Well, looks like I will need to take the truck in for its first warranty issue.

I have about 2200 km on the truck since I filled up the DEF tank and the gauge still shows full.

It is one of the irritating issues that plague some new trucks.

I hope I don’t get the run around by the local,stealer ship.

Not sure which one I will take it to.

Abbotsford Chrysler has never impressed my much.That leaves Chilliwack or Mission..

Likely it’s just stuck as I filled it to the brim...

I have the same truck as you and have 750 miles on it so far and I am just a tick below full.  I haven't filled it yet.

I read they don't use much until there is a big issue, then they drain that tank fast.

Steve, I'm sure it'll be under warranty so hopefully they don't give you a hard time. I don't know about the fluid level sending unit but my Dad's DEF tank in his Ecodiesel threw a check engine light for some sensor in the DEF tank. They said the sensor is not replaceable so they had to get a whole new tank at the cost of $950+. Thankfully it was covered under warranty.

I dragged out my journal today to check my mileage and fluid consumption.

It turns out I have driven 1410 km since topping up DEF. I topped up both DEF and fuel this morning and reset trip odometers.

I will use trip A for fuel and trip B for DEF.

I only put in  3 liters of DEF to fill that tank.

reports are around 1600 miles to a US gallon of DEF consumption,so I might be ok.

Any harm if DEF tank run/out  dry ?

Check engine light, limp mode and even shut down if DEF goes dry. messages/chimes are hard to ignore. 

 

I could be wrong but the DEF tank is tiny

maybe 4 gallons?

Unless you are working the engine hard, these trucks sip DEF.

I usually don’t work my trucks hard unless towing hills... Then they earn their worth.. In a careful way of course😇

I was never able to put more than 4 gallons in mine so there must be a gallon left and I bet once it gets near the bottom, you will see the warning msg, limp mode etc

 

I had the warning msg once, couldn’t get anymore than 4 gallons in.

You can buy oversized DEF tanks from Titan tanks. I never found a need for it. Eventually it was disabled when all the other emissions crap failed. 88,000 miles, all highway and I kept getting msgs about the dpf 90% full.

Warranty on that stuff was 80,000 miles.

Spend 7-8k to replace it all or spend 2k to delete...stuff fell off.

Gary, I don't think that will work as the fuel tank on the cab-chassis are aft of the rear axle which would allow space where the pickup fuel tank sits to allow a larger DEF tank on the cab-chassis.

On an average round trip to Alberta of 1800 miles I only burn 6 to 8 gallons of DEF with the Kenworth T680.
The Ram trucks are way less obviously.. Surprised how little DEF the big Pacar engine burns..

When the exhaust systems are working properly the consumption is minimal but when something goes wrong they suck that tank dry in a hurry.

 

I think it looks like on the guage of the 70's Era Camaro gas gauges on acceleration. LOL
