Hi,

i been having an isuue with my car batery all of the sudden i am ready to leave to work and want to start up the enginge and surprise death battery! i have noticed that when i turn off the car the ac woun't turn off the lights are off but air still coming off when the car is copletally off do you think the ac is the one causing the isuue with the battery? i have checked the battery and it is in good staning something is causing it to go death or do you know if this issue can be involbed with a sensor or any other electrical piece? and just one last thing do you think that batery issue had something to do with my keyless remote control has disprogramed?
for what i know some contols of several cars can be reprogramed with out have to go to the dealership, do you know if on this car model ho the control can be reprogramed?

i really apreciate your help and information,

Thanks a lot.

The air flow through the vents after the key is off is due to the fan motors final stage failure. Replace the final stage with part# 64-11-8-385-549, this module is installed in the air stream in the heater box and you will need to remove the glove box and carpet trim to gain access . As to the key failure, the key(s) need to be reinitialized. Procedure is as follows, get in the drivers seat and close the door, put the key in the ignition and turn it to the KL-15 position (key on but do not start) then turn the key off and remove it, then hold the unlock button down while you push the lock button three times, the door locks should all then lock and then unlock, repeat the procedure with the second key and you should have keyless entry function again.

hi i in the keylees programing i trye a lot times but don t work do you know others steps to programin?

You may have another issue in the central locking if the keys will not initialize. Seek out a local BMW expert.
