Question about BMW 530
The problem is a short in your wiring harness or a bad ECM (Computer). As you have already replaced the ECM I would start tracing wiring harness for a short. Because the problem is so large effecting all the lights as it does and the problem occurs when you press the brake pedal it seems to be a short. Check the Fuse block and any wires leading to the brake pedal switch for bear spots that might be grounding or rubbing against another wire and check any splices you, or anyone else, may have made. Your looking for signs of a short between the systems. If by chance you haven't replaced the ECM after checking your wires and fuse blocks, there is most likely 1 in the engine compartment area as well as inside the vehicle, the ECM is the only other common area these systems interact. I hope this helps.
