Update:
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.
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
