Best practices with DEF handling will solve most of your problems.

DEF gets a bad rap.

-DEF itself is a cost to a fleet or truck owner.

-DPF filters are extremely expensive to repair.

-More tech in the engine = more engine codes.

These are all valid points but lets face it…Its good at what it does and its not going away in fact, the usage will double in the next few years as newer trucks are calling for a high DEF burn ratio.

At the end of the day we should all want cleaner air.

Best practices with DEF handling will solve most of your problems.

When we get a client complaint for a “bad def code” we go and the first thing we do is sample the DEF’s Urea content. Assuming it meets spec of 31.8%-33.2% Urea content the next thing we do is look at the environment around the tank and the methods of filling the trucks. 99% of the time when we show up it looks something like this…

A high dust or very dirt environment.

Look at the nozzle, it is literally sitting in dust. All it would take is one of those dirt particles to get into your DEF injector filter and you’ll lose proper flow of DEF.

This is all it will take to throw a “bad DEF sensor” Another issue we see is people filling old jugs with the pump we provide. Well, these old jugs tip over and get sediment on the tips and cause the same issues. DEF needs to be handle in a sterile manner.
