New Holland 19818 – New Holland Dosing Control Unit Dcu: Plausibility of UDV Stuck – P202D Dynamic Urea Leakage Test – Leakage Detected

The system has detected a plausibility issue indicating that the UDV (urea dosing valve) may be stuck, as determined by the P202D dynamic urea leakage test. This suggests that urea leakage has been detected during the test, which may indicate a fault in the urea dosing system.
