1.6.2 HIGH ADBLUE CONSUMPTION
General information
• Is this symptom the result of a technical fault?
• External factors or improper use can also lead to this fault.
• It is important to get the correct image of the complaint by
asking the customer or the driver for as much information
as possible.
Question
1. Ask for a good description of the use of the vehicle. The
AdBlue consumption depends to a large extent on the
use of the vehicle:
• Low loads can result in a reduced use or no use of
AdBlue.
• Heavy loads can result in an increased use of AdBlue.
• Long-lasting idling can result in a reduced use or no
use of AdBlue.
• Low ambient temperatures can result in a reduced use
or no use of AdBlue.
• High ambient temperatures can result in an increased
use of AdBlue.
Discuss the results with the customer or the driver.
Possible cause Remedy
Leaking AdBlue tank filler cap. Check the AdBlue tank’s filler cap (liquid or white
deposit) and, if necessary, replace it.
External AdBlue tank leak. Check the AdBlue tank for leaks (liquid or white deposit).
External AdBlue line leak. Check the AdBlue lines for leaks (liquid or white deposit).
Internal EAS unit leak. Check the outside of the EAS unit (liquid or white
