DEF Systems Can Now Be Disabled if they Fail

Most that I go to have one as well. It’s a loss of deposit or booked stay.

Basically once money paid, it doesn’t come back.

Most I’m familiar with set parameters. The deposit is like earnest money in a real estate transaction. It means you have skin in the game. Otherwise you have situations like many State Parks encounter. An RV’er books several campsites, when they arrive they pick the one they like and cancel the others. In the interim, those sites are shown as reserved to other campers looking to make a reservation and likely go unoccupied for a time.

There are countless reasons someone may want to cancel, and most parks I know do their best to work fairly with guests. But when you commit to a site and the park takes it off the market for you, that site becomes yours. Expecting the park to absorb the cost of circumstances beyond their control isn’t reasonable.

Philosophically, I agree with the use of DEF to reduce atmospheric pollution. My issue is sensor failures that can leave you stranded on the side of a busy interstate highway. I’d be perfectly happy with DEF if I just filled the tank when empty and didn’t have to worry about sensors making sure input in the right stuff, right temp, etc.

I applaud the policy change and hope it will allow reprogramming our systems to disregard DEF temp, concentration levels, etc, and not derate our engines. In the meantime, I’ll keep my emulator close at hand and hope my (second) DEF head keeps working as I’m now out of the warranty window.
