Automatic Transmission Control Module (TCM) -J217-, removing and installing
Removing
- Remove lower right A-pillar trim and right front door sill trim.
- Detach carpeting from right inside door sill, and raise carpeting approx. 20 cm.
- Unclip box at -A- by pulling it upward.
- Unclip box at -B- as shown.
- Unclip TCM from box (arrows).
- Release catch on multi-pin connector and disconnect connector from TCM.
Installing
Install in reverse order of removal, with the following additional steps:
- Check that clip nut -1- is properly secured.
TCM -J217-, disconnecting
- Switch ignition off and wait approx. 30 seconds.
- Release connector by pressing catch in direction of arrow.
Connect in reverse order of disconnecting.
Engine Control Module (ECM)
Location: in electronics box (E-box) in plenum chamber (left side).
Data Link Connector (DLC)
Location: Up to m. y. 2000, the Data Link Connector (DLC) is located under the rear ashtray (center console).
As of m. y. 2001, the DLC is located under the kneebar left of the steering wheel.
- Connect VAS 5051 tester with VAS 5051/1 diagnostic wire, or connect V.A.G 1551 Scan Tool with VAG 1551/3 adapter.
- Enter address word "02 transmission electronics" and continue switching until "selecting function XV appears on display.
Valve body
Location: The valve body is bolted to the underside of the transmission housing inside the oil pan.
The Solenoid Valves -N88-, -N89-, -N90-, -N91-, -N92-, -N93- and -N94- are attached to the valve body. The 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
There are two types of transmissions:
^ For transmissions with hydraulic regulation -E17-, the transmission input speed sensor (inductive sensor) is secured to the underside of the valve body.
^ For transmissions with hydraulic regulation -E18/2-, the transmission input speed sensor (camshaft position sensor) is secured behind valve body at transmission housing.
Wiring harness with integrated Transmission Fluid Temperature Sensor -G93-
Location: The wiring harness is secured to the valve body.
The wiring harness can be removed with the valve body removed and the transmission installed.
Multi-function Transmission Range (TR) switch -F125-
Location: The multi-function switch -1- is located on left at transmission; Multi-pin connector for multi-function switch -arrow-.
Tiptronic switch -F189-
Installation location: The tiptronic switch is integrated into the conductor strip of the symbol insert in the cover of the shift mechanism.
Note:
This switch is not installed on shift mechanisms without tiptronic function.
The switch consists of 3 hall-effect sensors (-A-, -B-, -C- ), which are activated via a magnet on the lateral gate cover of the gate cover.
A - Sensor for down-shift
B - Sensor for Tiptronic-recognition
C - Sensor for up-shift
- If malfunctions occur, the switch for tiptronic must be checked for interference in Read measuring value block.
In case of problems, first check the magnet at the lateral gate cover -C- of the gate cover is properly attached, replace gate cover, if necessary. Only replace the symbol insert with integrated conductor strip after checking the wires. For vehicles with tiptronic-sport steering wheel, also check the buttons at steering wheel and their wire connections.
Transmission Vehicle Speed (VSS) Sensor -G38-
Location: The transmission vehicle speed sensor is located at right rear in the transmission. It is also referred to as the Sensor for Transmission Output RPM -G195-.
Sensor for Transmission RPM -G182-
Installation location:
On transmissions with hydraulic regulation -E17-, the Sensor for Transmission RPM is secured to the underside of the valve body (see illustration). For these transmissions the sensor is an inductive sensor.
On transmissions with hydraulic regulation -E182-, the transmission input speed sensor A- is secured behind the valve body at the transmission housing. On these transmissions the sensor is a hall effect sensor.
Shift Lever Lock Solenoid -N110-
The Shift Lever Lock Solenoid is located in the shift lever housing -arrow-.
Throttle Position (TP) Sensor -G69-
Location: integrated in Throttle Valve Control Module -J338- -arrow-.
Starting interlock relay -J207-
The relay is located on the central electric.
Transmission range selector lever display -Y6-
Located in instrument cluster
Kick-down switch -F8-
Engines without E-Gas:
The kick-down switch is integrated in the accelerator cable in the plenum chamber, behind bulkhead -arrow-.
Engines with E-gas:
The kick-down switch is integrated in the throttle position sensor and Sensor 2 for Accelerator Position (-G79-, -G185-).
A learning procedure must be performed for the shift point of the kick down switch for engines with E-gas. If the throttle position sensor (-G79-, -G185-) is removed, exchange the engine control module or disconnect the battery.
Kick-down switch, removing and installing
- To remove and install the kick down switch, the accelerator cable must be removed and installed and then adjusted or the throttle position sensor (38-G79-, -G185-) must be replaced.
Brake light switch -F-
The brake light switch -arrow- is located on the pedal cluster.
Note:
For engine with E-gas, the brake light signal is transmitted from the engine control module to the transmission control module via the CAN-Bus.
