What is AdBlue and why deactivate* it?

No malfunctions, no annoying refilling of the AdBlue system and additional costs, all this could be saved by deactivating the AdBlue system.

AdBlue, also known as Diesel Exhaust Fluid (DEF), is a non-toxic liquid used in many diesel vehicles to reduce emissions of nitrogen oxides (NOx). It consists of 32.5% urea and 67.5% demineralized water.

AdBlue is stored in a separate tank in the vehicle and is injected into the exhaust stream before the gases pass through the catalytic converter.

How does the AdBlue system work?

When the exhaust gases reach the catalytic converter, a small amount of AdBlue is injected into the exhaust stream.

AdBlue reacts with the hot exhaust gases and decomposes into ammonia.

The ammonia then reacts with the nitrogen oxides (NO and NO2) in the exhaust gases, converting them into nitrogen (N2) and water (H2O), both of which are harmless and naturally occurring gases.

Why actually deactivate* it?

  1. Cost savings: AdBlue is an additional ongoing cost for vehicle maintenance, as the fluid needs to be refilled regularly. Some people might attempt to avoid these costs by deactivating the AdBlue system.

  2. Avoid complications: The AdBlue system can be prone to certain mechanical problems, especially if it is not properly maintained. For example, it can become clogged or the system can freeze when temperatures are very low. Deactivating the system could avoid such problems.

  3. Performance improvement: In some cases, deactivating the AdBlue system could lead to an improvement in engine performance or fuel consumption, although the actual effects are often minor and outweighed by the negative environmental impacts.
  4. Convenience: AdBlue tanks need to be refilled regularly. Deactivating the system eliminates this maintenance requirement.

AdBlue systems can sometimes malfunction, requiring expensive repairs. Deactivating the system could be an option to avoid these costs.
