whenever i start the car, red temperature light comes on and starts beeping. this light is supposed to be blue when engine's cold, right? beeping goes away after a few beeps, but the light continues to flash for the next few minutes, then eventually goes away.

this used to be a once a week thing, but now it's every time i start the car.

what's wrong with my car?!?! please help.

bad coolant temperature sensor

bad coolant temperature sensor

is this an easy fix? if so, what do i need and how much would it cost? thank you very much.

I have had this same problem with my 2000 beetle. I replaced the ect sensor and the result did not change. However, after I replaced the water pump the problem went away. Also, remember to replace the timing belt at the same time

A new coolant temp sensor is not expensive - maybe $AUD40 and clips into the coolant hose near the air cleaner. Change that and hope the rest is OK.

Depending on the exact symptoms, this thread may help too. May not be a bad sensor.
