OBD code P1255

Hi,
I have a 2000 new beetle 2.0 gls.
The check light is on since few days...
I went to Autozone and the code is P1255???
Is anybody familiar with this code?
Thanks for any help...
vtec-inside81

That code is for a faulty ECT engine coolant temp sensor. They are all prone to failure. They are about 8$ in parts and takes about 20min to replace. Its on the driver side of engine on the coolant hose. THe new sensor is green and the old one is black.

Thanks,
I will replace it asap.
Do I need any tool to switch off the light???
