Audi Workshop Service and Repair Manuals

The new generation of central locking has self-diagnosis capability.
Using the fault memory, the final control diagnosis and the measured value blocks simplifies fault finding.
In addition, the V.A.G 1551 fault reader can be used to encode the associated central locking version.

The new central locking system always permits the "automatic open" or "automatic close" functions.
The "automatic close" function permits all opened windows and an opened sliding roof to be closed by holding the key in the close position until everything is closed.
When using "automatic open" hold the key in the open position until the windows are open.
The "automatic close" function cannot be executed on the tailgate lock.

The central locking has two pneumatic circuits. In central locking not equipped with remote control only the tank flap is connected to the first circuit and if radio remote control is fitted the driver door and the tank flap are connected to the first circuit. The remaining locking positions are connected to the second circuit.

If security central locking is fitted, unlocking the driver or front passenger door once opens only this door and the first pneumatic circuit. If a further unlock command occurs within 5 seconds, the second pneumatic control circuit is also activated and the entire vehicle opened.

If the tailgate lock cylinder is actuated only once, all doors remain locked. The tailgate re-locks automatically after approx. 5 seconds.

The interior lighting is dimmed on or off within approx. 1.5 seconds.

The luggage compartment lighting is controlled by the central locking system pump via the tailgate contact switch. If the tailgate is open, the lighting is switched off after exceeding a speed threshold (approx. 5 km/h) or after 10 minutes.

The new remote control system is now a radio remote control system.
In vehicles with radio remote control, the receiver is integrated in the central locking pump. The antenna for the radio remote control is integrated in the wiring loom.

If radio remote control is fitted, the "Comfort open" function only affects the windows. Press and hold the "Open Switch" to use this feature.

The "Comfort close" function can be used for the windows and the sunroof. Press and hold the "Close Switch" to use this feature.

The central locking system re-locks automatically if the doors or tailgate/ boot lid are not opened within 60 seconds of opening the central locking.

The central locking cannot be opened using the interior switch if the anti-theft alarm system is armed.

Vehicles with anti-theft alarm systems are always equipped with an ultrasonic interior monitor. All that is required is appropriate encoding of the central locking system .

It is possible to confirm that the anti-theft alarm system has been armed when locking the central locking. One form of confirmation may be a brief activation of the flashing telltale. The central locking can also be coded so that there is no confirmation.

Confirmation of the radio remote control can be indicated by flashing turn signal lamps.
