Procedure:

1. Check the urea concentration with the detector, qualified if shown 32.5%.

2. Remove the AdBlue tank and wash the tank interior, and the level quality sensor.

3. Clear the Diagnostic Trouble Code and fully deliver.

4. The repeated question occurs if after 2 days of use, it might not be an accidental issue.

See the voltage data of the AdBlue level quality sensor connector. CAN-H 2.3V,CAN-L 1.9V, power supply 24V; change the danged sensor if you see normal G and normal voltage.

After several checkouts, the issue can narrow down to a certain part; then you can solve it instead of replacing the whole construction.
