Anyone know what this is loose in the engine bay? There are actually two of them both disconnected. They route up from underneath. It was raining so I didn't crawl down for a look. Looks possibly like they're part of some vacuum system.

Cheers Mike

They are definitely the breather pipes. In that position they are likely to be for the gearbox/transfer box. the other end will be connected to the boxes by a banjo bolt you will not be able to see.
There should also be one for each axle. which you will see the lower conection on the top of the axle, I cannot remember where the axle ones finish as I have extended mine.

They are not supposed to be connected to anything unless they have been extended for extreme deep water wading.
 
Thanks folks. Have googled and concur. I think they're meant to be clipped in somewhere rather than loose. I'll work it out. The reason I thought these were part of a vacuum unit is that I own an old Porsche 928 which has this kind of wierd stuff going on.
 
.....there is a plastic multi clip hiding at the back of the rocker cover on the EGR cooling pipe, which disappears towards the air box if the axle breathers have been unclipped
