Rusty Nut on DCT - BMW Metal Quality
Today while working under my car (with the tanny cover removed) I found this rusty nut:
[/URL] Looks like its on the shifter linkage to the DCT. How can it be that it's so rusty and flaking already? Car is a 2011 with 14k miles. All the other nuts and bolts look good except for this one. Wonder if they had a defective batch... |

That nut holds on the emergency park release lever. Moisture and salt will rust any form of mild steel, even stainless over time. It's just surface rust, nothing to worry about. You can see the corrosion starting on the trans as well in that picture.

I noticed all the corrosion on the aluminum as well. Must be from the salty air at my office since it's near the ocean and right on the intracoastal.

On my '01 A4, trim pieces started to rot after about 5 yrs. Then the welds on the exhaust system rusted out about a year later. For whatever reason poorer quality steel is used in some locations. I guessing that the engineers over-look things like this. That nut on the DCT looks overly rusted given the time frame. Give it a few more years and a wrench might not grip it. Then again the image is a little out of focus and the rust might just be a thin skin.

No. This caught me by surprise but I'm planning on looking into getting a new nut on there before this one seizes in place. Just checked Realoem and this nut relates to the linkage from the DCT shifter. I was unable to locate the nut as a separate part, which is not good.
