AdBlue consumption
The average AdBlue ® consumption is between
1% and 5% of fuel consumption. Like fuel con‐
®
sumption, AdBlue consumption is highly
dependent upon driving style and operating con‐
ditions. For this reason, your vehicle's actual
consumption figures under day-to-day operating
conditions may differ from the consumption fig‐
ures calculated. The frequency at which you will
