Hi all. Just bought a 106 1.1 petrol (1999) as first car for my son (he loves it and so do I!)
Going through fixing all the small/large faults you might expect with an 18 year old car and this one has me flummaxed.
Should the yellow high temperature coolant warning light come on with the ignition on for a few seconds then go out? (like the airbag and engine management lights)
Our one does NOT come on at all. I thought it might be the bulb has failed but when I got the instrument binnacle out I found out it has non-replaceable LED lights.
Does that mean the LED light has failed or the light only ever comes on if it actually is too hot? If it's an LED fail can these be replaced individually?
The car does not have a temperature gauge so we are reliant on this warning light only.
Please could some one just turn their ignition on to see if they get the light?!

Cheers - Pasqual

It should illuminate when the key is turned.

For info... from what I have googled ...
the blue sensor turns on the overheat light at 120C

hi.

according users manual the key has 4 positions: S,A,M and D

S-ignition off
A- power to acessories and charging light on
M-ignition on and following lights on:eek:il pressure, charging,glow plugs (diesel),brake fluid level, engine check, abs and airbag.

Manual doesn't mention temperature on 2nd click position!!



How can I check if it is working??:confused::confused::mad:

and one more thing: I shorted the temp sensor to ground and the only thing it did was the fan started to work as soon as I turned the key.

I put the sensor plug agaid and I plugged an obd reader and let it idle until it reached 100ºC. in that moment the fan syarted to work but no signs of hi temp light!

Hi lammcl!

Your post make me re-check the 106 user's manual and I found a mistake in the portuguese version: is says the hi temperature light wont turn on at M position!!
on the other side the english version say that the light will turn on at M position!!

The high temp light WILL NOT come on when the fans come on it basically only comes on if engine is TOO hot fan coming on is not too hot thats still under the threshold.

Having said that i think the light should come on with ignition on during the self test phase of all the sensors doubt the bulb/led is faulty though more likely a broken wire somewhere or someone has deliberately broken the LED to make it stay out.

unfortunatelly I've discovered that the hi temp warning light is ok: water pump gone death...

in the meanwhile I found another odd thing: my radiator fan blown wind from inside to outside engine bay. it's wrong, isn't it??:confused::confused:
