General notes on ignition system

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2009 Audi S4, 2008 Audi S4, 2007 Audi S4, 2006 Audi S4, and 2005 Audi S4. However, it is still accessible from the selected car via links, so may be relevant.

The engine control module is equipped with On Board Diagnostic (OBD).
A voltage of at least 11.5 V is necessary for satisfactory functioning of the electrical components.
In the case of some tests, a malfunction may be recognized and stored by the control module. At the end of all tests and repairs, the Diagnostic Trouble Code (DTC) memory should be checked and, if necessary, erased.
If the engine starts briefly and then stops after the DTC search, repair or tests on components, this may be because the immobilizer is blocking the engine control module. The DTC memory must then be checked and, if necessary, adaptation carried out on the control module.
