TRANSAXLE APPLICATION

TRANSAXLE IDENTIFICATION PLATE

Transmission code letters are given on type plate at bottom of transmission (arrow). (Scheme 1)

The transmission code letters are also listed on the vehicle data plates.

Scheme 1

Scheme 2

Transaxle

Check fluid level at 20,000 mile intervals. Fluid is filled for life. No changing is required.

Center Differential & Final Drives

Check fluid level at 20,000 mile intervals. Fluid is filled for life. No changing is required.

CHECKING FLUID LEVELS

Note. ATF level is affected by ATF temperature. Checking ATF level at too low a temperature leads to overfilling. Checking ATF level at too high a temperature leads to under filling. Overfilling or under filling transaxle can lead to transaxle malfunction.

01V Transaxle

Note. VAS Scan Tool (5051) is required to check ATF level. Scan tool is used to measure ATF temperature. Follow aftermarket scan tool manufacturer instructions (if applicable) to check ATF temperature.

Remove ATF inspection plug from oil pan. (Scheme 5) A small amount of ATF should drip from inspection hole with engine running. If level is okay, install NEW seal on inspection plug and tighten to 59 ft. lbs. (80 N.m). Turn engine off. Select diagnostic function "06 - end output". Procedure is complete.
5. If additional fluid is required, using ATF Filling System (VAG 1924), carefully insert fill hose through an opening in the deflector cap. (Scheme 6) Ensure deflector cap is not pushed upward out of position. Fill until ATF runs out of inspection hole. Use VW ATF fluid only. DO NOT use any lubricant additives.

REMOVAL & INSTALLATION

BATTERY DISCONNECT PRECAUTIONS

Note. When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle.

Air Bag

ECM

If connector is disconnected from ECM or battery is disconnected, all adaptation values in control module are erased. To achieve optimal anti-theft protection for vehicle, an anti-theft immobilizer was installed. Anti-theft immobilizer is a system for enabling/locking Engine Control Module (ECM) through the W-wire.

This system cannot be circumvented, it is necessary to perform adaptation of anti-theft immobilizer using VAS 5052 in On Board Diagnostic function. The great availability of equipment options makes adaptation of ECM necessary (e.g. cruise control system). This "writing" function is not possible with a generic scan tool, therefore it is necessary to use VAS 5052 in On Board Diagnostic function for this purpose. DTC memory content will remain intact however. If engine is started after this, a rough, uneven idle can result. In this case, ECM readiness code must be regenerated.

ECM Readiness Code

While limited diagnostic information is available, vehicle manufacturer does not support diagnostic information using aftermarket scan tools. To properly diagnose vehicle, it is recommended to use VAS 5051 scan tool with VAS 5051/1 adapter cable or VAG 1551 scan tool with 1551/3A adapter cable and VAG 1598/31 test box.

Readiness code must be generated when Engine Control Module (ECM) memory is cleared, battery voltage is disconnected or ECM is disconnected. To generate readiness code, vehicle must be stationary, transmission in Park or Neutral, all electrical consumers off, A/C switched off and coolant temperature at least 176° F (80° C). If possible, it is best to warm-up vehicle by test driving. Connect scan tool to DLC. DLC is located behind cover under left side of steering column.

Power Windows

After connecting battery, completely open and close all power windows.

Radio & Clock

Vehicles are equipped with an anti-theft stereo system that requires a code to activate. Record stereo code BEFORE disconnecting negative battery cable. Disconnect negative battery cable. Turn ignition to ON position. Reconnect negative battery cable. Enter code into stereo and reset clock.

Telematics

Note. A4 and A4 Quattro are equipped with Audi Telematics by OnStar(R).

To avoid unnecessary discharge of emergency (back-up) battery, it must always be switched off, prior to disconnecting vehicle battery, and switched back on after vehicle battery is reconnected.

Use VAS 5051 in mode "Guided Fault Finding". Enter appropriate model, equipment and model year. Press ">" to confirm. After control modules have been registered, and DTC memories checked, press "Go To". Use the following prompts to switch off/on emergency (back-up) battery

1. Select "Function/Component Selection".
2. Select "Body".
3. Select "Electrical Equipment".
4. Select "01 - On-Board Diagnostic Systems".
5. Select "Telematic".
6. Select "J526 - Telephone/Telematic Ctrl. Module, Service Mode Disc. Battery". If necessary, press ">" to advance.
7. To switch OFF emergency (back-up) battery, select/press button "3" - Service Mode Activating (No Load On Emergency Battery).
8. Follow tester prompts.
9. To switch ON emergency (back-up) battery, select/press button "1" - Service Mode Deactivating (Normal Operating Condition).
10. Follow tester prompts.

(Scheme 19) (If A/C control head is difficult to remove, proceed as on vehicles with Radio-Navigation system.) NOTE: The A/C control head is secured in the center console with 4 retaining clips (A).
2. On vehicles with Radio-Navigation system or radio with large control panel, remove radio or radio-navigation system. See «RADIO»(/audi/a4/b6-2000-2006/remont/automatic-trans/#servicing-at-01v-with-18l-30l). Reach through the opening and push the A/C control head toward the rear out of center console.

Note. A faulty double sealing ring will allow ATF or gear oil to escape into the converter housing through the center breather (between the 2 sealing lips) of the shaft seal. Faulty double sealing ring can also allow ATF to get into the differential section of the transaxle. The differential section becomes overfilled and oil escapes from the breather.

Replace gaskets on flange shafts (detach protective foil and stick gasket onto flange shaft). It is essential that the locking fluid remaining in the threads in the flange shafts on the transmission and rear final drive is cleaned out after removing the drive shaft. Otherwise there is a danger that the new bolts will seize when they are screwed in and then shear if they have to removed later. The threaded holes can be cleaned with a thread tap. REPLACE drive shaft bolts (self-locking).
8. Install heat shield for driveshaft on cover for differential. Install front exhaust system with catalytic converter. Tighten bolts and nuts to specification.

4. To install new selector lever knob (3), button (2) must be pulled out as far as stop and secured with a cable tie (arrow) or using assembly aid included with new knob. (Scheme 48) If the button was accidentally not secured, then it must not be pulled from selector lever knob using mechanical tools. Apply compressed air gun to bottom of knob and carefully press button out with compressed air.
5. Position complete selector lever knob (3) on selector lever (button -2) faces driver. (Scheme 48) During this, the knob must engage into ring groove of the selector lever. Remove cable tie (arrow) or assembly aid, then button actuation engages in vertical groove of selector lever. If necessary press button into selector lever knob. Pull sleeve (1) upward and engage by turning clockwise.
