The PDI does include checking everything you mentioned but a comprehensive check if often not possible for the reason mentioned below.
Things can go wrong in between PDI and delivery as well; so that's your final checkpoint.
Also, I have booked the new facelifted EcoSport Titanium+ AT which comes with lots of electronics and sensors. Is it advisable to check each and every feature of the car which I think would take hours?
You can try if the SA allows you but in a majority of the cases, the SA will show you the car only externally. If you strike a good rapport with him, he will perhaps allow you to open the car and turn on the ignition. But I seriously doubt if anyone will allow you to turn on the engine/drive the car. At times, the battery is disconnected. More often than not, SAs don't have the key of the car when they take you for PDI.
