NOTE: In some cases, the engine will enter the de-rate mode.
The above error codes result from low pressure in the AdBlue system. In most cases, the low pressure is due to debris in the AdBlue system. This debris can lead to blockage of:
A breather line in the AdBlue system
One of the filters in the AdBlue system
For production:
To overcome these concerns NEW HOLLAND introduced the below updates on Tier4B flagship combines and Midrange combines:
The installation of a filter on the vent line of the AdBlue tank.
NOTE: Previously on Tier 4A combines, the vent line was open to the atmosphere so debris could enter into the AdBlue system at this point.
The Introduction of a larger in-line filter on the suction line between the AdBlue tank and the Dosing Control Unit (DCU).
NOTE: This larger in-line filter has a much longer service interval than the previous in-line filter on tier 4A combines.
For service:
To overcome any service concerns NEW HOLLAND introduced the below updates for use on Tier4A combines:
A filter with associated hardware for the vent line of the AdBlue tank.
A service kit 48041490 to retrofit the larger in-line filter onto Tier4A combines.
