The advantages of OBD can only be fully
exploited by using the vehicle diagnostic, testing
and information system VAS5051 or the
VAG1551 scan tool, in operating mode 1 "Rapid
data transfer."
The DTC memory is equipped with a permanent
memory and therefore does not depend on the
power supply.
The stored malfunctions will be displayed after
checking the DTC memory Page 01

.
After eliminating malfunctions the DTC memory
must be erased Page 01

Important note:

Every time the DTC memory is erased and the
voltage supply to the Motronic Engine Control
Module (ECM) -J220 has been interrupted the
readiness code must be generated Page 01
