This Fault Code can be stored in due to Remote Control or Immobilizer Problems. On most Models these systems are separate and should therefor also be diagnosed separately.
In case of Engine Starting Issues please make sure that you are really experiencing an Immobilizer related Problem! On most models using conventional keys, the Engine will still start cut out after 1-3 Seconds if an Immobilizer related Problem is the cause. However, on models using Kessy Systems and electronic keys, most systems in the car won't power up at all if if an Immobilizer related Problem is the cause. If you are NOT experiencing this behavior (e.g. instruments power up, and engine cranks but doesn't fire at all or engine won't crank) this is likely NOT Immobilizer related.
When found in Audi A3 (8L), Audi A4 (8D), Audi A6 (4B) or Audi A8 (4D), check Wiring from Immobilizer Control Module to Immobilizer Reader Coil. A known issue would be the Length of the Wiring, an optimized Replacement Part may be available (8D0-972-275).
