DEF/SCR Delete
Familiarity with the world of truck maintenance and optimization often leads to the topic of operation and removal of SCR and DEF systems. And we have everything you need for that. Meet us!
The Mochester 4 application (M4 App) is the leader in the range of truck tuning solutions designed by an experienced team. Focused on key services such as deleting SCR, DEF, DPF and EGR on trucks, buses or CE the Mochester 4 has a distinctive feature - the fine-tuning options. You can pick up these options according to the truck’s chassis number or VIN by connecting the truck via a diagnostic adapter to your laptop with the previously installed M4 App. This ensures that every tuning solution matches your truck's specifications exactly.
Let's look at DEF/SCR systems’ work, as well as their advantages and disadvantages
SCR stands for Selective Catalytic Reduction, an essential component of modern trucks designed to reduce harmful emissions. This system uses a special liquid called DEF or AdBlue (diesel exhaust gas liquid), which splits emissions of NOx (nitrogen oxides) into harmless nitrogen and water vapor.
The principle of DEF reagent operation on trucks
DEF and AdBlue are two different names for the same substance used in SCR systems (Selective Catalytic Reduction) for cleaning exhaust gases from harmful emissions from trucks air purifiers with diesel engines.
DEF (AdBlue, Urea) is a special liquid consisting of water and urea (purified carbamide liquid) in certain proportions. Both types of substances contain urea in a concentration of about 32.5%, the main difference may be the content of impurities and the quality of the product, as well as the fact that DEF can also contain high degree of purification water.
The main function of DEF is to provide ammonia (NH3) for the chemical reaction in the SCR catalyst. DEF is injected directly into the exhaust stream before the SCR catalyst, where urea decomposes into ammonia and carbon dioxide
The SCR system principle of operation
The SCR is a catalyst that uses ammonia from DEF to convert nitrogen oxides (NOx) into harmless nitrogen (N2) and water (H2O). The main function of SCR is to conduct a chemical reaction between ammonia and nitrogen oxides in order to reduce their content in exhaust gases. The SCR is usually located after the oxidation catalyst in the exhaust system and requires for its operation the use of ammonia inflowing from the DEF.
Essentially, truck SCR delete is a tuning process where the SCR system is bypassed or removed. This is the case when our offers its SCR delete solution on the Mochester 4 App. We specialize in configuring truck software, developing our own firmware, configuration applications and adapters. Thanks to our vast experience, the best testers and global market presence, we have become a reliable partner for truck owners around the world.
Our SCR delete solution is designed specifically to improve the performance of your truck, bus or CE offering potential benefits such as improved fuel efficiency, increased power output and reduced maintenance costs. However, it is important to note that the SCR delete may not be legal in any jurisdictions, as it involves changing emission control systems. We always advise you to familiarize yourself with local regulations and consider the environmental impact before proceeding with such modifications.
Advantages of deleting the SCR system on trucks, buses or CE
- There is no need to use urea: One of the disadvantages of the SCR system is the mandatory use of a special liquid - urea (DEF, AdBlue), which must be refilled regularly to ensure the normal operation of the system.;
- No additional costs: The use of urea (DEF, AdBlue) also entails additional costs for its purchase and maintenance of stocks, which can increase the operating costs of vehicles;
- There are no potential problems with the quality of urea: The quality of urea (DEF, AdBlue) is crucial for the effective operation of the SCR system, therefore, the use of low-quality or fake urea can lead to reduced cleaning efficiency and damage to the SCR catalyst;
- Fuel saving: unlike some other NOx reduction methods, such as the EGR system, the SCR system does not have a significant impact on fuel consumption;
- If the urea level is insufficient (DEF, AdBlue), your truck simply will not start;
- Also, there is a frequent problem of liquid thickening (DEF, AdBlue), when operating in regions with low temperatures, which leads to the inability to operate your truck.
Disadvantages of deleting the SCR system
- Increase in NOx emissions: The main advantage of the SCR system is its ability to significantly reduce emissions of nitrogen oxides (NOx), which helps to reduce environmental pollution and improve air quality.
We strive to provide high-quality services that meet the needs of our customers while adhering to ethical standards. Regardless of whether you want to solve a specific problem with your truck SCR system or you are exploring ways to optimize its operation, our team is always ready to offer qualified recommendations and solutions.

Before setting up your equipment, review the type of adapter required for your truck using the "Check Available Services" section in the M4 app. Anticipate more control, compatibility, and convenience with VLOMINGO!
The frequency of DEF refills depends on various factors such as engine size, mileage, and load conditions. On average, trucks consume about 2-3% of DEF per gallon of diesel fuel. Typically, DEF tanks are designed to be refilled during regular maintenance intervals, but it's crucial to monitor levels regularly to avoid running out.
If your truck runs out of Diesel Exhaust Fluid (DEF), it can lead to reduced engine performance, emissions non-compliance, warning lights on the dashboard, incomplete regeneration of the diesel particulate filter (DPF), and potentially engine shutdown to prevent damage. Regularly monitoring and refilling the DEF tank is essential for maintaining your truck's performance and compliance with emissions regulations.
DEF is sensitive to temperature extremes, UV light, and contamination. It should be stored in a cool, dry place away from direct sunlight and sources of contamination. When handling DEF, use dedicated equipment and containers to prevent contamination. Additionally, avoid mixing old and new DEF, as it can affect its quality and performance.
