Hi Gaz, thank you for the suggestion. Since my Octavia is one of the latest of MKIII, I thought that it could be a different issue, so I started this thread. I understand that it is likely the very same of a lot of other users, so I will get back to my mechanic and see if a pump without the shroud could be a good idea or not. Should any of the forum moderators think that this thread can be closed, please kindly proceed. I will report the results in the main thread. Thanks to everyone for the support.

Hi, let me clarify. The gauge in the dashboard was going in the red zone and I had to switch off the engine to avoid damages. It is clearly not normal that an idling engine reaches temperatures over 115°C with the indicator near the red zone. Also the mechanic confirmed that the engine overheats abnormally. What I would like to understand is if the water pump replacement is the correct way to solve it, and reading J.R. comment I understand that if the sliding sleeve of the water pump doesn't retract I obtain this behavior. Thank you for your answers

Oh, sorry, I described it in the first post. Now I have also added it in my profile, thank you for pointing it out!

Thank you for the answer! Well, it is a problem, since the gauge went near the red zone while the engine was almost idling... The gauge in the dashboard remains at 90°C with the temperature read via OBD2 that moves between 80°C and 107°C. Moreover, the start and stop system dispalys an anomaly when the temperature is over 107°C saying "exercise temperature not reached". So, it is a problem. 🙂

Hi Everyone! During last holidays I went on 3000km trip and I faced issues with the engine cooling system. My Octavia is a 2019 1.6TDI with 142.000km. When starting with the engine cold, it seemed that having the air conditioning turned on made the coolant to go over 110°C. Checking with Torque, I saw the temperature rising up to 117°C then I turned off the engine and started again: the temperature return to a normal 90°C. This behavior appeared later also without using the air conditioning. According to my mechanic, I need to replace the water pump with the timing belt (since they have to be replaced together) and also the thermostatic system. I saw that there seems to be two different valves that open while the engine is warming. The first opens up at 71°C, making the temperature to lower to 67-68°C then rise again. The second opens up at 93-94°C, making the temperature to lower to 88°C then remaining around 88°C and 94°C, according to the road conditions. The last time I saw this behavior, it seems that the first valve didn't open. I parked the car with the coolant at 96°C, then turning to the max the heating system made the coolant to fastly go to 88°C. Could it be that it is not a matter of water pump but of some sensor or actuator? The money needed to replace timing belt and water pump are not so low and I suspect that it could not be the solution. Do you have any suggestion? Thank you very much!

Hi, I'm looking for an update for the infotainment system on my Octavia MKIII (2019). Attached to this post there's the screenshot took from the service menu. Is it sufficient? Thank you very much!
