[Gasa]

What does this symbol represent, the temperature of what.

Water temperature pre-warning lamp.
"If it lights up slow down."

[Gasa]

...yes it lit up for a few seconds, I tried it on a short part of the road to see what speed it could reach, it showed 190 km/h and for a moment that notification lit up.

[Dieselman]

That's a pretty healthy speed for an atmo diesel., even allowing for spedometer inaccuracy.

[Gasa]

Yes, it reached the speed as the factory declares, next time I will use the GPS to check the exact speed.

[Gasa]

These days I went to check and refill the air conditioner, for now the weather is bad and there is no need to use it, I still don't know how it cools, if it is strong and meets the needs in high heat.

Those pressures look perfect - did you have to add much gas?

[Gasa]

..yes, there were about 90-100 grams of freon in the system, according to the table, there should be 800 grams in the system.

[Gasa]

...what could be the problem that sometimes occurs, that when idling it increases the speed of the engine to 1000-1100 rpm.
from where it receives the command to increase engine speed.

[Dieselman]

Is that at the point the A/c is switched on?

That actually sounds like the cold start fast idle speed, so check the coolant sensor.
