AdBlue warning with engine start prevention countdown on the Mercedes Sprinter 314 CDI. Commercial operators sometimes neglect AdBlue top-ups as the warning gives several hundred km before shutdown. If the system runs dry, the SCR catalyst requires a complex reset procedure at a Mercedes dealer. Always top up AdBlue before the warning appears. Use only ISO 22241 certified AdBlue — contaminated AdBlue destroys the SCR catalyst, costing thousands in repairs.
