If the specified value in display field 2 for "cruise control system release" (1000) is not obtained:
- Check control module identification of current Engine Control Module (ECM).
VAG1551 scan tool display indicates control module coding, for example:
4D0907558. 4.21 V8/5V G *D2US ->
Coding 06753 WSC 06812
- 4D0907558.. Control module number (see replacement parts program)
- 4.2l Engine displacement
- V8/5V Construction style of engine (V engine, 8 cylinder, 5 valves)
- "G" i.e. no indication Vehicle with or without cruise control system
- D.. Data version (software version) of control module
- Coding 6753 Engine Control Module (ECM) coding
- WSC 06812 Factory identification from VAG1551, with which the last coding was performed
If there is no "G" under component identification, cruise control must be activated first.
Only for vehicles with automatic transmission:
- Road test vehicle and exceed 30 km at least once. Do not switch off engine upon completion. Leave selector lever in -2-, -3- or -D-.
- Engage parking brake.
NOTE: For vehicles with automatic transmission, the voltage supply for the cruise control switch is not switched on until a speed of above 30 km/h is reached with selector lever in position -2-, -3- or - D-. The voltage supply will then be maintained at ideal, as long as a driving mode (aside from -1- or -R-) is selected.
