- How to make sure you have connected you boost and vaccum hoses correctly on A VW T4 2.5TDi AJT engine. If you have the intercooler there is an additional hose that goes from the intercooler to the ECU
Thanks David, exactly what I needed for my AJT 2.5 van 👍
Cool, thanks alot!!!
Great info on T4. Thanks
Can you explain in detail the connection method of the blue hoses by recording a video?
Ok will try it out anf update
And I know I called the N18 the N75... DOH! but the connections are correct :)
Hi
I would like to ask you to draw a detailed diagram of the vacuum. Upil with ACV 75kw 2,5 aniekto from the shape picked all the vacuum. Thank you for your help.
I don't have a flap on the EGR.
The plastic T piece connector on mine has a narrow section that comes down the T. Is that correct ?
I think you mean the white plastic narrow pipe that comes from the plastic pipe, low on the front of the engine that runs to a braided hose going into the dash. if that's the case it controls the air re-circulation valve.
Hi what are the sizes of the inner(id) blue pipes for the n75 please
They’re a mix of 3mm, 4 and 5mm I got 3m of each and replaced them one at a time
lol. thanks for the vid. I have very little boost if any and the N75 error code came up so i think i may need to change the N75. Is there a away to test it do you know? thank you
Sorry just seen this. You can easily test it by removing it. Put a hose on the top one and then get battery. You can use a 9v. Blow into the hose and connect the battery to the terminals. That changes where the air comes out. If it doesn’t change or comes out of both the N75 is knackere
@DavidJohnston1970 hi. nose probs. it was faulty and 2 tubes on wrong way round. now it's just a slow as shit t4 and not a really slow as shit t4..haha
Can we see the boost gauge?
Can’t post pics as a reply, but it’s fitted where the triangle hazard warning lights switch is. Common place to fit them on a late T4. Loads of pics around if you Google it 😊
@@DavidJohnston1970 no prob. Any idea why gunk has appeared around the area where the hose/pipe connects at the turbo side?
Possibly coming from the hose leading to the crankcase breather valve? The o-rings go hard.
@@DavidJohnston1970 thanks I will take a look
