Subject: RE: Anyone replace DEF with water? Water won't hurt the system but it will de-rate you pretty quick. ECM compares NOx values pre/post, if conversion is low it will start throwing codes and will eventually derate.
Can we use water instead of DEF?
If you remove the urea from the DEF -- that is, if you run water through the injectors instead -- it probably won't hurt anything, since you're reducing the level and quantity of corrosive reactants inside the stainless steel SCR system.
Can you run a diesel without DEF?
Can You Run A Diesel Engine Without Def? There is no way modern trucks will run without DEF. Drivers of diesel trucks therefore need to check their fluid levels frequently in order to make sure they're as good as possible. It is everyone's responsibility to reduce emissions.
Can you replace DEF with pee?
DEF and urine are not interchangeable, and if you do decide to pee in your DEF tank, you could be facing some hefty repair bills. Because of the other compounds found in urine, peeing in a DEF tank could ruin the filters and the whole SCR system if used too often.

Can you fill DEF while engine is running?
DEF is vaporized and decomposes into ammonia and carbon dioxide in the exhaust pipe. In order to ensure that owners take their clean-air responsibilities seriously, the Environmental Protection Agency requires manufacturers of new light-duty diesels to interrupt the normal startup routine when the DEF runs out.
Should I delete my DEF system?
The catch about a DEF system is that you have to keep its fluid reservoir filled regularly to keep it functioning properly. This doesn't just take time – it costs money, too. Deleting your DEF system can help save you money. Plus, your exhaust might have a bit of a beefier growl once you're done.

What is a Qls sensor?
The commercial vehicle industry is experiencing unprecedented supply shortages on some necessary components. One such component is the DEF Quality Level Sensor (QLS). Due to this shortage, trucks experiencing a QLS failure may not have a new sensor available for repair.
Where is the DEF level sensor?
A DEF quality sensor is mounted on the side of the DEF tank. This sensor detects the Urea concentration in the DEF to confirm it is acceptable for effective dosing (approximately 32.5% Urea).
How does a DEF quality sensor work?
The DEF level sensor, which is part of the DEF sending unit, measures the level of fluid remaining in the DEF tank. When the liquid level is low, the DEF level sensor sends a signal to the vehicle's ECU which then triggers the warning light on the gauges or panel.
Is there a shortage of Def fluid?
Diesel exhaust fluid is a critical component of every fuel program. Required since 2010 for on-road fleets and since 2015 for off-road fleets, most modern fleets require DEF to remain mobile. Yet a severe, worldwide shortage has spurred severe supply chain challenges.
