Hi can any one help i have a Volkswagon lupo that when it reaches approximately 82c water temp the emissions go from the correct levels to CO 8.61 HC 720 02 0.08 lambda 0.75. The lambda sensor is operating correctly in that it indicates a rich mixture.when the vehicle initially appeared fault codes indicating injectors short circuit or open circuit were recorded they have been cleared but the problem is still present but no fault codes are present. The ECU has been checked with no fault found thanks for looking
