Hi guys!

Since a couple months I'm a happy owner of i30N. For quite some time I've been getting this beeping while starting the car. It does it almost every time. It's 10/15 loud beeps and there's nothing on the dash. I checked everyting but I can't find the reason why it does that. Maybe someone experienced the same problem?
 
Does it go away on its own or do you just start driving? Only thing that comes to mind would be something of moderate/light weight on the passenger seat and the seat-belt reminder is triggered; but that should show a light on the dash. (quick check would be to engage the seat-belt and see if the alarm stops.) You do have yours buckled before driving, don't you?
 
Yes I have my seatbelt buckled and there is nothing on the seats. Also the beep is not the same as the beeping of the not buckled seatbelts. It's louder and high pitch. I have a vido of this but i can't attach it here
 
Try buckling the "empty" passenger-side seat belt - it's weird but so is your issue. (I believe the parking/e-brake is different sound but that should only trigger if your trying to drive the vehicle.) Assume there's no chance it's one of the parking sensors detecting an object/person near the vehicle; there should be a visual also and I haven't had it stop until the detection clears.
 
Do a test and change the key fob battery. I had something similar once, cannot exactly remember, but when I got in the car, the bips started, different bips from the ones that I knew, it was a low key battery warning. The thing is, the message was displayed for a short time, if you were not paying attention to the cluster, you would miss it.
 
You need to change the permissions for us to view your vid btw.

but I'll second a guess that it's fob battery - had something similar in December; whole bunch of unexpected beeps & it was the low battery warning for the fob.
 
Hey gyus I'm coming with an update.
So two days ago I was driving my car, I stopped at a gas station to get something to drink and when I wanted to start my car I couldn't. It was dead. The emergency lights were working and the screen on my dash was shownig that the doors were open but the system and all the other things were dead. So I called the assistance and now the car is in the garage.

I think I have a aftermarket immobiliser I don't konw for sure because I'm the 2nd owner of the car, but I have this black kind of remote with my keys and it has one button and this nob that you can plug in somewhere.
 
See post 10 - from your post 11 response it sounds like you have an aftermarket immobilizer. Is the vehicle able to start/run now? If not try a replacement battery in the newly mentioned "black kind of remote". Contact the seller and get details on how it works; or look up details on internet if it has a brand & model number. Good luck (Next time give us the full story in your first post.)
 
Of the immobiliser remote that I had with my keys (post 11). Erlier (post 7 adn 8) it was the key battery, but it didint solved it. Changing the immobiliser remote battery solved the issue
