OBD2

[ex Flying Dutchman]

Hello: I have to reset the message about def quality.
I had this last year directly after fuelling, just now I have it again.
Last year we stopped close to a dealer, as there are only 4 in Mexico, but that was in the middle of the cartel unrest. Now we are close to a dealer, 3 hrs away, but that will be a large cost.
All the dealer did last year was a reset.
I would like to buy an obd2 reader which can reset this.
Apparently a KINGBOLEN K7 can do it, but are there cheaper options?

Desperate, as we cannot have the car break down in the middle of no where

As we are in the middle of nowhere in Mexico, I bought the Kingbolen K7 scanner when we got the dreaded warning last week. It took a little, but it reset everything. (U$400)
Info on youtube for procedure.
If the problem comes back, at least we can reset and make it to civilization
tip: make sure ignition is off before it asks to turn it on.
