What's the 37de code MINI Cooper?

If You have a check engine light turn on in Your MINI Cooper I recommend that You pull over and get off the road as soon as possible to make sure that You do not cause damage to Your engine. Next You should connect an OBD II scan tool to read the code that is stored in the ECU. If You have a code 37DE that means that there was a fault detected with the crankcase ventilation heater control circuit. This system is designed to heat and remove vapors from Your crankcase and engine before they reach the atmosphere. If this system fails it means that there is an emissions problem and You will need to get it repaired.
