DEF Level - Gauge Messed Up?
 
So far granted it's been 3 days) my '14 CRD has been a joy to drive...but one thing has already popped up.

When I picked it up at the dealer they said they only had one, 2.5G jug, of DEF in the shop. The gauge was showing 50% and this brought it up to 80%. They said just to run it back by sometime to top it off. That was on Saturday.

I've been messing with the gauges while driving around for the last 180miles since then and on Saturday/Sunday it was showing 80% DEF.

Monday morning it was showing 100%. After work Monday it was showing 0% but not giving any other messages. I took it to the dealer and on re-start it was showing 100%.

This morning it is back to 0%.

Anyone else have anything strange happening.


The dealer was saying something about it maybe having sat at 1/2 a tank for awhile before delivery and the float sticking. I have my doubts because it's not giving me a "Low DEF" message when it goes to 0%. Basically the dealer's advice was to drive it for a couple of days and see what it does.

I picked up two jugs at Autozone last night (about $11/per 2.5gal) because I'm super busy this week and I'd have to hop on the interstate for about 10 miles to get to a truck stop that sells it in bulk from the pump. I didn't get around to it last night but I'm going to top it off tonight and see how much is really in there right now.

Just a note if you are a details oriented guy: There may be a shelf life of 12 months for the DEF fluid. You may have to look at the expiration date on the bottle. I doubt though that is significant at all.

I just topped it off - it took roughly 1gal.

I guess I'll watch the gauge and see what it does. I am going on a road trip this weekend so I'll be at 800-1000 miles by Sunday.

I topped off my DEF tank last night when I got home from work and the gauge did not move from the 1/4 tank it was previously showing. This morning on my way to work the gauge was still reading 1/4 full. About 10 minutes in to my drive to work it finally moved and now shows the DEF tank full. Is this normal??

I don't know if it's normal - but after my initial odd readings....


Mine went to full shortly after I filled it by hand with jugs.

I'm at about 1650miles now. It went to about 3/4 pretty fast...and now is getting close to half. Seems odd to me that it's showing it going down so fast.

Mixed city/highway, only some minimal light towing so far.

Over 2000 miles, and still at full. Wondering with the first builds if there was a crystal buildup from just sitting there. The crystals will dissolve when the tank is refilled full with fresh DEF. Have heard of a few leaks, but they would be easy to spot - just look for a buildup of white crystals under the rear of the Jeep. It sound like it was an isolated incident, but on the initial orders, the DEF tanks were installed in the parking lots just before release. Guessing the QC may have been down, as they were not installed on the factory floor. All new builds have the tanks installed on the production line.

Are you using the remote start feature? I read elsewhere on this forum that the DEF gauge shows 0% when the vehicle is remotely started. I have not yet tried to confirm it.

Re: DEF Level - Gauge Messed Up?
 
I'm experiencing some strange DEF gauge readings myself. I've had the vehicle for a week, and it left with a low DEF level (all I know is it wasn't full, and the dealer said they would top it off for me when I come in for my first service).

Today I looked at the gauge, and it was about 35%. So I added about 1.5 gallons, turned the car on, and saw it immediately increment up to about 50%. I figured I still had room, so I turned it off, added 1 gallon, and turned it on again. The gauge didn't move at all, just stayed at 50%.

I thought maybe it's the incline, or maybe it'll take some time, so I drove to the gas station and filled up some diesel, and drove back home. I didn't see the DEF reading change at all during that time. Since it changed so fast the first time, this didn't seem right.

I'm wondering if there's a problem with the DEF sensor, the EVIC gauge software, or the DEF tank.

Are there any signs I can look for that would indicate a DEF tank leak?

When DEF dries, it leaves clear crystals. If you have a leak, you should be able to crawl under the back of the Jeep (that is where the DEF tank is) and look for a line of white crystals. By the way, when you add DEF, you have to add a significant amount before you will see movement on the DEF gauge. Look at the owners manual, it will tell you more info.

Re: DEF Level - Gauge Messed Up?
 
Just a quick update, but 3 days after my DEF fluid addition, I noticed the gauge has now updated from 50% to 75%. Not sure when it actually registered the change, or why there was a delay. Maybe there's some software throttling of the reading to avoid having it change every time the car tilts up or down a hill.
