Some questions regarding my Leon...

[Charly]

Good evening everyone,

I own a 2020 SEAT León Cupra with approximately 72,000 miles, and I would appreciate your advice regarding a couple of issues I’ve noticed.

Firstly, I’ve observed that the air conditioning system takes quite some time to cool down and rarely reaches the set temperature. Additionally, the start-stop system switches the engine off even when the desired cabin temperature has not been achieved. While I understand this behavior can be normal, I would expect it to remain active until the target temperature is reached. During the last scheduled maintenance, I was informed that there were no leaks in the coolant system. What could be causing this issue?

Secondly, I occasionally experience a problem with the infotainment system. When I start the car, it remains stuck on the messages “Initializing Vehicle” and “Initializing Full Link,” and does not proceed further. The only way to resolve it is by performing a manual reset using the power button. Does anyone know what might be causing this?
Thank you in advance for your support, and I hope you’re all doing well.

If you press the setup button circled below - you can change how strongly it tries to achieve the desired temperature. Try changing it - and see if that improves the cooling?

Additionally, Your AC system is not hermetically sealed like a fridge. The refrigerant can slowly leak out - at a certain point reducing its cooling ability.
If it's never had a regas at 6 years old, I would check for fault codes and give it an AC regas.
