Hi 

 

 

I own a 2007 Octavia II L&K (Laura in India). I am having a problem with high Engine Temperature form 7 days now

It does not happens all the time , I am not sure that it is the wrong sensor or anything else . Regulation of coolent is working fine ( I am sure because I checked it while running the engine ) . Fans also works normally though one time when Engine temp was high I noticed that fan was not running at the full speed when Engine is idle it starts and run for 7-8 sec then stops then runs after 10-15 sec.

It comes and goes and when temperature increases AC starts to give hot air (obvious) . My exteroir temperature reading is also faulty it give me 38°C even it's 20°C outide . It always give higher temperature in the range of 32- 50 °C. I am not sure but Engine temperature problem started to happens after few days of exteror temperature problem.  But both are different but do not know about that .

 

The thing is it does not happen all the time so it is hard to diagnose what's the real issue . Please help me about this .

Mine sits at 90* which I assume is normal as mine has always sat there (halfway on temp gauge)but obviously we don't get the high temps like your experiencing

Yup 90 is the normal temperature before having this issue temperatue reading does not goes over 90 . But now it does some time even I drive in heavy traffic it is at 90 AC works fine too . But sometimes it start to go over 90 then I have to turn off the AC (it helps but not much ) . If any of us having the issue let me know how did you fix the issue and what might causing this.

it might be worth getting the car hooked up with VCDS or simillar, assuming you can find someone in India. its possible that the coolant temperature  sensor for the ECU is not working properly and making the engine think its cooler than it really is. You'll need to look at 01-engine and the measuring blocks for coolant temp. IIRC the dashboard gauge and ECU use different sensors.

 

The external temperature sensor is behind the lower front bumper, but its only purpose is to display on the dashboard the outside temperature. Failure of this is common, and its easy to replace.

How do you know the engine temperature is high? Is the gauge going into the hot zone or are you actually getting a hot engine?

Both things are happening . I did get it to Skoda workshop and they told me that it is the fan issue . The Radiator have 2 fans they said big one is faulty when engine heats up it does not runs properly . As I mention that when ever heating problem comes up fans runs slowely for 4-5 sec then stops for 4-5 sec .

I know that this is the old thread but I am replying for the sake of others. I got that issue fixed .

Since it was winter in India Temperature does not flies over 90 so I thought issue is solved but as the winter is passing by the temperature came back . 

The problem was with the Radiator Fan. 

In the Radiator there are 2 fans . One is bigger than the other one . Seems like Big one control the small one , I have a friend who runs a garage only for VAG cars . He have one spare fan . He replaced it and it is working fine now.
