  1. It sounds like the coil packs or spark plugs are failing under load.

    You will need to replace the coil packs with QUALITY replacement parts and also the Spark Plugs will need to be set to the precise gaps and torque to the correct setting, otherwise the fault will continue in the future.

     

  2. Hi.....welcome to the Forum

    If it has a turbocharged engine then sometimes the variable vanes become gummed up with carbon through lack of revs to keep everything clean and moving.
    You can buy a cleaner to run through the turbo to clean it up and a good blast helps to shift the carbon.

    Also, it could be an Air Mass Meter (MAF sensor) fault which is causing the loss of power.

    A scan of the fault code memory should reveal some more information as to what is going on

  3. Hi....welcome to the forum

    The easiest way to check glow plugs is with a multimeter and check the resistance of each one, they should all be roughly the same.

    The one with a different resistance is probably the faulty one

     

  4. Hi .... welcome to the forum

    It would certainly need a power supply from the reverse light bulb to make it live when reverse is selected but without seeing a circuit diagram to know whether this is enough to communicate with the display (e.g. bluetooth connection ?) 

    Let us know how you get on with it

  5. There would be two lambdas, one for upstream and other downstream of the cat.
    The upstream one calculates the fuel mix and the downstream one reads the efficiency through the cat and feeds back accordingly

    Hopefully the replacement CTS will do the job

  6. Hi....welcome to the Forum

    I would start with the coolant temperature sensor which is normally located on the top of the engine near to the thermostat housing area and within the cylinder head.
    Firstly I would check the plug going to it isn't broken or corroded.

    The cooling fan switch should only run the cooling fan and not provide any feedback to the gauge.

    The thermostat shouldn't be an issue regarding the fan starting up from cold and also the gauge but its worth checking that all coolant hoses are similar temperature when running.

    Let us know what you find

  7. Hi....welcome to the Forum

    Sounds like the system has lost its memory

    P2102

    Featured snippet from the web

    OBD II Fault Code

    The throttle motor is controlled by the engine computer (PCM). If the PCM does not see the requested movement from the throttle motor, code P2102 will set. The PCM may also put the engine into "limp home mode", limiting the available power from the engine to prevent unwanted acceleration.

    I would ensure the fuse is securely located in position and the battery is fully charged and then try turning it over with the throttle pedal moving up and down smoothly to relearn the settings
