Hi guys,

so I have a A4 B8 2.0 TDI in Manual, yesterday, I went into my car for something inside, I putted the keyfob in the ignition to start the AC, because it was smoking hot that day. Suddenly my radio turned off and I started getting light warnings on the dash (idk if it has to do something with this bcause lately I get them always, but the radio problem happened to me the first time), my dash went off, I took the keyfob out, tried to do it again, but the radio nor the dash came on, I realised light on the car (blinkers, license plate light, daylight, etc.) started blinking randomly.. I tried to lock the car via the central (I thought maybe alarm went off or something) but It didn't lock.. I putted the keyfob in the ignition to try to start it again, but it didn't start, also I couldn't get the keyfob out from that moment, I noticed strange clicking in the right rear side from the trunk, and also lights on the middle console( media, radio controlls) started blinking with the same rate as the clicking, so it's somehow connected together, I would say? ... so, I think it's a dead battery propably, I don't have a lot of experience with the car, I bought it recently so I'm not already familiar with it's flaws, probkems, etc.

So as my central locking isn't working, it means my car is unlocked and keyfob is in the ignition and I'm parking in front of my ​​flat... not a good situation I would say .. I'm checking the car every hour if it's still there and can't sleep currently because I'm mad paranoic .. but seriously..

Can anyone give me any advice what could it be and how can I resolve it? Or at least, how can i lock the car somehow so I can atleast sleep well?

Thanks guys and have a nice day
