Danger ! | Risk of burn injuries and scalding when working at AdBlue lines and the components attached to them. Risk of injury to skin and eyes when handling AdBlue. Risk of poisoning caused by swallowing AdBlue | Pour AdBlue into suitable containers only. Wait until the pressure is released before starting any work on the exhaust aftertreatment system. | |
| Notes on use, material properties and handling of AdBlue® | ||
1 | Switch off ignition | ||
2 | Open maintenance flap | ||
3 | Connect diagnostic system and start XENTRY | ||
Danger ! | Risk of injury caused by body parts being pinched or crushed as cab is tilted | Ensure that no one is within the tilting range of the cab as it is being tilted. Always tilt the cab all the way to the end position and secure with the safety strut. | |

5 | Install test connection (4) at compressed air inlet of metering device (1) | Retrofit test connection on compressed air inlet of metering device | |
Only if no test connection (4) is installed. | |||
6 | Remove SCR air pressure sensor (B128) | ||
7 | Fill water in the hole (6) | Fill water until it overflows from the hole (6). | |
8 | Install the SCR air pressure sensorB128 | SCR air pressure sensor on metering device | |
9 | Connect up flushing hose (3) to test connection (4) | A measuring hose can be used as a flushing hose (3). | |

10 | Remove tire valve on flushing hose (3) | ||
11 | Fill sufficient water into the flushing hose (3) so that a water column (A) of 4 cm is achieved | Hold the flushing hose (3) at a height during the process so that the water flows in the direction of the test connection (4). | |
12 | Screw tire valve onto the flushing hose (3) | ||
13 | Attach compressed air guns (2) to flushing hose (3) | ||
14 | Flush out metering device (1) | | |
To do this, pressurize the flushing hose (3) with compressed air until the water is completely removed. | |||
Danger ! | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |
15 | Start engine | ||
16 | Check compressed air pressure on the metering device (1) with the aid of the diagnostic system through querying the actual value 69 | If the value is outside the tolerance range specified in the diagnostic system, the flushing process must be repeated. If the value is still not correct: | |
| |||
Replace diffusor and sieve on the compressed air inlet of the metering device. | |||
Replace diffusor on metering device. | |||
Replace sieve on compressed air inlet of the metering device. | |||
17 | Remove flushing hose (3) | The test connection (4) can remain in the vehicle. | |
Danger ! | Risk of injury caused by body parts being pinched or crushed as cab is tilted | Ensure that no one is within the tilting range of the cab as it is being tilted. Always tilt the cab all the way to the end position and secure with the safety strut. | |
18 | Tilt back cab | ||
