Special Notes

If found on a New Beetle, can be caused by the Insulation Displacement Crimp (IDC) terminals that are

used for the reader coil at T32a/2 and T32a/17 (green connector) that result in poor contact. This can

degrade the signal from the key.

This Fault Code can be stored in due to Remote Control or Immobilizer Problems. On most Models thesesystems 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 but cut out after 1-3 Seconds if

an Immobilizer related Problem is the cause. On models using Kessy Systems and Electronic Keys, mostsystems in the car won't power up at all if if an Immobilizer related Problem is the cause. If you are NOTexperiencing this behavior (e.g. Instrument Cluster powers 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 theWiring, an optimized Replacement Part may be available (8D0-972-275).

May be stored in Combination with 17978/P1570/005488 - Engine Start Blocked by Immobilizer in EngineControl Module.
