Def Light Comes On Here S What You Should Do Obd Advisor Once you’ve purchased a car that requires diesel exhaust fluid, the first thing you should do is open up the owner’s manual and find out what will happen if the def light illuminates because you’re running low. emissions regulations in the u.s. don’t allow diesel vehicles to operate in the absence of def if it’s required by their. Def warning light what does it mean and why you should heed it's warningthanks to diesel exhaust fluid (def), you can drive your diesel vehicle with limited.
Diesel Exhaust Fluid Warning Light What Does It Mean An Low diesel exhaust fluid levels will cause the def light to start blinking. in most cases, it reminds you to refill the def tank. however, seepage, faulty connectors, and damage can lead to leaks in the diesel exhaust fluid system. a major leak can deplete the fluid reservoir to critically low levels, triggering the def warning light. Reset the exhaust fluid system. get a working scan tool that can reset a def system and plug it into the scan port beneath the dashboard on the driver’s side. turn on the scanner and navigate to “module setup.”. then, go to “reductant fluid.”. thereafter, move to “tank level reset” and reset the system. One of the most common causes of the def warning light is low def levels. def (diesel exhaust fluid) is a crucial component in the selective catalytic reduction (scr) system that reduces harmful emissions in diesel engines. if the def levels are low, the scr system won’t function properly, and the def warning light will illuminate. Get started. the diesel exhaust fluid (def) light, also known as the “adblue” light, is a warning light that can appear on the dashboard of many diesel vehicles. this light typically illuminates when there is a problem with the def system, which is responsible for reducing emissions of nitrogen oxides (nox) in diesel engines.

Def is a solution (or mixture) of 32.5% urea and 67.5% de ionised water. the solution is injected in the stream of hot exhaust gases and is carried to the scr catalyst, where it chemically reacts with its surface material and nox. the result is remarkable; def breaks down nox to h 2 o (water), co 2 (carbon dioxide) and n 2 (nitrogen).
