Hey guys.
Só I've changed the battery to the new one and did a BSI reset procedure, though I don't know if there's a way of knowing if the reset was successful.
Everything is working I guess. The only thing I noticed is the tyres pressure sensors are not reading anything. But I'll see tomorrow while driving if the sensors have any change.
Thank you all for helping a guy out. I appreciate it.

As said before its not a good idea to jump start modern cars but sometimes its needed to get the car going for work etc. If your ever giving a car a jump start in the future, put your lights, rear heated window and other power hungry devices, then connect to the car to be jumped. After you've jump started the other car, individually put the power hungry devices off, this reduces the chance of any power surge damaging the delicate electronics in modern car
You've got this the wrong way round.
Jump start as normal, switch the power hungry devices ON before disconnecting the jump leads.
When the charging car is connected, the alternator on the dead vehicle sees 13.8v of a healthy battery. When you disconnect the charging car, the alternator sees the low voltage of the dead car and bumps up the charging rate. This is where the spike comes from. Put on the power hungry devices to absorb this spike.
Like in the pre-electronic days. If you hadn't got jump leads, nick your mates battery, take yours off, connect his, start the car, turn everything in sight on, remove his battery and refit yours.....Possibly not a good idea these days!!

Notice the BX is still top the list but sadly gone

My son came home from work last week and told me thats exactly what they had done. I was easier to do that as they never had the radio code or something and they had to fit a new battery.
I remember back in the day (mid 80s) reversing the polarity of the battery when jumping starting as long as one of the batteries was low on power. I wouldn't want to try that with 2 fully charged batteries.

You'll have to explain that one to me, please. I've never heard of this.

Yes, it's technically possible to charge a battery the wrong way.
If one of the batteries is virtually dead, you don't get much of a spark when you put the jump leads on the wrong way around (don't even ASK how I know this!!!) and the dead battery will charge up with the polarity reversed. If you're not paying attention, or if you have a colour blind assistant, the first you know about this is the BIG spark when you connect it to the car.
Then, with moderns, you usually find it will crank, but not start and none of the dash works.
If you're extremely lucky, the alternator fuse will have popped quickly enough to save the electronics. If not, expensive silicone will have become an unpleasant aroma and quite possibly written off the car.
Going back to the days of rubber cased batteries, it wasn't unusual to deliberately reverse charge a battery, to crudely desulphate it and get another few months use out of it.
Definitely not recommended nowadays!
My old pal had a Hyundai Pony, one morning the battery was flat and he pushed it to try to start it, unsuccessfully, he was stuck until the vicar came along with jump leads to 'help' they connected the leads wrong and there was a blue flash.....that's when I got called out.
He had to wait four days for a new fusible link to arrive, the dealer said he'd never seen or had to order one before.
