Frequently asked questions
What causes a DEF quality fault?
Diluted, contaminated, or wrong fluid in the DEF tank. Even topping off with water or old DEF can set it. We test concentration with a refractometer.
What if I put the wrong fluid in the DEF tank?
Do not drive far. We drain and flush the tank and lines, refill with fresh DEF, and clear the fault before the wrong fluid damages the pump or injector.
How is DEF quality tested?
We use a refractometer to measure urea concentration, which should be about 32.5 percent. Readings outside range confirm contamination or dilution.
Will a flush fix the no-start countdown?
If bad DEF caused the fault, flushing and refilling with correct fluid clears the quality code and the countdown. We verify the SCR reads correctly after.
