N75 has 3 fitted positions. Correct. Slow, and VERY bad.

Good way how to describe it lol.

I actually just went outside in the ******* rain just to quickly check to see if my N75 was on correctly as im experiencing the same as Dani. It was but easy to get it wrong if going from F - J as the ports are on the opposite sides.
 
Ok to clear it up, when it was running actuator pressure, i had the n75 so the long part went to the charge pipe and the short pipe to thr tip, now its short pipe to te charge Pipe and long pipe to the tip?
So is the n75 shagged or what? I cant see how it can be anything else.
 
Just looked at daves picture, ive got the bottom pipe going tothe actuator, is that correct?
 
Mine is connected correctly 100% and getting massive over boost and them 2 fault codes .........

HAve you tried a known working valve Nath?

Well my J valve was working fine, no fault codes or anything but the car felt flat (bum dyno, no codes to comfirm anything was wrong) so decided to change it to my F which as far as I can remember was also working correctly when I was running it before lol. But as soon as the F was put back on (fitted correctly) I was getting crazy boost and them codes straight. I also change my spring from yellow back to green but I doubt that would cause the crazy boost.

Just get yourself a brand new (Genuine VAG) N75 that's meant for your car and be done with it.

Thats the plan but going to put the J back on for now because it was boosting sensible values then.

Can you even get non genuine N75 valves.
 
Ye thats what im going to do I think, get one from Audi. The F Valve looks like the original one and bought the J from a ASN member.

Strange though because the F was working fine before I took it off. Maybe its been dropped etc while its been off.... who knows but haven't got a clue why its not working now lol.
 
No it wasnt welly, the bottom has been to the actuator both times around.

So to clarify, long pipe to tip, bottom pipe to charge pipe and small pipe to actuator?

How many times!

Bottom pipe to the charge pipe, front to the TIP, rear to the actuator ;)

I'll try and find a pic of mine.

EDIT, These any good?

Stop getting ya knickers in a twist westle haha. Right as soon as works done, going to correctly install the n75 and see what the drive home is like haha.
 
Ok, westle, in the most none gayest way, i love you man haha.

So it turns out theres 3 ways to fit a n75 haha.
1. The totaly wrong way were the car runs actuator pressure and thats it.
2. The run boost's but spikes like hell, constantly hits limp mode and runs like a bag of crap on part throttle.
3. The right way, haha.

Cars driving amazingly, the best ive ever known it, boosts to 11/12, rising to roughly 14psi then holding to about 11 psi to redline, all in all a very happy dani :).

Thanks for all the help lads.
 
:thumbsup: Good job Dan, them boost levels sounds bang on.

You can finally start enjoying your car again :)
 
Yeah, honestly i cant believe it.

I think i can officaly take the title of audi-sport's very own special child, lmao.
 
Im glad its sorted,
But i hate to bring it up Dan... The first time i met you you had no boost because... you hadnt plugged your N75 back on.
These things can get very expensive,
