Hello first of all, the same situation has been in my car for a while. Especially in the winter season when the vehicle's engine temperature is low, when I set off without heating the engine, there is a very hard transition sound from the first 2-5km gears, the engine's rpm changes officially :) and it gives a warning in written and audible form on the screen. When I stop the car safely in a safe place and start it again, the warning goes off the screen and at the same time the engine gets hot, I don't get any more errors until the engine cools down again during the day. I think that the gearbox oil cannot shift gears because it is cold. Frankly, I do not think this is a situation that I need to have it repaired, maybe I think I will not take it again when I change the gearbox oil during routine oil change. For those who have this problem, maybe I will share the change after the oil change.
