General notes on immobilizer V
The immobilizer V was introduced with the Audi A5 Coupé and is also fitted on the A4 and Q5.
The function test to adapt the immobilizer V in Guided Fault Finding is „* * - Service immobilizer“.
The function test is modular and also evaluates messages from the SeCo database. As modules are interchangeable, no actual components appear in the generated messages, only virtual control units. For this reason, the designations of some components differ from those shown in the current flow diagram. The table → Chapter lists all components and designations from the function check.
