k03s n75 charge pipe

[OctavianC]

I have a problem. I have changed my turbo, the k03 with k03s(k03-052), after a lot of troubles I did manage to connect it to the engine. I did manage to connect all pipes except the charge pipe that is going to the n75 from the turbo.

On the old k03 the pipe was connected to the compressor housing. I am stuck for 2 days, because I have no idea where to connect it. I could improvise, but I need to know how it should be connected.

Thanks

Later edit: it is the 1.8t 150BHP, AEB

It's not clear what your issue is as you say you connected it but not the charge pipe.

Take a pic and post it up.

I did manage to connecte the coolant and the oil pipes. The problem is that there is the pipe that is going from the turbo to n75(a very small one). It was connected to the previous turbo, the k03 to the compressor housing. The problem is that I have no idea where to connect the pipe that is going to the n75 at the new k03s.

Sorry for not being clear, but I am a rookie with petrol cars, I did manage to replace the turbo so far on my own, this ios the only thing left to take care of

This may help.


N75 Valve Replacement BSK2005http://www.audiworld.com/tech/pics/eng70-n75_valve_location.jpg



30mins install time/difficulty 3 because of tightness

The N75 is located in between the airbox and engine just above the turbo in the hose going towards the airbox.
make sure your engine is cold when replacing or some burns will accompany this replacement!

Disconnect the plastic air filter connector from the air box and the front intake. remove 2 phillips screws and pull out the piece.

Remove the crankcase breather filter (pancake filter or what ever its called) to have better access to the N75.

Disconnect the cable by squeezing the silver security lock

Now comes the fun part to remove those twist on clamps. I used a small end banding snip plier and pulled up on the clamp side that has the notches. the clamp basically lets loose and can be taken off.

Remove all 3 clamps and pull the N75 out.

Replace with the replacement and put everything back together as it was and secure with clamps. I dont think that zipties would hold up in a high heat environment so do that own your own risk. I have the hoses on there without any clips so far.

Thats it!
058 906 283 F is the N75F valve
058 906 283 C is the N75C valve
Part number stays the same only the last letter changes to the actual letter designation

I went out for a test drive in the rain and I am spiking now at 18psi and run 16psi of boost with the giac chip. however the best part is that the boost comes on rather quickly now than before. I'm happy!

Thanks but unfortunatelly it doesn't.

In this pic I can see the n75 and the pipes, but I need to find where to connect the other end of the pipe that is in the middle (the second out of the 3 connectors) of the n75.

It need to go to the waste gate.
