Skoda Fabia 2000 1.4 Comfort: Engine Temp Indicator Issue after Cold Start - Possible Causes?

Question

I have a Fabia 1.4 from 2000 comfort, after starting the car, the engine temperature indicator lights up, even though the engine is still cold, when the engine temperature rises a bit and I start the engine again, everything is OK. This malfunction occurred after a frosty night when the car was...

I do not remember exactly if this light came on, but when I had too little coolant in the equalizing tank, a light came on, probably because of the engine temperature and it was beeping 3 times. Check the instructions, maybe just add some liquid.

VAG to hand and first check for errors, then delete and see how to proceed.

Thanks for the quick reply. I'm just waiting for the interface, so maybe I'll be able to say more later
The simplest solutions are the best, but it turned out that there was not enough coolant in the expansion tank, which I had not noticed before. nom thank you very much.

Hello I am the owner of a fabi 1.4 mpi 68 KM. The temperature indicator has been acting weird lately. Please let me know where the temperature sensor is

temperature sensor see picture

rdcom · Answer

Thank you for the advice, but from the photo I can't figure out where this sensor is. When looking at the front engine, I can see 2 sensors, one next to the oil filter, the other one on the lower right next to the oil filter. When I move it next to the oil filter, the gauge shows the coolant temperature correctly.

jan_man · Answer

the reason for the lighting of the cooling indicator may be:
Oily expansion tank (ultrasonic sensor does not work)
poor electrical contact in connection with the temperature sensor located on the thermostat

Hello. I had the same problem and the contamination in the tank was rinsed out and the problem was gone. And as for the electrical cables, as some describe it, it is enough to shorten the cube at the tank to make sure whether the sensor is blown up or the installation. after shorting the pins, when the light goes out, the sensor must be replaced

I will step on the topic!
I have a problem with my factory I 1.9 SDI engine (2001). After replacing the thermostat (probably not immediately, but on the next day), the coolant temperature indicator stopped working. I replaced the sensor because I was sure it was his doing. Unfortunately the indicator was still dead. I shorted the contacts at the sensor for a short time - after switching on the ignition, the indicator swung halfway, but it fell down shortly (this was the case every time the ignition was turned on). The above would eliminate the sensor and indicator. Where else to look? Maybe someone knows how the connection of the sensor and the indicator works. I will be grateful for any help

Just add g12 fluid after the night, you have too low a level as the engine warms up, the level rises and it's ok.

Alternatively, you have a damaged head gasket and the oil gets into the cooling system, stays in the tank and contaminates the electrodes

I will also add my voice to the statement. I own a 2000 skoda Fabia comfort, 1.4mpi engine. A month ago I replaced the coolant reservoir and about a fortnight ago I picked it up from the mechanic and it had the following done: timing change, oil and filters, cleaning of the cooling system. My problem is that for the last three days it has started to get mega cold and my coolant light appears (squeaks and flashes) on a cold engine when I start the car, but when the car warms up and I turn it off and start it again, everything is fine. Does anyone have any idea what this could be?
Regards

A little over thirteen years ago, colleague @stefano11 in this topic gave a very likely cause. Have you checked the fluid level in that expansion tank you mentioned at all on a cold engine?

jsasanowicz17 · Answer

Yes, I checked the fluid level, it was too low 3 days ago, so I added it and it was quiet for a while, but yesterday the light started to come on again.

Additionally, on the model I have, the mechanic told me not to fix the head gasket because he had a customer with the same car, replaced the gasket and then had it replaced again a few months later because it's that type of car and nothing can be done about it. On the other hand, I'm curious if anyone else is having the same problem as me, or is the mechanic just bullshitting me and I'll have to bear the same costs again because he didn't want to mess around with replacing the gasket?
