E92 325d crankcase breather

Hi everyone, I could do with some help. I want to change my crankcase breather on my m57 e92, it's a 57 plate. I have read there is two different types and I've no idea what type will be on my car. Which type is best? Etc

Go for the vortex style, the loo roll type are known to clog up very quickly. I fitted a loo role style to my 330d when i purchased the car and within 20k miles it was clogged up, now swapped it out for the vortex style.

The breathers mentioned here were for Diesel's only. the Breathers in the petrol variants are different. not sure on the 320i but i had a 325i e90 for a while which i got the breather swapped out on and its alot more involved cost wise and labour wise. Unless your having issues, on a petrol car, i would not bother.

Hi,
First post here.
Found this excellent step by step AFTER I had replaced the air filter on my e92 330d. Had an e46 320d and learned the hard way that this really is a lengthy knuckle scraping process. Totally agree with others that BMW have made this a needlessly complicated task. Why is access to the filter so poorly thought through.

Rant over...
Whilst I had the covers off I thought I’d also inspect the crank case / turbo breather to establish if it had a filter which may need changing or cleaning.

My previous e46 320d had a small round filter which was totally clogged. Replaced this with the maintenance free vortex upgrade for peace of mind.

The crank case breather on my e92 330d appears to also be the vortex type.

I just gave the inside a wipe and re fitted

Anybody got any thoughts or info on these breathers? Are they pretty much maintenance free.
Please note I will not be chuffed to learn I’ve missed something!

Only those who have changed one of these air filters will understand
Cheers for any comments
Rob
