Flashing Red Engine Temp on Start-up

[bub]

I've had this happen a few times now.

When the engine is started cold, the blue engine temp light comes on (normal) but within a few seconds it goes to a red flashing temp indicator with chiming sound. After a few seconds it will stop (going back to blue or going off entirely).

The VAG-COM shows no fault codes, and the coolant level appears to be normal.

Any ideas on what this might be? Coolant temp sensor going or gone bad? Wiring issue at sensor?

Do you have the green top sensor? If not, might want to replace it--DIY for under $10.

I looked today, and the connector is black, the sensor is black, but the cir-clip retaining the sensor is green. Is this green cir-clip what you are referring to?
