Red flashing light on temp gauge

[M2TTJ]

Hello all, thought i would post my own thread, here goes....

This morning i started the car, it beeped a few times and the red light (which i have never seen before) flashed on the temp gauge.

I run it for about 2 miles, checked the oil, water and all was ok.
I started the engine again and the light didn't flash.

Am i right in thinking this could be a water pump issue as well or maybe a sensor?

It had been parked on a slight hill so i thought that the oil pickup pipe in the sump may not have been near the oil but this was long shot.

Any advice before i have to take the car tothe dealer would be appreciated.

Many thank you's.

mine does this alllll the time...mines just a faulty sensor on the coolant tank and I havent bothered to replace it as it doesnt do it all the time. Sounds like yours could be the same?

Great. I will ask them to look when it goes in for a service.
Thanks for the reply.

check the temp sensor give it a clean if not replace it. check the coolant as well

You need to check your water level first thing on a morning after the engine has cooled right down. Your level is probably just below min. Running it for 2 miles will cause the water to expand slightly and be above the min line.

I have a tiny leak in my coolant which I need to top up every few months. The flashing light comes on only on a morning when it is cold. Even after I've been at work all day it won't come on. Next morning it will.

get the car warmed up then drive steadily at around 70 in top gear, watch the temp sensor. if it rises its the pump.
