    I have a 2006 Jetta TDI that has a P1570 Error code. I have disconnected the battery, tried both Keys, reset the codes and still the same issue. Any ideas as to whats next to do?

    Thanks
    Ken

    VAG Error Code: 17978/005488/6260/5523

    EOBD II Error Code: P1570

    Fault Location:
    Engine Start Blocked by Immobilizer - Intermittent

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Immobilizer Warning Lamp ON.
    Engine starting but stalling immediately.

    Key(s) not matched.
    Instrument Cluster not matched.
    Engine Control Module (ECM) not matched.
    Engine Control Module (ECM) Power Supply faulty.

    Possible Solutions:
    Check for Fault Codes in Immobilizer itself (part of Instrument Cluster in many cars, but separate Immobilizer Control Module in some).
    Check Immobilizer Measuring Value Blocks (MVB) (usually in Instrument Cluster or Immobilizer Control Module).
    Match Key(s)/Instrument Cluster/Electronic Control Unit (ECU).
    Check Engine Control Module (ECM) Power Supply (Relay).

    Special Notes:
    In case of Engine Starting Issues please make sure that you are really experience an Immobilizer related Problem! Even if the Immobilizer engages, the Engine will still start fine but cut out after 2-3 Seconds. If you are NOT experiencing this behaviour (e.g. Engine doesn't start at all) your Problem is very likely NOT Immobilizer related.
    May be stored in Combination with 01176 - Key: Signal too Low in Immobilizer Control Module.
    If no other immobilizer related fault codes are stored and the immobilizer related measuring blocks are fine except Engine Start not allowed, in rare occasions it helps to try cold-booting the car. Remove both battery cables from the battery. Short the battery cables together (away from the battery) for about 15 seconds. Reconnect the battery. (Example.)
    Low battery voltage (including a faulty battery) may cause Immobilizer system malfunctions and testing should be done only with a known good battery installed.
