    From the Ross Tech wiki:-

    16514/P0130/000304 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit [h=4]Possible Causes[/h]
    • Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1 faulty
    [h=4]Possible Solutions[/h]
    • Check Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1

    17924/P1516/005398 - Intake Manifold Valve (N156): Open Circuit [h=4]Possible Causes[/h]
    • Wiring from/to Intake Manifold Valve (N156) faulty
    • Intake Manifold Valve (N156) faulty
    [h=4]Possible Solutions[/h]
    • Check/Replace Intake Manifold Valve (N156)
      • Perform Output Test.
      • Use Scope to check Activation Signal while performing an Output Test.

    18001/P1593/005523 - Altitude Adaptation: Signal Out of Tolerance [h=4]Possible Symptoms[/h]
    • Unknown
    [h=4]Commentary[/h]This is one of those fault codes where the ECU knows something is amiss, but cannot pinpoint the cause.
    [h=4]Possible Causes[/h]
    • MAF sensor (G70) out of tolerance.
    • Leak in intake system.
    • Throttle position sensors (G187/G188) out of tolerance.
    [h=4]Possible Solutions[/h]
    • Check MAF/replace MAF Sensor (G70).
    • Check intake systems for leaks and repair.
    • Check Throttle position sensors (G187/G188).

    18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low [h=4]Possible Causes[/h]
    • Cables on the Battery were removed
    • Battery weak (voltage)
    • Generator Disfunction
    [h=4]Possible Solutions[/h]
    • Check Battery Cables
    • Check/Replace Battery
    • Check/Replace Generator
    [h=4]Special Notes[/h]
    • If multiple Control Module have Power Supply Faults stored, it's most likely to be one common Problem like the ones shown above. Otherwise when only one or two Control Modules have such Codes stored you better start searching at the individual Power Supply of these Modules.
    • Terminal 30 means unswitched battery power that is supplied even when the ignition is off. This is not referring to any physical terminal numbered 30.

    Clear all codes, then check back after a couple of days to see what is active before diving into 'fixing' stuff
