(it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle âÂÂdischarged batteryâ complaints.
Discharged Battery Energy Diagnosis Must Be Performed: The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle "discharged battery" complaints. In order to properly repair the vehicle the first time in the workshop, it is very important that the diagnostic test plans are performed to completion, with all results taken into consideration. Without performing the energy diagnosis test plan, the root cause of the discharged battery cannot be identified. This increases the chances of a repeat repair.
Power Reduction FC2A82 Intake VANOS and/or FC2 A87 Exhaust VANOS Camshaft Fault: The "Service Engine Soon" (MIL) lamp is illuminated and engine power reduction is perceived. This situation can occur after driving for some time with the engine at full operating temperature. If the ignition is cycled the engine then usually performs normally.
Various Electrical Problems Caused by Water Ingress. Water ingress into the luggage compartment may cause various electrical problems or faults associated with the MPM (Micro Power Module); PDC (Park Distance Control); M-ASK (Multi-Audio System Controller); CCC (Car Communication Computer); CID (Control Information Display); TCU (Telematics Control Unit); LOGIC-7 (Top Hi-Fi); RDC (Tire Pressure Monitor) or SDARS (Satellite Radio Receiver) control modules. In most cases, the water collects in the spare wheel recess. CAUSE: Insufficient sealing may allow water to enter the luggage compartment due to the vacuum generated while driving.
