Summary
MIL on. DTC P20E9 is stored in the engine control module (ECM). In vehicles produced during a certain period, the AdBlue filter seal within the level sensor module may have been damaged during the assembly process. This damaged seal can allow unfiltered AdBlue to be sucked into the delivery system, subsequently damaging the pressure sensor and reducing agent pump V437.
