Volkswagen Workshop Service and Repair Manuals

Note:

The basic setting is carried out jointly by the load signal potentiometer -G157- and clutch pedal movement sender -G162-.

The basic setting should be initiated after performing the following repairs:

• ◆ Exchanging engine
• ◆ Replacing clutch electronics control unit
• ◆ Replacing Diesel injection pump
• ◆ Load signal potentiometer -G157-
• ◆ Changes to adjusting lever, adjustment of residual quantity or maximum speed adjustment screw on injection pump
• ◆ Replacement or adjustment of clutch or clutch positioner

• ‒ Connect fault reader V.A.G 1551, enter address word "12 Clutch electronics" and advance programme until "Select function XX" is shown on display => from Page 01-33 .
• ‒ Engage 1st gear and apply hand brake (do not start engine).

• ‒ Press keys 0 and 4. (04 selects function "Basic setting".)

Note:

Accelerator pedal must remain in idling position.

• ‒ Confirm entry with key Q.

• ‒ Press keys 0 and 0.
• ‒ Confirm entry with key Q.

(Gearshift indicator warning lamp -K48- comes on briefly).

The system is now in the basic setting.

• ‒ Floor accelerator pedal and hold in this position for 3 seconds.
• ‒ Press key ⇒.

• ‒ Disconnect V.A.G 1551 from diagnostic sockets and place gear stick in neutral.
• ‒ Start engine and run vehicle for about 30 seconds at idling. (Ecomatic switches in, Ecomatic warning lamp -K110- does not light up.) If the necessary "initial slip point" is attained within the 30 seconds, the engine switches off.
• ‒ To search for the slip point carry out a test drive.

Perform test drive as follows:

Note:

Do not operate clutch with vehicle raised.

• ‒ After pulling away engage 2nd gear.
• ‒ Without changing gear operate clutch 10 times.
• ‒ When doing this, starting from idling speed always give at least 50% throttle.

Herewith the search for the clutch slip point in basic setting is completed.

With every further clutch operation the slip point will be adapted by control unit -J327-.
