My BMW journey has begun

You need one of these in your toolbox. $3.99 at Walmart.

Thanks, I will definitely keep this in mind when I get to sunroof repairs. Speaking of sunroof repairs I could not find any information on how to repair a slow sunroof. It currently needs assistance to close. Is it true that they are the same as Porsche?
 
Does anyone have a source for these wedges? Not that I doubted you but it was like glue in there. The rollers are soaking in acetone in my ultrasonic cleaner

I'm going to 3d print these out IGUS (low friction brg material)
Is yours electric? It uses the famous sardine can motor like earlier coupe window motors under the zipper in the headliner.
Yes, Its electric

that is a door latch. there are 2 plastic grommets that go into the 2 slots (upper left and to the far right) for the lock rods - you need 4 of them. part #
those are available from BMW - i bought some over the winter. the best thing to do with the door latch is to clean it up real good and lubricate it. if you want to make it look great, you can re-zinc it.
 
You need three for each door, eliminates the rattles. You’re going deep which is good! My key wouldn’t lock the door until I soaked them in gasoline.

If you re-zinc it, do you have to disassemble it? Or can you do the entire assembly as-is?
 
that's a good question Scott. i do not know as i didn't do mine yet. for now, they are back on the car but i figure that i need to do something about it. i wouldn't want to try to dismantle it ... kinda complex. paging @TomHom ... seems like you have had some of these for sale in a refinished condition. care to share a little knowledge with us?
 
you can plate them assembled. Typically best to remove the springs first as they can be harmed by the process. That being said I have left them before and it wasn't an issue. They do look great after plating. More satisfying building it back up when everything is fresh.

Yeah I was thinking the plating is very thin, so prob ok to plate them as an assembly. Trick is cleaning them. Prob ok to vapor hone them, although they will have a somewhat matte finish
 
I ran them through my ultrasonic cleaner with acetone for 24 hours. Then I put it in a Ziplock bag filled with ZEP (lubricant) and blasted them again in the ultrasonic cleaner. Even after all that the lock mechanism wont work. Thanks for the link for the

The electroplating process will introduce hydrogen embrittlement on high hardness parts like springs. Baking them immediately after plating can greatly reduce the risk.
 
If it isn’t rust that you are going to cut out, i have generally wire brushed down the area to remove any loose stuff and then painted with Rust Bullet, which is a paint with anti-rust properties. I believe others use POR-15 which is a similar compound. Obviously these aren’t restoring any strength to the area but are anti-oxidizing and should prevent further rust from spreading as long as you’ve taken care of whatever led to it starting in the first place
