The new cyclone separator is part of the crankcase depression limiter and is BMW part no. 11 127 799 367 (for BMW M47 engine). It comes with new gaskets. They cost ~£18 + from BMW dealers. They do not need replacing, perhaps just an occasional paraffin wash.
It is located on the cylinder head behind nos three and four injectors. To gain access remove the plastic engine cover and unplug the injector electrical connections. It is retained by four Torqx head screws. Easy to replace, just dont bother with the L/R "filter" type again.
This question arises so frequently, doesn't it warrant being made a Sticky?

Thanks to this site and some pictures that were put up on this. I changed mine, just for a the filter for now. The difference was amazing. The car is now so smooth. I had oil coming out of the Oil cap not the dip stick. I did not not about this when I viewed the car. I asked the owner what the oil was doing all around the cap and he told me it was where he had spilt a bit of oil whilst topping the engine. I now this to have been a bloody lie! Seemed a bit clueless on the car TBH and I now wonder if they were getting rid of the car due to being a bit scared by this.

Hi, I went to my local BMW dealership today and purchased the above part number (£19.46 + raggy matt)
Is this all I need to replace the old LR set up as I also have a part No for a separate filter unit and for a whole assembly.....
The part I have is a plastic piece that splits into 3 pieces. It also includes 2 rubber seals and an O-ring

You only need the cyclone bit, part no. .....367, which separates the oil fron the gases going to the inlet manifold and returns it to the sump. The unit also contains the depression limiting valve which, if it is working correctly you do not need to replace.
The O ring seals the cylone to the unit while the other rubbers are replacement gaskets to seal it to the cylinder head.

Well, fitted the part yesterday.....absolute doddle to fit but you have to take quite a bit off to get to it, still only took just under an hour to do
Car feels much better, seems to idle more freely (sounds less like a transit) and will now easily rev past 3k...would struggle before hand!
Well worth 23 quid and an hour of my time
Annuvva convert!!
Surprisin' what a big effect a little bit of bunged up fluff can have on the performance of such a complicated lump of metal.
Do you think it could have been designed in at the request of the dealers to get business from worried owners and run up exorbitant bills for swapping out parts at our expense?
When the word really gets out they'll all be doin' it.
Chalk one more up to the zone.

Hi,
Last week I spoke to a BMW driver about the cranckcase breather. The part is apperently not maintenance free. At about 80.000km/ 50.000miles it should be cleaned. But, that is a lot better than the original.

I'm not sure about BMW, but a local independent I know says they are supposed to be changed at around 30 or 40k as part of their servicing.
Now, Land Rover also originally stated the same thing, and then later when this problem became evident, updated their service menu to include an element change at every main service - so that's one every 12 months at least.
Now, if you use a non Land Rover savvy garage, it won't have been changed. In fact I know of at least 2 local garages who like to play with Land Rovers who do not change this element at service time. One even told the customer they needed a new engine when the oil ebola started.

My TD4 had a service at the main LR dealer 1000 miles before I bought it. When I removed the crankcase filter, a couple of days after purchase and after fitting the EGR bypass, it was obvious from the condition of the filter element that it hadn't been changed for some considerable time so, in my opinion, trusting the main dealer is not always advisable.
