I've purchased a new N75 valve and would like to DIY. Does anyone have a guide on how to change it or advise what needs to be removed?

It looks like the 'Y' inlet needs to be removed to get access - is this straight forward and would I need any consumable items/gaskets/O rings to refit?

Grateful for any advise.

Thanks,

Jim

 

Hi, i got advised to swap n75 valve or boost control valve, what caused you to think it is faulty?? Just curious. When i browsed the net i could only find details on vw/audi forums

 

The Queen said everyone has to swap theirs....j/k

I remember reading in one of the posts that not being able to hold boost or spikes could be caused by it IIRC.

 

3 lines go on it... its easier to take out the Y pipe... thats it...

 

Sorry cannot help you but can I ask a question? Do you know the location of this valve or the Porsche part# so I can locate it. I did a search for it in the repair and parts manuals and got no return. Thanks, J.P.

May be on this parts cat page item# 44 (cycle valve)

 

What are the symptoms of failure? Is it common?

 

Symptoms, location and P/N within this thread:

it's not as easy to get to as it appears in this picture though.

Cheers,

Thanks Mark that's great..
