Removing and installing fuel pressure senderG247

Removing and installing fuel pressure sender -G247-

If the fuel pressure sender -G247- fails, the fuel pressure regulating valve -N276- is switched off, the electric fuel pump is fully activated and the engine is operated with the fuel pressure which remains. This will reduce engine torque considerably.

Special tools and workshop equipment required

t	Assembly tool -T10118-

t	Double hexagon socket 1/2", 27 mm -VAS 5301/7- or commercially available socket (27 mm)

Removing

WARNING

The fuel system is pressurised. The fuel pressure in the high-pressure part of the injection system must be reduced to a residual pressure prior to opening; for procedure see → Chapter.

–	Unplug connector -1- and remove fuel pressure sender -G247--2-.

Installing

–	Install in reverse order.

l	Tightening torques: refer to intake manifold (part 2) - exploded view → Chapter
