Replacing vacuum lines - 530d

Recommended Posts

Hey,

 

Does anyone have a 'how-to' for this task.

I know it's not rocket science but a bit of advice would be good, and maybe a diagram?

 

Also, whats the internal diameter of the hose I need?

 

Thanks.

3.5mm internal, 7.5 external. No real how to guide, inlet manifold off is the best bet and replace one at a time.

More importantly where are you getting the Vac lines from?

 

I wanted to change for silicone but couldn’t find the correct size.

 

Think you need about 5 meters on the 535d. Maybe less on the 530d as it has less actuators. Maybe?

530d has a lot less vacuum hoses compared to 535d, which has both turbos and boost valves vacuum operated.

 

530d engines with DPF have electric servo on turbo so there is no vacuum control on turbo like previous M57 or M57N without DPF.

Vacuum distribution piece under intake manifold. From there vacuum hoses to three solenoids (all found under intake manifold). From solenoids respecting vacuum hoses to 1) intake manifold swirl flaps 2) EGR valve 3) engine supports

Have you identified a supplier of quality replacement hose yet?

I got this cheap and cheerful hose https://www.ebay.co.uk/itm/200948869836

But I managed to bag a bargain 20 meter roll of Pierburg 4.07371.04.0 for£28 as Amazon must have wanted it gone as the price dropped daily from £90 until I bit, it is a high quality cohline 2122 in the box and doesn't come cheap per meter. I only did my turbo lines with the Topran one so I'm going to redo them all with the better stuff.

Yeah i would have thought any hose with the right internal diameter would do the job...

 

even the pink silicone stuff!

Accept try finding the silicone stuff in the right diameter...even pink!

I've not yet got around to this, been dealing with a split IC pipe and an oil leak...

Whilst looking for the leak, I peeked under the inlet manifold and could see a vacuum connector with hoses attached.

The nipple on the far left has no hose attached - what should be connected here?

Nothing, your car has a blanking cap fitted, could be due to an electric turbo actuator?

Exactly. That one would go to EU3 (no DPF) with vacuum actuated turbo.
