AdBlue ® consumption
Like fuel consumption, AdBlue
highly dependent upon driving style and operat‐
ing conditions. For this reason, your vehicle's
actual consumption figures under normal operat‐
ing conditions may differ from the consumption
figures calculated. AdBlue
between 1% and 5% of fuel consumption. Have
the AdBlue
