How to fix wastegate rattle

Catalina Wine Mixer · 04-14-2012, 10:08 PM

my buddys 335i's wastegate rattles on start up and sounds like a damn lawnmower is there any solution besides replacing the turbo. His warranty is up fyi.

thanks

Does he have a tune of some sort?

LOL... search...

A couple options:
1) Replace wastegates (and turbo assembly)
2) Adjust wastegate actuators (you can really only adjust the front one) - search Mr5's fix
3) PROcede has wastegate fix that works on some cars
4) I've heard JB4 improves wastegate rattle, and Cobb improved my wastegate rattle

Option 1 will fix wastegate rattle temporarily if at all, but it will come back.
Option 2 only works for some people and only for the front wastegate
Option 3 and 4 only work for some people, but the rattle is still there.

Learn to live with it.

I actually hope my rattle means this...my warranty company already approved new turbos if needed lol!

nikitino25 · 04-16-2012, 07:15 PM

So the rattle isn't causing any harm or anything?

No. You need new wastegates, but BMW gives you new wastegates by giving you new turbos.

I had the rattle, they replaced turbos under warranty and rattle came back. I've installed a procede v5, and adjust the opening and still rattle a bit on cold for about a minute and goes away. I have it set to 85%.
