Flashing temperature light

Hi wondered if anyone can help

My garage recently changed my rocker cover lid and also my anti freeze. 

Ever since these have been done my temperature light constantly flashes. Is this just a coincidence or is it another problem.  It's not overheating and there's warm air coming from the heaters.  I've pulled the spade connectors off and on but that doesn't seem to help.  Sometimes it goes off if I stop and start the engine a few times

Any help


Regards

Is there is right amount of coolant in the car?
The light flashes to show low coolant and which spade connector are you removing?

if it has a level sensor in the top of your header tank unplug it and bridge the 2 pins. if that stops it remove the level sender and clean the tips of the pins. if not look at the wiring and level warning relay 42/43 above the fusebox, if you pull it out this will disable level warning but the temp gauge and overheat warning will still work fine

thanks for the responses. the water level os correct. i took all the spades off in and around the engine block, because wasn't sure which one connected to the temperature sensor!!

i have a GTI sportline 1992, would this have a level sender? have you a picture as to what this looks like?

yeah you'll have a level sender, its in the top of the header tank you cant miss it!

It should have a sensor, it's fitted to the top of the expansion tank (where you put the coolant in) it's has a black electrical plug on the end with 2 wires coming out. If' it's not there then someone has changed your tank.
I'll try and get a picture later tonight. 

Have you checked the earthing wire which attaches to the corner of the rocker cover, mine had a dodgy connection and when I fixed it, years of having a constantly flashing coolant light stopped!

Never knew why though

The sensor fits here.

thanks for all your help, ill get back to you on my findings!

It was the temperature sensor on the top
Of The water tank. I cleaned it like you said and all seems good now!

Thanks for everyone's input

Til the next time…..

The sensor on top of the water tank is for the coolant level, it does not read the temperature.
Glad it's stopped flashing.
