Having changed the engine battery the dash clock reset it self fromm 00.00. Quick search including Renault owners sites said either press the button on the end of the stalk, not got any, or through the radio settings, not original and did not reset the dash clock. At the MoT test station the tester said your clocks wrong, press the trip button and hold it until the clock flash and then press again to advance it to correct time. It works - Every day a school day.
