However, let’s see how the exhaust fluid system works to appreciate it better. This is because running on a low DEF fluid level can affect the vehicle’s engine as much as a low engine oil level can also impact an engine. The fluid is as important as other fluids in a vehicle. The system works with diesel exhaust fluid, popularly known as DEF. This is common with diesel-powered truck engines.

The exhaust fluid system is responsible for minimizing the emissions of nitrous oxide (NOx), enabling a vehicle to meet the emissions regulations standard. Besides the EGR (exhaust gas recirculation) system and DPF – diesel particulate filter, the exhaust fluid system is also designed to enhance a vehicle’s ability to operate proper emission. Several systems have been built in various vehicles to enable car owners to overcome emission regulations. However, not to worry! This article explains what the exhaust fluid system and the warning light mean, as well as the solution to the problem if it ever occurs in your vehicle. Therefore, you must find a way out as soon as possible. Running out of this fluid or experiencing the system warning message is not good for your engine. The system is designed to run on DEF fluid which is subject to exhaustion.

Meeting emission regulations standard in diesel engines is hardly possible without a properly functioning exhaust fluid system hence, the service exhaust fluid system warning signal requires immediate attention if you suddenly discover it on your truck.
