I have a 2003 M3 that is starting to have noice while opening the passenger side window. I kind of clunks. How do I fix this ,can I fix this myself or is this best left to the dealer.
You will likely need a new window regulator soon, so don't open it again unnecessarily, because it will invariably break when open and then you won't be able to get the window back up. And then it will rain. Hard. Anyhow, find a good independent BMW shop and have them fix it. I don't know your level of skill or what kind of tools you have, so I could not tell you if you are able to fix it.
