlue function in the ECU, occasionally requiring the disconnection of the AdBlue control module. This action eliminates warning lights, limp mode, or potential no-start conditions, providing a permanent solution for your Adblue and NOx issues. We offer Lifetime Guarantee with our solutions and cover the Berkshire and Oxfordshire areas.
This service is sold for off-road use.
