[Solved] Skoda Superb2 1.9TDi - The temperature indicator lights up after firing

From about 2 days after starting the car, the oil / coolant lamp lights up.


The indicator first peels and then flashes all the time. At the beginning I was shocked because I did not think that something like that could happen to me. Nothing at the car was done after the timing at the ASO about 2 months ago. I have a coolant level between min / max.

If I turn off the car, I will turn on again - sometimes the indicator will come on again, and sometimes it does not burn after restarting.
I also noticed that if the re-firing does not give anything and the control lights up all the time, it uses the moment of delay between firing and lighting the control, moving. Nothing happens then.

After all, there is a problem only I do not know where it lies and how to fix it.

What can you do?

1 add the liquid to the max and check if the cable at the sensor and the level sensor itself have not broken off.
2 connect the computer and see if it shows something.

Thank you very much for the answers! Problem solved, control for now and I hope that it will not ignite What I did?
I read your advice, analyzed the functioning of my car and set myself the task of removing the coolant tank first and cleaning it. If it does not help, I will go to a friend who has a computer and we will be able to advise what the machine will show.

Cleaning the tank with coolant was enough! The indicator light has not turned on anymore.

ps. I dismantled the tank, I put 0.5L of solvent, I added freshly boiled (slightly cooled) water and left it for 10 minutes. It was nice to see how the dirt was falling off. I rinsed the tank thoroughly, thawed / dried and re-mounted. I added the fresh amount of fluid I had previously released and started the car.

That's how I solved my problem.
