1998 Audi A8 Sedan (4D2) V8-3.7L (AEW)SECTION Remote Unit For Central Locking Operation, Coding and Erasing
CODING
On vehicles with remote control central locking, every new or non-encoded remote unit must first be re-coded for the central locking control module.
- Switch ignition on; leave key in ignition.
- Mechanically lock vehicle at left-front door, using second key.
- On remote unit, press "Open" button once. Short horn signal will sound.
NOTE:
- The "Open" button is pressed once for programming the first or a single, remote unit.
- When programming additional remote units for the second, third or fourth memory addresses, press the "Open" button two, three or four times, in one-second intervals.
- Example: press the "Open" button once, wait 1 second, then press once again to program the second remote unit.
- After 6 seconds, press "Open" button once to activate coding process.
The remote unit will now be coded, and it can be used to unlock the central locking system.
- Switch ignition off.
NOTE: The key must be removed from the ignition before the remote unit can be used to lock the vehicle.
The coding process can be repeated up to 4 times for additional remote units. In between each remote unit coding, the ignition must be switched off.
ERASING
NOTE: It is possible to erase the memory, e.g. if the customer has lost a remote unit. Proceed as follows.
- Using key, switch ignition on.
- Mechanically lock vehicle at left front door, using second key.
- On remote unit, press "Open" button 5 times in one-second intervals. Short horn signal will sound.
- After 6 seconds, press "Open" button once to activate memory erasing process.
- The memory is now erased, and the central locking system can no longer be operated by the remote unit.
- Switch ignition off.
As many as 4 new remote units can now be coded.
