variation can also be coded using the VAG1551
Scan Tool (ST).

central locking without keyless entry, the first
circuit controls only the fuel filler flap; for central
locking with the keyless entry system, the first
circuit controls both the fuel filler flap and the
driver-side door. The second circuit controls all
remaining locking point s.

On the safety-version of central locking, if the

driver-side (or passenger-side door) is unlocked
with a single command, then only that door and
the first pneumatic circuit are opened. If there is
another unlocking command within 5 seconds,
the second pneumatic circuit is also triggered
and the whole v ehicle is unlocked.

If the rear lock cylinder is triggered only once, all

doors will remain locked. The rear lid (or tailgate)
will automatically re-lock itself after about 5
seconds.

The control of the luggage compartment lighting

proceeds from the central locking pump to the
rear lid (or tailgate) contact switch. The lighting
will be switched off while the rear lid is open
when a certain speed threshold is surpassed
(about 5 km/h) or after 10 minutes.

The new remote transmitter now uses radio

frequency. For vehicles using the radio frequency
remote locking system, the receiver is integrated
into the central locking pump. The remote locking
antenna is integrated into the wiring harness.

If no doors (or the rear lid) have been opened

within 60 seconds after the central locking
system is triggered via radio frequency, central
locking automatically relocks everything.

If the anti-theft alarm system is armed, central

locking cannot be opened via internal buttons.

All vehicles with an anti-theft system are

equipped with an ultrasonic interior monitoring
system. This could be an interior monitor of the
1st generation (without OBD) or of the 2nd
generation (with OBD). All that is necessary is
the proper coding of the central locking system

page 01-91 .

Confirmation can be received fr om centr al

locking as to whether the alarm system has been
armed while locking the doors. The confirmation
can be signalled by means of a short anti-theft

emergency flashers. Central locking can also be
coded to give no confirmation at all.

Activation of keyless entry can be signalled by a

flashing of the emergency flashers.

Diagnostic Trouble Code (DTC) table, central locking

Notes:

The following table lists all the DTCs that can be recognized by the control module for central locking and printed out by
the VAG1551 Scan Tool (ST). The DTCs are listed in order according to their 5-digit numbers.

DTC 5-digit numbers appear only on the print-out from the scan tool.

Before replacing a component shown as malfunctioning, check wiring and connections to the component as well as the
Ground (GND) connections according to the relevant wiring diagram.

When a repair has been completed, check and then erase DTC memory using the VAG1551 Scan Tool (ST). After that,
the vehicle should be locked again (with key or remote control) and DTC memory checked again.

DTC memory records all static and sporadic malfunctions. When a malfunction occurs, it is first identified as a static
malfunction. If it does not occur again it is registered as a sporadic malfunction, and the letters "/SP" appear at the right of
the display.

When the ignition is switched on, all existing malfunctions are automatically re-classified as sporadic malfunctions and will
only be registered as static malfunctions if they still occur after testing.

Sporadic malfunctions which no longer occur after 50 driving cycles are erased automatically.

The three digit malfunction type number appearing next to the DTC is a data code which may be disregarded.
