BATTERY DISCONNECT PROCEDURES

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.

Before beginning repairs on the electrical system

1. Obtain the anti-theft radio security code.
2. Switch off all electrical consumers.
3. Switch ignition off and remove ignition key.
4. On vehicles equipped with Audi Telematics by OnStar, switch-off the emergency (back-up) battery for the Telematic/Telephone Control Module prior to disconnecting vehicle battery. See «Back-Up Battery For Telematic/Telephone Control Module»(/audi/a4/b6-2000-2006/remont/automatic-trans/#continuously-variable-transmission-cvt-01j-removal-installation__back-up-battery-for-telematictelephone-control-module) .
5. Disconnect negative ( - ) battery terminal.

After reconnecting vehicle battery

1. Re-code and check operation of anti-theft radio
2. Check operation of clock and power windows. See «Power Window Control Module»(/audi/a4/b6-2000-2006/remont/automatic-trans/#continuously-variable-transmission-cvt-01j-removal-installation__power-window-control-module) .
3. On vehicles equipped with Audi Telematics by OnStar, switch-on the emergency (back-up) battery for the Telematic/Telephone Control Module. See «Back-Up Battery For Telematic/Telephone Control Module»(/audi/a4/b6-2000-2006/remont/automatic-trans/#continuously-variable-transmission-cvt-01j-removal-installation__back-up-battery-for-telematictelephone-control-module) .

Power Window Control Module

If the battery is disconnected, the window control module loses its memory of current position and the automatic up/down function. To reset

1. Switch ignition on.
2. Lift window switch up to run power windows up to stop.
3. Operate all window lifters again for at least 1 second in "close" position to activate automatic up/down function.
4. Press window switch briefly.
5. The selected side window must automatically run to the bottom stop.

Back-Up Battery For Telematic/Telephone Control Module

Switching back-up battery on or off requires using factor scan tool VAG 1551 or VAS 5051 Scan Tool (ST), or equivalent aftermarket scan tool.

Under "Rapid data transfer" operating mode 1, select "Telematics" address word 75. Then select function "10 - Adaptation".

Emergency (back-up) battery, switch on/off, reset time register can be selected from this mode. Consult scan tool operator's manual for instructions.

3. Perform measurement by passing sliding calliper with depth gauge through hole used for securing converter. (Scheme 164) Specification: 18.9-20.5 mm.
4. If measured value exceeds specification, remove drive plate again and correct value by installing with/without shim -2-. Tighten bolts to 30 Nm again.
5. Measure distance again.
6. If measured value matches specification, install new bolts and tighten. See «TORQUE SPECIFICATIONS»(/audi/a4/b6-2000-2006/remont/automatic-trans/#continuously-variable-transmission-cvt-01j-removal-installation__torque-specifications).

TRANSMISSION MOUNTING BOLTS

Note. Engine-to-transaxle tightening torques are valid only for nuts and bolts that are lightly greased, oiled, covered with a thin coat of phosphate or blackened. Other lubricants are permitted (e.g. engine oil or transaxle fluid); however, they may not contain graphite. Do not use any degreased parts. To install lower engine-to-transmission bolts, lift rear of transmission slightly. Tolerance for tightening torques is 15% more or less.
