what is obd 2 code P2181, in a 2003 vw jetta 2.o? would be very appreciated

This code is for cooling system performance. It generally means that the vehicle has a bad or leaking thermostat. If the vehicle does not warm up quickly enough to go into closed loop operation within the time programmed into the engine control module, it will set this code. It is generally cured by replacing the thermostat. If this is not the problem then you will need a scan tool to check the coolant temp sensor.

Good luck,
