Hey all. Just wondering if someone could help me out. I have an 05 mz3 SEDAN and have this extremely annoying creeking coming from somewhere around my back seat. It happens when its is cold outside, and whether i have the seat up or down. After i got home from work today, i put 1/2 thick foam tape (insulation tape that goeas around your doors in your house) between the three plasic interior panels that meet together behind the rear seat. I had a creek coming from my center console, and did this a while back, and viola! fixed! But no luck with the back seat!! Has anyone else had this problem. Any knowledge of where exactly this sound might be coming from, and any possible solutions??? Ive looked around on here and havent found anything yet. Any help is appreciated!
