AdBlue warning light with countdown showing kilometres remaining before engine start prevention. The W205 C-Class diesel uses selective catalytic reduction (SCR) and requires regular AdBlue (urea solution) top-ups. The tank capacity is 13.5 litres and consumption is approximately 1 litre per 1000 km. AdBlue is available from fuel stations and automotive retailers. Use only ISO 22241 certified AdBlue — using windscreen wash or water in the AdBlue tank causes expensive SCR system damage.
