The radiator fan continuing after car stops. This happens after a small journey. Quite a loud sound or maybe is it something to do with a/c?

I own a Skoda Octavia and, since its 12000 miles, the engine loses power when overtaking a car. The flowmeter and the turbo's pressure valve as well as its unions have been changed, but the car keeps losing power. The turbo is about to be replaced. There are many interior noises as well which are certainly annoying.

When battery is connected all light coming only the glow light not showing in the cluster but not starting only cracking noise coming

Si accende spia motore e esc la macchina va a strattoni ,poi funziona dopo che sta ferma.

Gearbox clunk when I shift into Reverse, and it upshifts too early—it’s already in 4th gear while I’m only doing 20 km/h. "

As the title implies the back window stopped working and now wont go down, before it stopped, the closing mechanism of the door was malfunctioning, as in it was activating when i was opening it by pulling the door handle and as it swing open there was the clicking sound you wold hear when pressing the open/close button on the car key. Now the clicking stopped but the window won’t open.

When i reach 140 km the car start to make high sound from gear box i think and the rpm reach 5 and 6 and didn't speed more than 140 km/h i think it's a problem between 5 and 6 in gear box

AC blower motor working with noise and stops after few minutes of running

I've just had my gearbox repaired by a Skoda dealer in Cartagena, Spain. They had to replace the sensors. Since then, I have had lots of electrical problems.
Airbag light on
Cruise Control is intermittent
Indicators sound different
Reversing sensors not working
Could they be related to the repair?

Recurring problem of Battery drain within days, even with solar charger attached. (Batteries etc have been checked and no problem there.) Air con is weird, blowing cool from one spot and heat from another. Blower sounds strong but not much heat on the feet for example. Central locking does not operate properly. The problems began to accumulate following visits to workshops ... All fine before then.
The vehicle has a factory-fitted alarm.
