Code P1447

Post by nj325ci »

CEL came on in our e90. My generic code reader pulled “P1447 - diagnostic module tank leakage too high during solenoid switching test”

Is this a generic fault description and is there a most common cause? On line I’m seeing several potential causes from the old gas cap issue to the DTML pump. Would anyone have any insight?

Thanks very much, Bill
