Default Ad Blue safe mode

I was just about out of adblue, so i put in one liter from the dealer, as i didnt know how to put the big jug i bought in at the time with that little adapater. I drove some more and it said i was running low again. Aparently when it runs low twice i hear it goes into some sort of safe mode? So i shut the car off and now the car wont start, i put more in the car nothing. Not sure what else to do. Anyone else have this issue,

I heard you might be able change adaptive settings or i may have too look at the dpf for some reason? I can post the current scan in, in the hopes someone can help me out here, not sure what to do. please pm me or email if u have any useful help, thanks in advance.

I'd disconnect the battery for a bit first. Then try to start it. Hopefully that resets the computer to check the level.

There have also been some reports of bad def sensors that required them to be replaced. If you have vcds and can read the codes that should lead you to which option you might have to pursue.

Fill the Adblue tank all the way to the top. It's cheap enough that you should refill it every oil change and then won't have this problem. Get a Cruze bottle and a 2.5 gallon of DEF from your ffavorite auto parts place. Unscrew the top of the cruze bottle after emtptying into the tank, and refill from the bulk jug until the the tank is full. Holds 4.6 gallons in total.

If it isn't showing you the warnings, then it probably isn't inhibiting the start. I would start looking at other problems like maybe a bad in-tank fuel pump.

fyi to make it know how much is in it , fill it up with however much you have , full or 1 liter doesn't matter , turn the key to the position just before starting and let it sit for 30 seconds with the key in that position and then it will know the level .

You have to add enough to bring the level above the next sensor probe. There are three probes. Sometimes 1L isn't enough.

Yes that and also, in the owners manual, its written that once you had the adblue to proper level, you have to turn the key at the "on" position (engine not running) and stay like this for a minimum of 30 seconds to "tell" the sensor to take the reading and resets the warning message.

single94 - did the car display a no-start warning? This is critical info in determining whether or not your no-start is related to DEF or something else.

No Hijack meant here, but is there a part number for the Cruze DEF bottle for online ordering?
