BMW X6 E71 PCV Valve Location

[Mr Mac]

New to here and for the like of me, YouTube and doing Google searches I seem to find many different models that all vary in where to find the PCV valves.

I just cant seem to find where the PCV valves are located on my X6 E71 40D.

Recently replaced the glow plugs but the level of smoke out the exhaust since is quite noticeable whereas prior to replacing the glow plugs it wasn't and doing my research all roads are saying the PVC valve will need replacing as it will have been split.

Any help would be appreciated and thanks in advance. Guy
