2.7t BES 2005 vacuum lines schematics

[powerarmor]

Can anyone support me with BES 2.7t 2005 vacuum lines schematics?

I am going to visit my friend who has a smoke tester to check the vacuum lines. With the schematics checking everything would be much easier.

Thank you! Much appreciated. Man, but this first schematic is huge. I don't think I will manage all those parts

@ first I would like to look at:
1. N75
2. N8
3. non-returning valves
4. Vacuum reservoir (???)
5. Mechanical air-recirculation valves
6. N80
7. Pressure limiting valve

I've already learned that when mechanical-air recirculation valves are damaged, they have a vacuum leak, so it should be simple. And all non-returning valves- you just need to do the "blow" air test. What about others? Do you know how to check them?

I've marked the components to be checked form the 1st diagram, is there sth more?

Idle is sometimes very rough and car is jerking terribly when accelerating on low rpm. On high revs it runs quite ok, but there are occasional 1 second power cut-offs durng kick downs...
When weather is cold car is running better. And I need to change both o2 sensors every 5000 km, cause they get damaged... After replacement car runs perfectly for a short time.
All the time I get bank 1 and 2 system too lean errors.

No Longer Available. You could always run a flexible silicone line in its place.

My hard plastic line broke so I put a ID 5mm silicone hose over it and clamped it to either side. Works great and cost me $0.50.
