sitioner -G581-
– Connect multimeter to contacts 1 + 3 of connector using test
leads from -V.A.G 1594D- to measure voltage.
– Switch on ignition. Specification: at least 4.8...5.2 V
– Switch off ignition.
– Check wiring of position sender for charge pressure position-
er -G581- as follows:
– Using adapter cable -V.A.G 1598/39-1-, connect test box
-V.A.G 1598/42- to wiring harness of control unit
The engine control unit is not connected by this action.
– Check wiring between test box and connector for open cir-
cuit referring to current flow diagram.
◆ Contact 1 + socket 53
◆ Contact 2 + socket 58
◆ Contact 3 + socket 25
● Cable resistance: max. 2.0 Ω.
– Also check wiring for short to one another, short to battery
earth/engine earth and short to battery positive. Specifica-
tion: ∞ Ω
If no wiring fault is detected and voltage was present between
contacts 1 + 3:
– Renew position sender for charge pressure positioner
-G581-.
– Adapt position sender for charge pressure positioner -G581-

– Then, read event memory of engine control unit, and clear
event memory if necessary
If no wiring fault is detected and no voltage was present be-
tween contacts 1 + 3:
– Pull connectors off any components which are connected to
this voltage supply line
– Check voltage supply and wires on these components.
If no wiring fault is detected and no voltage was present on
these components:
– Renew engine control unit -J623-
