1.6 Ecoboost noisy idle

Hello everyone.
I find myself in need of some technical support, and I pray someone knows the cause of this problem, thus ending my sleepless nights.

There it goes :
New Ford Focus, 2013, bought with 7 miles on the odometer, brand new from the dealership.
Now it has 5000 ( 5k) miles on it.
The engine is an European turbocharged 1.6 Ecoboost, 180 hp, direct injection.
Eversince last winter, January, a strange noise has begun to be heard under the bonnet, (leaving aside the normal noise of the injectors)
The exact symptoms :

- the ticking irregular noise comes up ONLY when the engine is at idle and when the car has run at least for a few miles.
- when I start the engine and until it heats up, everything is perfect, nothing abnormal is heard, no clicks / ticks.
- the hotter the engine, the more present the sound is.
- when I barely press the throttle rising the RPM to around 800-900, the ticking sound stops. ( the present RPM at idle is around 750 )
- when I turn on all the lights and the AC, the tick tends to stop, also- it becomes hardly noticeable.
- a few months ago, when I turned all the lights on, the tick would increase!! Now it is exactly the opposite.
- the engine pulls hard, it goes like a rocket, the fuel consumption is extremely decent.
- no ticking sound when driving the car.

What I tried so far :
I changed the oil a few times together with the oil filter.
First I used the recommended Formula F 5w-30. No difference.

Second change : Castrol 5w-20, made for Ecoboost. Ticking increased a little . ( Low viscosity at working temperature?)

Third change : Valvoline 5w-30 C2, with a higher viscosity at working temperature. Ticking remains the same.

Went to 2 separate dealerships : `the sound is NORMAL and you need not worry !` - No s..t !??

PLEASE watch the video below and tell me what you think. Lifters? Bad oil?
I say again, the car is NEW and now it has 5000 miles on.
