What happens when you put water into your urea bottle? Just curious, I mean of course it will increase exhaust fumes and particulate matter, but would the vehicle know the difference, and would it actually hurt the diesel engine to do this?

I'm thinking that even if it's a crime I'm not going to get locked into safe mode due to a shortage like this, and will do just about anything to get around it temporarily like millions of others would.

Newer diesels like my Duramax will detect it and still enable limp mode.

“What happens when you put water into your urea bottle?”

Similar to upstream/downstream O2 sensors in a Gas engine, the SCR system has two temp sensors, pre and post DEF injector. Two pressure sensors, pre and post particulate filter. Then finally the DEF injector itself. Any of which failing or “being out of expected values” causes the system to fail.

These value will only be within parameters with the proper mixture of DEF.

Just dilute it

Also pee in the bottle....Urine is high in urea.

Bottles of urine litter the interstate freeways.....free supply.
