Lets talk about Breathers...
Whilst waiting for my car to go in next week for the DPF to be re-instated I thought I would do air filter and crankcase breather. I purchased one off Ebay that looks identical to the current one on the car(genuine BMW) however it came with a little cartridge. What does it do?
In the end I fitted exactly what was removed as couldn't see what this cartridge would achieve. |

I think the general consensus was this was to aid the swirl flap mechanics. |
