Last night, I put fuse 136 back in and left 110 out. Got the high battery drain warning this morning.... When I got to work, I swapped the fuses so now110 is in and 136 is out. The car should be sitting for about 10hrs... I'll see what happen when i get out later...

Don't know, just know it's an AGM battery

If some module keeps waking the car up, the phone/bluetooth stuff gets woken up with that-
they may NOT be the culprit in the drain. Your pulling the fuse just keeps them from waking up- but it may indeed be something else that is triggering things. newtis.info there should be some docs on how to diagnose parasitic drain... |

ok with fuse 110 in and 136 out, I don't have the high battery drain warning. I need to know where power to 136 is coming from and where it is going to....

I'm not familiar with BMW symbology on their wiring diagram. I need to find out what are the condition for that contact to close, (My guess it's a relay)

I don't have combox, I have TCU, I checked the relay that feed F136 and work fine on the bench. I also noticed that X1 on that relay is powered with the car off. I need to check tonight when I get home with the door locked,and trunk closed if that relay is still energized. I cannot find what in the junction box is feeding X1 on that relay...
