I had it on Vagcom today and this is what I got


Engine: 2 Faults Found:
 
18010 - Power Supply Terminal 30
      P1602 - 35-10 - Voltage too Low - Intermittent  (Possibly)
17978 - Engine Start Blocked by Immobilizer
      P1570 - 35-00 -                                     (More probably)
 
Repair Info: - (ONE)
17978/P1570/005488 - Engine Start Blocked by Immobilizer
Possible Symptoms
                 Engine starting but stalling immediately
Possible Causes
             Key(s) not matched
             Instrument Cluster not matched
             Engine Control Unit (ECU) not matched
             Engine Control Unit (ECU) 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 Values (usually in Instrument Cluster OR Immobilizer Control Module)
             Match Key(s)/Instrument Cluster/Engine Control Unit (ECU)
             Check Engine Control Unit (ECU) 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 behavior (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 meas. 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
 
Repair Info: - (TWO)
01176 - Key: Signal too Low Possible Symptoms
             Malfunction Indicator Light (KEY) ON
Possible Causes
             Immobilizer
                   Wiring and/or Connector(s) from/to Immobilizer Reader Coil faulty
                   Immobilizer Reader Coil faulty
                   Immobilizer Transponder in Key faulty OR incorrect Transponder in Key
             Remote Control
                   Remote Control Battery low
                   Remote Control faulty OR incorrect Remote Control used
Possible Solutions
             Immobilizer
                   Check Wiring and/or Connector(s) from/to Immobilizer Reader Coil
                   Check Key Immobilizer Transponder Status
                          See Measuring Value Blocks (MVB)
                   Check/Renew Immobilizer Key Matching
                   Check/Replace Key
             Remote Control
                   Check/Replace Remote Control Battery
                   Check/Replace Remote Control
