    Do you know what the original code was? I'm guessing it was a P1255 or P1256 which are for engine coolant temp sensor short to ground or short open respectively. Either way you can fix it by replacing the little green ECT sensor with a new one. I'll need to know what engine your car has to tell you where it's located though.

It's just to the drivers side of the valve cover. Attached to the coolant flange under the hose for the PCV. In this pic if it works.

I posted on both these just in case someone finds it while searching.

Hi, could be the head gasket, have a compression test done to determine pressures etc, with the engine running see if you can smell exhaust fumes coming out of the radiator filler, good luck.

Need to fing location of ECT sensor on a 1.8L turbo 2004 jetta


Take off the two covers on top of your engine. The ECT sensor should be on your right side of the engine. It may be either black or green and has a 4 blade connector. There is a plastic clip you slide out to replace the sensor. Hope this helps. Only takes a few minutes to replace
