Battery Drain - All Fuses Out , still drain
Hi guys,
2010 535xi, all fuses out from the rear and front panel, relays, wire harness plugs and still draining .140 to .280mA where it should be below .50mA. What else should I do ? My last parts to remove and test would be: 1. DME computer harnesses 2. Starter 3. Alternator Interesting enough when I pull the positive thick wire from the battery that goes into the rear fuse panel everything goes to 0.00 draw. Is that right ? what does it really mean ? Where does the other positive wire go ? There is another red wire from the rear fuse panel that goes to the front I believe but I didn't see a way to disconnect it, even after removing that plastic white cover..some of weird screw... Please help as I am not very familiar with going this car and my first power drain and it`s very bad .. I been delaying this it for too long. |

Removed the DME and it's still the same thing.
Disconnected the positive cable from the front jump start terminal which I believe goes to either the starter or the alternator but again it doesn't seem to do anything. At this point I expect the Power Distribution module in the rear with all the fuses.. how can I test to confirm ? Remove all the fuses from the rear , connectors I guess right ? There is a red cable in there with some special cover ..how do I remove that and where does it go ? |

Thanks everyone, it's fixed. Someone tapped into that red power wire and found it , remove it , unfortunately I started from the front and removed the chair and a lot of other things. I measured resistance with ground and it was high about 7.5 ohms, way to high. Thanks everyone for helping out with this, feels so great even tho I spend 20 + hours I saved big bucks and learned a lot. Sorry for my "french" I was very pissed off to find it there...
