The gauge on my adblue tank reads "half full," so I went out and got some high-quality replacement fluid.

When I insert the pipe into the adblue container, nothing comes out. Any suggestions? :(

Because the vehicle's Nox sensors failed, it's possible that the previous owners mapped the ad blue system out of the ECU.

When you say the adblue won't get into the tank, do you mean it won't go in at all, or that it goes in but has no effect?

Welcome.

AdBlue tanks often don't need to be filled up between maintenance, and their 25-liter volume means they may last between 10,000 and 15,000 miles before needing to be refilled.

A problem with the AdBlue system is likely if your gauge displays just half a tank of gas and 2,700 miles of range left.

AdBlue problems, although common, may be difficult to identify and costly to fix. Does the automobile still have a valid warranty? If not, was it acquired from a dealer during the last 12 months? It has to be scanned for flaws in the ECU using STAR, which may be done at a Mercedes-Benz dealership or by an independent expert.

If I may make a recommendation, I would shorten your location to just the city and state.

In the absence of ad-blue, I would also break the spout seal.

Tank capacity does not correspond to the miles shown on the display. The gauge reads 100% yet the Mercedes Me app reports that I have 8000 kilometers left. It has from the beginning. Don't throw away your money on 5 or 10 liter containers if it won't use them. You may save 25% compared to "shop bought" top-up bottles by filling your tank with an AdBlue pump. In Germany, for instance, the price ranges from €2 to €2.5 per liter for bottles and €1.10 per liter at the pump. The last time I filled up in France, a week ago, the price per liter was €0.54.

Where does the OP go from here?
They signed up on Thursday at 5 a.m., asked a question, and then vanished at 5:24 a.m.

Still putting adblue in there, I'm guessing.
