e92 335i alarm issue?

hello,

i'm having this problem for like 2 months now, the car is 335i 2010 has only 31000KM on it (19375 miles).

and this problem appears,

when i try to unlock the car with keyfob the alarm will go off for about 15 seconds then the car will be dead electronically, like no light no seat adjusment, even the car key wont lock in its place when i try to insert it.
then after like 1 hour the electricity is back to the car and then its 50% 50% if its gonna work or do the same again if i try to unlock it.

i took it to the dealer and they replaced the whole alarm siren in the car, afterwards car runs with no issue for about 3 weeks and now its back again.

anybody heard or had this issue before?

100% battery is not the problem. the alarm somehow is locking down the car.

I would start by unplugging the alarm modules. The ultrasonic sensor in the overhead done light, the siren in the rear driver's side wheel well, and the hood sensor on the driver's side microfilter housing.

If the issues persist, it's not your alarm.

Something is hanging and drawing current when you turn off your car. You need to start pull fuses and parts to see where the draw is.

because when it happened the first time i had it towed to the dealership and they said the battery is fine nothing wrong with it (the car is only 3 years old) then they found an error code which they never experienced before in other beemers.

they replaced the whole alarm siren part in the car because it showed that there was a problem with it but the problem still in the car
