	Intank fuel pump relay, task	The intank fuel pump relay actuates the intank fuel pump (M3/1).
	Intank fuel pump relay, design	The intank fuel pump relay is a 4-pin plug relay
	Intank fuel pump relay, function	When actuating by means of the ME control unit (N3/10) using a ground signal, it closes the power contact and thus supplies the intank fuel pump with voltage from "circuit. 87" For model 230 up to 06/2002 actuation of the intank fuel pump relay is via the intank fuel pump control unit (N118/1).
