N75j on my standard car

[Ardz83]

Hi guys
I have heard that a N75J valve may help my performance abit. Will this work on my standard 1.8t 1998 A4?? Or will it just screw with my ecu and go into limp mode?

Thanks in advance
Dan

You can save a fortune by nodding the existing N75. Simply remove the valve and turn the screw in the recess 1/4 to 1/2 turn anti-clockwise. Screw is ******* tough to turn though so make sure the screwdriver is a good fit.

I just unplugged it and the car runs so much smoother it's unreal. Is that right??

 

[aragorn]

um no.

With it unplugged you'll only get 4psi of boost.

 

[Ardz83]

That's all I was getting anyway. Wrong?

 

[Oranoco]

You should be getting 7psi on a standard car.

 

[Ardz83]

No I'm not seeing that. 4-5 psi is all I'm getting. Should I try a new n75?

 

[aragorn]

are there any fault codes?

Perhaps you've got a boost leak?

 

[Ardz83]

I'm bidding on a vagcom as we speak. O do have a forge split r valve of that makes a difference?

A common problem with the N75 is the wiring that goes to it. It can break internally. It seems not quite long enough to me. This was my problem anyway and I've heard of it happening to others too. Good luck with it

Yeh that happened to the old A4 of ours.
