Hello everyone,

I would like to give feedback to this topic:

https://www.briskoda.net/forums/topic/534598-overheating-problem-skoda-superb-year-2018/

Brothers from the Skoda Superb Facebook group in Turkey solved my problem.

The problem was the lower bumper grille shutters. They were stuck.

I removed the shutters, and now the coolant temperature no longer rises above 90°C under normal driving conditions. It reaches a maximum of 100°C when I drive at 230 km/h with an outside temperature of 26°C.

The oil temperature is still quite high, but I think this is either a different issue or simply normal for these cars.

Best regards

What type of actuator operates the shutters?

I dont know. I didnt removed the actuator

What's your oil temperature getting to at say 220-230km/h after 3-5 minutes of driving now that the shutters are removed?

My numbers (Mk3 Octavia CUNA TDI 184bhp) are about 107degC - 109degC at 200km/h, about 115degC - 117degC at 215km/h in ca 20degC environment, and I got to 125deg C on one occasion driving at 230km/h before I started watching oil temperature...

I try not to exceed 115degC, even though the engine can take more, the oil pump is belt driven ( and the belt is in the hot oil).

Hi, When I drive for about 10 minutes at 230 km/h, the oil temperature goes up to 137 °C with an outside temperature of 26 °C.

In my opinion, the oil temperature is still quite high when I compare it to my Passat B8 2017 with the same engine.

I also noticed that the ECU is reducing the speed when the oil temperature goes above 135 °C.

I think there is still an issue with the oil temperature, but I can live with the current situation because nobody drives at over 230 km/h for a long time with diesel prices these days.

On a normal drive between 150–180 km/h, the oil temperature does not exceed 120 °C. Based on the input I got from other forums and Facebook groups, the problem could be related to one of the following:

- Oil cooler

- Dirt in the radiators between the AC radiator and the coolant radiator, where the shutters were.

In the future, I will probably clean the radiators and change the oil cooler when I change my oil next time. I will give feedback if I make progress with these.
