The volume of the tank on your Movano is 22,5L.
The remaining percentage of AdBlue® currently remaining can be displayed on the board information display of the driver by pressing several times on the knob at the end of the wiper's lever to show the menu "percentage of remaining AdBlue®". If the level of AdBlue® drops below a 1500 miles of mileage, a warning message showing "AdBlue® mileage: 1500 miles" is displayed on the driver's information display. Driving is possible without any restrictions. When the remaining mileage drops to 600 miles, warning messages are displayed alternatively on the information display of the driver: "AdBlue® Level Low, fill up now?" "Imposs. restart engine in 1500 miles". The Y warning light flashes without interruption and an alarm signal sounds 4 times every 3 minutes. Before the driving prohibition is locked, the following warning messages are displayed:" AdBlue® empty, fill up now? no engine restart", the Y warning light stays illuminated and an audible signal rings 4 times every 3 minutes. After driving prohibition, the following message will be displayed:"Fill up AdBlue® to restart engine." A volume of at least 5 litres of AdBlue® needs to be added during fill up in order for the new level of AdBlue® to be detected by the system and that the warning light extinguishes.
Even if the tank is empty, you can continue to drive, as long as your engine is not turned off. As soon as the engine stops running, it will not restart. If the new level of AdBlue® is not correctly detected by the system, drive continuously for 10 minutes while making sure that the speed of the vehicle is always greater than 13 miles/hour. When the AdBlue® fill-up is correctly detected, the limitations induced by the supply of AdBlue® will vanish.
This information can vary on some vehicles of the same model in relation to the options chosen by the manufacturer.
