Bmw e60 pre lci vacuum pipes

[Pvapour]

Have replaced all the vac pipes under the inlet manifold but cant see any over the turbo side, is there any?

Searching has turned up a diagram showing a vac bottle on the 535d and also the e39 530d but nothing definitive for the 530d.

I removed the airbox but the plastic base plate of the box section looks like its part of the main inlet manifold and doesnt seperate, am i wrong?. Is there anything under there anyway?

Any help appreciated (Have posted on bmw forums to)

looking like there is http://www.realoem.com/bmw/enUS/showparts?id=NC71-...

Looks like that is showing vac pipes just for the turbo, which I think most e60's, even early ones were electrically actuated instead, so I don't think there is.
It should be easy to tell tho, all the vac pipes on those engines are fed of the one pipe under the inlet manifold

Thanks, that main vac line has a 4 branch 't' piece and one of them is blanked off as surplus to requirements, guessing thats because of the changed to electric actuated turbo.

Cheers, saved me looking any further for boost loss solution, have checked all the intercooler pipes and thyre fine.

Allot of carbon build up around exhaust manifold area in engine bay + strong smell of fumes, could a cracked manifold cause the loss of boost?

It's quite common for the early e60 diesels to crack the exhaust manifold and leak a bit, normally u will see soot and smell it, but don't normally affect boost, unless it's really bad I guess.

So u have no boost at all? Or intermittent loss?

[Elliot2000]

I just see ur other thread, so do u think ur dpf is blocked again, would make sense for what u are saying. It's not overly common for them to block up for no reason, so it could be egr sticking open or defective actuator causing it

Its a loss consistant but higher up the rev range, getting worse as car gets hotter, (maybe crack opening up more as car warms?)

Not only is the allot of soot there but this crack has been there for some time as car has always smelt fumy from outside, never gave it a thought tbh and had no time to do anything, but the car has never really revved out as it should but i dont drive like that much anymore so was never a bother.

Now when i put my hand down the side i can feel a significant blow on my hand, so it needs to be done anyway wether or not its the cause tbh, its all stripped down and manifold on way.

I think the dpf is ok as the pressure values before and after the dpf seem within tolerances ie the differential is not that great so think we're ok on that score

One other thing i have is a maf code 3ff0 which results in a limp mode in addition to the booost loss, unplugging maf and running negates limp mode though so have ordered one of them to, damn sight cheaper than they used to be!

Thinking maybe its a good isea to get turbo rebuilt while its off, there isnt significant play but enough to be producing a slight whine..

[Elliot2000]

3ff0 is never usually the maf to blame, it's basically saying the measured amount by of air taken in by the engine is too low compare to what is calculated it should be, normally cause by a restriction or an issue with egr. Iirc on them engines it was normally coked up behind the valves and in the inlet manifold which was the most likely cause. But I guess if u also have a boost problem it may cause that fault too, but usually in conjunction. With a boost pressure fault
