Hi Guys,

I've been searching a lot around, but find nothing related to this.

MY BMW E90 2009 came with no USB in armrest (only in glove box) Bluetooth calling, but no audio, and with SOS assist function. Since i bought it used the assist function and connected drive services are already expired. i did not bother to renew them.

After a lot of searching and hard work and coding i changed my TCU to the combox to get USB in armrest and Bluetooth Audio. Also installed an aftermarket alarm system, after somebody tried cutting my door handles to get in my car and steal it.

The problem is this, somewhere there seems to be something wrong, cos if i don't use my car for more than 10 days to 2 weeks, then when i come back and open the doors, it gets connected and call immediately to the emergency services and i hear someone speaking through the speakers and asking me if i am ok. I say its a wrong call because of disconnected battery of my kids pushed the button. Its slowly getting annoying

I also notice that the date/day and the Km left to tank empty are all reset to zero ( battery drain)?

Any clue or suggestions why this would be happening.

Cheers

disconnect all wires from combox except MOST, power, ground, mic, aux (if you wired it), this will keep these functions work and disable e-call

For how long ?

when do i connect them back?

Do you mean when i don't use my car for longer than 2 weeks?

this will ensure that you wouldn't burn any circuit
