    What do my fault codes mean!?

    01441 - i believe is the fuel level sensor, the car runs okay untill theres not much diesel left in the tank then the coil light comes on intermitently and some times takes a while to start. I do not have these issues when theres plenty of fuel in. Whats the usual fix for this ?

    00546 and 00532 im unsure what these are ?

    00546 - Data Wiring faulty

    00546 - Data Wiring faulty: Implausible Signal

    Possible Symptoms

    • Engine not starting / immediate Shutdown
    • Malfunction Indicator Light (MIL) ON
    Possible Causes

    • Wiring and/or Connector(s) from/to Immobilizer Control Module (J362) faulty
      • No Signal or Implausible Signal on W-Line between Immobilizer Control Module (J362) and Engine Control Unit or Fuel Cut-Off Valve Control Unit
    • Immobilizer Control Module (J362) incorrectly coded
    • Immobilizer Control Module (J362) faulty
    Possible Solutions

    • Check Wiring and/or Connector(s) from/to Immobilizer Control Module (J362)
    • Check Immobilizer Control Module (J362) Coding, Baud Rate Setting
    • Check/Replace Immobilizer Control Module (J362)
    Special Notes

    • Under certain circumstances this code may be stored after improperly operating the Vehicle/Ignition. For example after the Engine has stopped the Ignition is switched on again immediately (Engine Control Module is still in the Start-Up Phase).
      • In such a case switch off the Ignition and wait at least 10 seconds before switching it back on. Then check and clear Fault Codes.
    00532 - Supply Voltage B+

    00532 - Supply Voltage B+: Signal too Low

    Possible Causes

    • Wiring/Connectors from/to Control Module faulty
    • Power Supply (Battery/Generator) faulty
    Possible Solutions

    • Check/Repair Wiring/Connectors from/to Control Module
    • Check Power Supply (Battery/Generator)
    Special Notes

    • When found in an individual control module, it's most likely a local source (e.g. wiring/connectors).
    • When found in multiple control modules at the same time, it's most likely a common source (e.g. ground spot, battery, generator).
    • Intermittent codes are often stored during low outside temperature when the battery capacity goes down and may be ignored.
    • Common with 16946/P0562/001378 - System Voltage: Too Low stored in other control modules.

    Perhaps the level sensor in the tanks a bit worn and gets intermittant when fuel is low?

    How low are you running it anyway?
