CAUTION!
After repairs the DTC memory of the engine control module must always be checked and
the DTC memory content "Engine control module blocked" erased. Check and eliminate
any further malfunctions stored.
Notes:
All static and sporadic malfunctions are stored in the DTC memory: A malfunction is
recognized as a static malfunction when it is present for a minimum of 2 seconds. If
the malfunction is no longer present after this time, it is stored as a sporadic fault
and "/SP" appears on the display.
After switching on the ignition, malfunctions stored are first recognized as sporadic
and are changed to static if they are present after the check has been completed.
If a sporadic malfunction is no longer present during the next 50 driving cycles
(ignition on for a minimum of 2 seconds) it is erased.
The following table lists all the malfunctions, with the corresponding 5-digit code
numbers, that can be recognized by the immobilizer control module and printed out
by the VAG 1551.
DTCs appear only on a print-out.
Before replacing a component shown as faulty, check wiring and connections to the
component as well as Ground connections according to the wiring diagram.
When the repair has been completed, the DTC memory must always be checked
again with the VAG 1551 and then erased.
