Drive cycles

Hi bjerzey,

To complete the driver cycles you must drive the car twenty miles and then shut the car off and allow it to cool overnight. Then drive the car another twenty miles and the monitors should be reset.

Please let us know if you need anything else to get the problem fixed.

Cheers

How long did you drive vehicle? How many days?

They say it could take up to a week of regular driving to set the drive cycles. If it will not set the drive cycles usual problem is bad thermostat or bad intake air temperature sensor.

If you have been driving it for that long there is definitely a problem. How the drive cycle works is the computer checks the outside ambient temperature and compares it to the engine cooling system temperature and it needs to see they are equal when a cold start condition occurs. I find most causes is a out of sync outside temperature sensor or engine coolant temperature sensor. The other problem is the computer may not have memory power and the computer keeps resetting. The power supplies will have to be checked.
