    hello folks,

    It seems my car has found out i was thinking of selling it and has decided to spew out some Fault Codes.

    Could any of you fine people please give me an explanation of what the codes are and what the probable faults would be?

    Codes as follows:

    18010
    17522
    17526
    01279

    thanks in advance

    (just realised i posted this in the 8P forum by accident! it was 7:30 am i'm allowed)

    18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low
    Possible Causes

    * Cables on the Battery were removed
    * Battery weak (voltage)
    * Generator Disfunction

    Possible Solutions

    * Check Battery Cables
    * Check/Replace Battery
    * Check/Replace Generator

    Special Notes

    * 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.

    Can't find a reference for this one

    17526/P1118/004376 - Oxygen (Lambda) Sensor Heating; B1 S2: Open Circuit
    Possible Symptoms

    * Malfunction Indicator Light (MIL) faulty

    Possible Causes

    * Wiring/Connectors from/to Oxygen (Lambda) Sensor Bank 1 Sensor 2 Heating faulty
    * Oxygen (Lambda) Sensor Bank 1 Sensor 2 Heating Circuit faulty

    Possible Solutions

    * Check Wiring/Connectors from/to Oxygen (Lambda) Sensor Bank 1 Sensor 2 Heating
    * Check Oxygen (Lambda) Sensor Bank 1 Sensor 2 Heating Circuit

    01279 - Longitudinal Acceleration Sensor (G251)
    01279 - Longitudinal Acceleration Sensor (G251): Implausible Signal
    Possible Symptoms

    * Malfunction Indicator Lamp (MIL) active

    Possible Causes

    * Longitudinal Acceleration Sensor (G251) Calibration not performed
    * Wiring/Connectors from/to Longitudinal Acceleration Sensor (G251) faulty

    Possible Solutions

    * Check Longitudinal Acceleration Sensor (G251)
    o Use Measuring Value Blocks (MVB) to check Sensor Signal for plausibility
    o Check Installation Position of Longitudinal Acceleration Sensor (G251)
    * Perform Longitudinal Acceleration Sensor (G251) Calibration
    o See Vehicle specific Diagnostic Procedures
    * Check Wiring/Connectors from/to Longitudinal Acceleration Sensor (G251)


    01279 - Longitudinal Acceleration Sensor (G251): No or Incorrect Basic Setting / Adaptation
    Possible Causes

    * Longitudinal Acceleration Sensor (G251) Basic Setting lost/not performed

    Possible Solutions

    * Perform Longitudinal Acceleration Sensor (G251) Basic Setting
    o See Vehicle specific Diagnostic Procedures for Details

    I have a fault code 01279 Longitudinal acceleration sensor too. this could also be linked to my airbag fault code of 65535 (aparantly).
    so my question is....what and where is the Longitudingal Acceleration Sensor?
