One problem related to tail light switch has been reported for the 2004 BMW M3. The most recently reported issues are listed below.
The rear lamps in my body panel that house the brake lamp, turn signal, and tail lamp stopped working and needed to be fully replaced. My car is a low mileage vehicle. This same issue was the subject of NHTSA #11v438000. However, this recall did not include the M3, just all of the other 3 series Bmws. Please investigate. This is a safety issue and a costly repair for me. This is the reference found on your website and my issues are identical to this summary: NHTSA campaign number: 11v438000 rear lamps in body panel summary: BMW is recalling certain model year 2002-2005 325i, 325xi, 330i, and 330xi vehicles manufactured from September 1, 2001, through March 1, 2005. Over time, resistance in the electrical contacts may cause one or more rear lamp functions (tail light, brake light, and/or turn-signal), within the vehicle's body panel, to stop working. Thank you for looking into this.
