Flashing/Beeping Temperature Gauge

Post by ukphiltr7 »

Recently, I have have had my temperature gauge flashing and beeping now and then. It is the top red segment that flashes when there is a beeping sound. I have checked the coolant level and all is OK and the beeping/flashing does not happen all the time.

Has anyone had this before on their C3 and is it the coolant sensor that needs to be replaced?

I had a similar thing on my C8. Changed the sensor several times. Turned out to be a loose connection on the sensor! Fixed that and no more trouble. If it's not there, it will be on another connection or earth.

You dont say what year it is or which engine is fitted but on most variations failure of the coolant temp sensors are common as muck. On the early models the part of the sensor that sits in the coolant was known to crack & worst case let coolant get into the wiring harness and ECU.

Thought it may be the sensor. The year is an 04 and the engine is 1.4 HDI.

Think I need to get it in and looked at as the last thing I want if the coolant to get into the wire and do more damage.
