The reason this happened is because the 'Power distribution box' has 2 plates connecting right at this exact point! If you as much as loosen the nut on this bolt, the . Following an ongoing quality analysis at BMW, it has been determined that the plug-in contact of the positive battery cable on the front power distribution box can become .Attached directly to the top of the battery is the bmw rear power distribution box which contains the fusible links (non-replaceable) used to distribute power to the Junction Box and Engine Electronics, plus supply power to the Intelligent . Temp solution 2: wiggle the wires that lead to the battery power distribution box, take notice that trunk lights turn on and electronics work (connection is made) and car can start. It seems the problem is intermittent, but becoming more frequent.
Then you place the power distribution box on top of the battery. The power distribution box will be connected on a stud/post that comes out of the BST, which is visible on your picture of BST, with a separe nut though. That makes the positive electrical connection to the distribution box. I would like to know if the battery distribution box has a permanent 12v or only when i turn on the car? I want to know this because i want to get power for amplifier from it, and i want the amplifier to start ONLY when i have ignition on. 1) If you did NOT disconnect Negative Battery Terminal when changing pump, Fuse F07 (main power supply to pump, UN-switched Battery Power) may be blown.

There's power in the battery, but even when you try to jump the car, it's stone cold.
The symptoms you described are classic symptoms of voltage spikes in the vehicle power distribution system, most frequently caused by a failing voltage regulator/ alternator.
The errors are 2856, 286C. I have replaced all of the main parts given a lot of them were leaking any way (car is old). So i replaced the: cam shaft sensors, vanos, vvt servo motor and the eccentric shaft sensor.

Try twisting the battery cables where they connect to the battery. I've had corrosion develop and while everything looked normal nothing worked. Once I twisted the cables on the battery terminal I broke the corrosion and everything worked fine. The FIRST steps are to test battery, test for Resistance between Battery terminals for parasitic draw, inspect Transfer Points & Battery Well, and identify the three B+ Cables, their Function, and HOW to test each. "Over time, the positive battery cable connection at the front power distribution box loses connection." Symptoms include vehicle failing to start, central locking system failure and key doesn't insert into key slot.
