The item listed as item 24 on this drawing is a wear stop. It appears to prevent two metal pieces from contacting each other when the top is closed. There are two of these on the end of the first joint (one on each side) in the mechanism when you fold your top. There are two more behind the linkage connected to the first crossbow and not shown on this drwaing. I have spoke with a couple of people who said they had these replaced under warranty. For those of us past the warranty they are $12.50 each piece. Four are required. This is a 1/2 inch by 1/4 inch "U" shaped piece of plastic for $50.00 a set. BMW's pricing defense is they sell so few. This is a part that is designed to wear out to protect another. I found mine missing by accident. I'm quessing there are a lot of cars with this piece broken or missing and the owners are not even aware. Please take a moment to check and see if your are missing and broken. Maybe if the demand becomes higher we can get the price down. If not maybe at lease some of you can discover the problem while BMW is paying the bill.
