    yesterday, while i was driving control ligh for motor switch on,
    with signal beep, on display was message: Antipollution fault.
    It seems to me car doesnt have full power and temperature
    indicator is on 90 Celsius.
    I plain to go to service this afternoon, car is still under warranty.

    For information, my 306 sits around 90 degrees during normal driving.

    Often when an engine fault is detected the car will switch into a "Safe
    mode" which limits power etc, but is designed to get you home/to the
    garage whilst running within additional limits designed to reduce any
    further issues to the engine.

    Antipollution fault sound like it's something to do with the emissions
    of the engine, so maybe a sensor has failed or something. The
    dealer/garage should be able to diagnose the fault and get it fixed as
    it's under warranty.

  3. One of the many sensors has either gone closed/open circuit or reported a
    value out of it's normal range. In fact, if you unplug any of the sensors on
    the engine, including fuel injectors and run the car, it'll report:
    "Antipollution fault" It just seems to be a catch all error code. You'll
    have to read the diag code from the ECU to find out which of the many
    sensors has reported a fault.

    If you can - ask the tech for the fault code, and what they did to repair
    the vehicle and prevent the fault from reoccurring. Any response along the
    lines of "We've reset the ECU and that's fixed it" will almost certainly
    mean another trip back to the dealer, and you don't want that outside of the
    warranty. (Seriously, the Siemens / Bosch parts on these engines are not
