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)

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?

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..
