Dosing module, urea injection

Hints & tips:

Exhaust gas cleaning through SCR technology (selective catalytic reduction) reduces nitrogen oxide emissions. For this process, the reducing agent is injected into the exhaust tract. When this mixture is exposed to heat, ammonia is produced, which converts the nitrogen oxide emissions into nitrogen (N₂) and water (H₂O).

When the dosing module is replaced, all the associated hoses and cables must also be replaced. It is furthermore important to make sure that the cables and electrical plugs are clean and securely attached.
