Howdy M57 Family,


I am working to diagnose a boost leak on my 2010 335d (180k). I went ahead and removed the intake/air filter housing and removed the boost charge pipe (AA Rodreguez upgraded part) and removed my intercooler to check for signs of a leak from there.


Everything looked decent besides the exterior of the charge pipe being covered in soot/oil. Intercooler had an oil residue inside it, but no standing oil whatsoever. After getting that all removed I start to take a closer look at the turbo connection pipes themselves and noticed something very strange.


The connection pipe that runs from the upper turbo to the charge pipe connection is missing 2/3 brackets and bolts that are supposed to hold it in place (I think..).


the attached picture you can see that the left connection pipe has 2/2 bolts and brackets, while the right connection pipe running to the charge pipe connection only has 1/3 bolts/brackets.


I am going to take a wild guess and say that this could be a major boost leak as I can wiggle that right side connection pipe just slightly by hand, while the other doesnt even budge no matter how hard I yank on it.


I've ordered the brackets and bolts from FCP euro after looking up the part numbers on realoem.com.


Wondering if anyone else has ever seen this before, as I cant believe that they just fell out over time? Any advice or help is always appreciated.

Thanks!

They're not missing, that's the way it comes from the factory.

you are missing 1 bolt and keeper from the bottom section .....the LOWER hole in the bottom section.
