Battery, Disconnecting and Connecting

• After the ignition is switched off, the reducing agent goes from the metering line to the reducing agent injector (N474) and back into the reducing agent active chamber.

• Wait until all the reducing agent has been returned before working in this area. This could take up to 10 minutes after switching off the ignition.

• Only after this is complete can the battery be disconnected. Again, this could take up to 10 minutes after switching off the ignition.
