I have a 1990 BMW735i that has a serious battery draw. If the car is not used for 3 or 4 days the battery will be completely dead. I had this car imported to Canada from Japan in Feb 2007. It had 34,500km on it and it now has 42,000km. When I first got the car it had this problem . Thinking the battery wasn't holding a charge I installed a new one. It did not help. The other day I put an ohm meter on the battery and with everything shut off it is drawing .16 amp. I pulled all the fuses and relays with not change to the amount of draw on the battery. When I pulled the LKM it dropped to .08 amps and when I pulled the CCM it dropped to .01 amps. Is it possible that the CCM is the problem? If anyone knows of any other thing it could be I would surely appreciate hearing from you . Thank you very much for your time.
