None of them - they're all either vacuum or atmospheric vent.

Neither of those will work. You need to tap into the charge piping somewhere, or use an "electric" boost gauge and tap into the MAP sensor wire. IIRC, those colors are as follows:
BLACK- Goes back to the airbox as a N75 vent line
GREEN- That is the vacuum source from the tandem pump so the N75 can pull on the actuator
RED- That line goes to the turbo actuator itself.
--edit-- damn, FUB beat me to it...

Listen to them ^ on the MK5 PD the upper IC pipe or near the intake manifold is easiest. A pic on the other side of the motor for you where my old stuff was tapped.
My gauge now is tapped directly into the Intake manifold at (middle right).

i need to rephrase this.
i tap into the plastic top intercooler pipe -> install my BoostValve -> then the tube leaving the Boostvalve must be attached to a hose such as my setup on my mk4 as seen below.
the mk5 setup does not follow the identical setup?

Ahh in that case for the boost valve T in to the green one.

see, if you had've mentioned a boostvalve in your original post...

Trying to get a little clarity on this exact topic. I have an '06 BRM TDI. Installed a NewSouth 0-30 boost gauge today. I've tapped the threaded fitting into the plastic charge pipe between intercooler and manifold. Question: do you have to splice a t-fitting to GREEN or can you just go direct from charge pipe to gauge with single hose?

Tube should go from where you tapped into the charge side right to your gauge. Little tip put a little bit of cotton from a qtip in the line to avoid gauge rattle from the boost. If it’s a mechanical gauge.

Yes, it’s mechanical. Going to disconnect the hose from gauge and make sure the gauge isn’t fubar using a hand pump. Just wanted to doublecheck and make sure hose routing was correct first. Thanks

The pic at the top of the thread are vacuum tubes and shouldn’t be used unless you only looking for vacuum. Diesels do not make vacuum naturally which is why they have pumps run by the cam. Most ASV delete kits have a hole tapped for a boost line. Maybe look into one of those unless you don’t want to delete anything.
Ps use a small amount of compressed air to move the gauge not a vac pump.

I already have an EGR and ASV delete. Didn’t get one with a pre-tapped pipe flange and should have looking back now

Can always take it off and tap it yourself easy and will be a better place to put it being aluminum.

If I hadn’t already tapped into the plastic charge pipe near the fuel lines I’d do that.

On a side note, I know for a fact my turbo actuator needs an adjustment. I have the infamous boost jump around 1800 rpm. It’s like nothing is happening then all of the sudden BOOM lots of boost

Probably sticky veins more than the actuator. They are electronic on brms.
Have you had the oil checked for cam wear?

Negative. I also know I have pretty bad cam wear. Trying to drive the car as little as possible. If I remember correctly, this was the #1

Oh boy you need to change that ASAP. I’ve done 2 and they aren’t bad.

Yea I know. #4 lobe ain’t great either. I plan on getting the Colt cam and a few other things before Thanksgiving (if I can last that long)

The second one I changed a few months back chewed thru the tops of the buckets....so there that.
