Yep crank case breather. Should be vortex type so no maintenance. They're a recurring topic on the forums as the early ones had a filter element instead of the vortex separator - these filter elements would block up, cause increased crank case pressure and then lead to premature failures of the turbo bearing oil seals.

Check it's vortex - and if so, can almost certainly be left alone.

Note - they are almost always a real pita to get to as they're right at the back so all the engine coverings and often some of the scuttle has to come out to gain access.

Thank you. It's wise to just replace the whole thing then?

Wise to check it, but - wouldn't replace for the hell of it. If it's vortex or empty it's basically a solid lump of plastic with gaskets - they can fail but so can every other piece of plastic with gaskets (eg pretty much every component on your cooling system: all the wiring harnesses etc).

If you're in there - have a look to check for signs of failure. If it looks ok, I'd leave it alone - they're quite expensive (about £70 iirc) so there's no point in turning them into a service item when frankly they just don't need to be.
