2000 BMW 3 SERIES Structure Problems

I HAVE A 2000 BMW 323 CI CONVERTIBLE AND HAVE PROBLEMS WITH THE REMOTE TRUNK RELEASE. NEITHER THE KEY FOB NOR THE RELEASE BUTTON FUNCTION; THE ONLY WAY TO GET INTO THE TRUNK IS WITH THE KEY IN THE LOCK. I DID SOME ONLINE RESEARCH LEARNED TWO THINGS. 1. THIS IS A VERY COMMON PROBLEM. (TYPE 'BMW TRUNK RELEASE PROBLEM' INTO A SEARCH ENGINE TO SEE THE EXTENT.) WHILE THE PROBLEMS I HAVE ARE MERELY ANNOYING, IT IS NOT HARD TO IMAGINE THEM BEING FAR WORSE. 2. THE PROBLEM IS IN THE HARNESS WHERE THE WIRING GOES FROM THE BODY TO THE TRUNK LID. THIS LINK IS CONTAINS SEVERAL PICTURES OF EXACTLY WHAT I FOUND WHEN I PULLED MY HARNESS BACK: HTTP://WWW.M3FORUM.NET/M3FORUM/SHOWTHREAD.PHP?T=248956. IN MY CASE, THERE ARE THREE COMPLETELY BROKEN WIRES, ONE THAT IS HANGING ON BY A FEW STRANDS, AND ABOUT 4 MORE WHERE THE INSULATION IS AT LEAST...

THE REAR DIFFERENTIAL IS COMPLETELY TORN AWAY FROM THE SUB-FRAME CAUSED EITHER BY WEAK SHEET METAL USED OR POOR DESIGN. AS A RESULT COUNTLESS OTHER BMW E46 OWNERS HAVE EXPERIENCED THE SAME. SHOULD THIS ACTUALLY TEAR COMPLETELY OFF THE VEHICLE, IT HAS THE POTENTIAL TO CAUSE A MAJOR ACCIDENT AND A POSSIBLE FATALITY. PLEASE SEE THE PICTURE OF MY VEHICLE AT HTTP://JAYHOWELL.SERVEBEER.COM/IMAGES/BMW/SUBFRAME/SUBFRAMEDAMAGE.JPG. *JB

VEHICLE STARTED MAKING STRANGE NOISES FROM THE REAR SUSPENSION WHILE DRIVING. TOOK IT TO A MECHANIC WHO CONFIRMED THIS WAS THE SUBFRAME OF THE CAR TEARING AWAY FROM THE UNIBODY. HE ALSO STATED THAT THIS IS A FREQUENT OCCURRENCE IN THE E46 AND E36 BMW MODEL VEHICLES AND HAS SEEN IT BEFORE. WENT ONLINE TO SEVERAL RESOURCES AND CONFIRMED THERE ARE MANY OWNERS WHO EXPERIENCED THE SAME PROBLEM WITH THEIR SUBFRAME TEARING, CRACKING, OR COMPLETE TORN AWAY. *JB
