Contaminated def fluid ????

[paulm85]

Ok guys I was on the way to the farm at 5 or so this morning and I'll b damned if I didn't get a message saying "contaminated def fluid truck will be limited to 55mph in 200 miles"

I was wondering if anyone else has had this happen?

We use a 55 gal drum of def that is approved by all manufacturers in both my truck and my dads and we have pulled out of the same barrel for many thousands of miles on each truck.

I will call the dealer tomorrow but I just thought if anyone had that happen they could share what's goin on.

Truck has 18000 trouble free miles so far
Thanks

I know that stuff does have a shelf life not sure how long you been using that drum.

[paulm85]

I think we got it in November or December last year.

I thought I read somewhere it's good for a year I guess there's different varibles could come in play such as storage temp. Hope it gets worked out

Did you leave it where water could seep or drip in?

[paulm85]

Nope its a sealed drum in a climate controlled shop here at the farm.

I haven't put any in my truck for maybe a couple thousand miles so I wouldn't have thought there would be a way for new contaminants to get in all of a sudden.

Were trying to finish up planting beans so I may not get it to the dealer right away but I'll let ya'll know what ended up happening.

Ive got the same issue. Came on this morning. My truck has 1600km on it and the contaminated DEF message came on. Never filled it let alone opened the cap

[paulm85]

Wow. Now I don't feel so bad I guess. You get the same message about 200 miles then max speed 55 mph too?

[AlbertaStroker]

Yup. Just in kilometers. 300km and 88km/h

Finally got the truck back after 2 and a half weeks.


Turns out that it was a Nox sensor.....not exactly sure what that is but that is what they told me caused it.
