Removal and installation of control unit is described in the corresponding engine Workshop Manual in Repair Groups 01, 23 or 24.

→ Fig.5    Diagnostic connection

Fitting location: Diagnostic connection is located beneath knee restraint on left of steering wheel.

• ‒ Use diagnostic wire VAS 5051/1 to connect up vehicle diagnostic, testing and information system VAS 5051. Alternatively, use can be made of diagnostic wire V.A.G 1551/3 to connect up fault reader V.A.G 1551.

→ Fig.6    Valve body

Fitting location: Valve body is bolted to bottom of gearbox housing and covered by gearbox sump.

Solenoid valves -N88, -N89, -N90, -N91, -N92, -N93 and -N94 are attached to valve body. Solenoid valves -N91, -N92, -N93 and -N94 are also referred to as pressure control valves 1 (-N215), 2 (-N216), 3 (-N217) and 4 (-N218).

Removing and installing valve body

=> Automatic Gearbox 01V Front and Four-wheel Drive; Repair Group 38; Removing and installing valve body

A distinction is made between two types of gearbox:
Gearbox with hydraulic control E17 on which gearbox input speed sender (inductive pick-up) is attached to underside of valve body.
Gearbox with hydraulic control E18/2 on which gearbox input speed sender (Hall sender) is attached behind valve body to gearbox housing.

Information as to which gearbox is concerned can be found in the following Workshop Manual in the Repair Group given:

=> Automatic Gearbox 01V Front and Four-wheel Drive; Repair Group 00; Code letters, assignment of mechanical units, transmission ratios, features

→ Fig.7    Internal gearbox wiring harness with integrated gearbox oil temperature sender (ATF) -G93

Fitting location: Wiring harness is attached to valve body.

Wiring harness can be replaced with gearbox installed and valve body removed.

→ Fig.8    Multi-function switch -F125

Fitting location: Multi-function switch is located on left of gearbox, connector for multi-function switch -arrow-.

Use is made of two different multi-function switches:

1. Multi-function switch with 8-pin connector

2. Multi-function switch with 10-pin connector

Removing and installing multi-function switch

=> Automatic Gearbox 01V Front and Four-wheel Drive; Repair Group 38; Replacing multi-function switch

→ Fig.9    Tiptronic switch -F189

Fitting location: Tiptronic switch is integrated into printed circuit board of symbol panel, which is located in the shift mechanism cover.

Note:

This switch is not installed for shift mechanisms with no Tiptronic function.

It consists of 3 Hall sensors (-A-, -B-, -C-) which are actuated by a magnet on the transverse slide of the masking panel.

A - Change-down sensor
B - Tiptronic recognition sensor
C - Change-up sensor

Note:

A distinction is made between "old" and "new" Tiptronic strategy.

• ◆ "New" Tiptronic strategy means: On shifting selector lever to Tiptronic gate, gearbox automatically shifts up or down before speed governing limit is reached so that engine is always operating between idling and breakaway speed. Shiftdown is also automatically implemented if accelerator is depressed as far as kickdown.
• ◆ "Old" Tiptronic strategy means: On shifting selector lever to Tiptronic gate, gearbox only shifts up or down if selector lever is moved to front (+) or to rear (-). If vehicle is braked to a standstill, first gear is automatically activated for driving off.

• ‒ If faults occur, check Tiptronic switch in measured value block
  => Page 01-281 for
  malfunctions.

→ In the event of faults, start by checking whether magnet is properly attached to transverse slide -C- of masking panel and replace masking panel if necessary. Symbol panel with integrated printed circuit board is not to be replaced before checking wiring. On vehicles with Tiptronic sports steering wheel, the buttons on the steering wheel and their wiring must also be checked.

Removing and installing gearbox speed sender

=> Automatic Gearbox 01V Front and Four-wheel Drive; Repair Group 38; Removing and installing valve body; Replacing gearbox speed sender -G38

→ Fig.11    Gearbox input speed sender -G182

Fitting location:

On gearboxes with hydraulic control E17, gearbox input speed sender is located on underside of valve body (see Fig.). On such gearboxes the sender takes the form of an inductive pickup.

→ On gearboxes with hydraulic control as of E18/2, gearbox input speed sender -A- is attached behind valve body to gearbox housing. On such gearboxes the sender takes the form of a Hall sender.

Information as to which gearbox is concerned can be found in the following Workshop Manual in the Repair Group given:

=> Automatic Gearbox 01V Front and Four-wheel Drive; Repair Group 00; Code letters, assignment of mechanical units, transmission ratios, features
