Update : Fitted 710N valve & N75J valve!!!Good man great company and a excellent product. Don't know any other place that sells them. Even hard to find used ones. Buy it before their gone. Works like a charm, came packaged nicely and sealed. I installed the N75j in my 04 jetta and it works great I really enjoy the effects it has on my car. These are nearly impossible to find, It will add some nice performance to the k turbo in my 04 Passat. Boost Valve - N75J - J. AUDI 2. No this is not a typo No these are not manufactured in China No these are not "black" N75 valves Yes your eyes are working. These are a known upgrade for the 1. For years "tooooners" have fooled the mass community into believing this was some special trick valve but rest assured they were simply using an OEM part number. Thank fully being the Audi nut I amI managed to procure these. The part is listed as NLA No Longer available from Audi so its basically whatever we have in inventory that is available. Not sure how clearer that needs to be. Before shipping we ensure the valve is working by testing it. I wouldn't waste my time or yours shipping you a dud valve. If you get the valveinstall it and notice "surging" then you installed the vacuum lines wrong yes you need to redo them in the opposite way. Think about what the N75 valve is for and then think why you would have surging issues after installing it its keeping the gate shut! If you have questions simply ask but if you purchase this like the know it all from WA or the impatient child from MA and then file a claim without even contacting me ,you will be ignored and be forced to deal with ebay. We have sold over of these both on ebay and through our other online retailers. They workhave worked and will continue to work. Don't like the above then simply don't buy it from us. Leaving negative feedback because you can't install the valve or simply can't wait 5 days for your product to arrive is a juvenile thing to do. Purchase this part elsewhere as your Ebay purchase will be cancelled. Thank You Just got my plug wires in today. Installed them on my car. Very pleased with the. Lovely Don't know any other place that sells them.

Think i need a new N75 and was looking at a "J" version,however i am also looking at a stage 1 re map Anybody give me a confirmation one way or other. Joined: Nov 15, Messages: Likes Received: 0. Your better off getting a stsndard one and putting the rest of the money towards a remap, whats happening with uour old n75 valve? Yeah pretty sure it's the N75,all the symptoms are right. Im just waiting on a price for a Remap,if it's reasonable i'll probs get it,but just a Stage 1. I should stop reading all these posts,just confuses the hell out of you,was quite impressed with the alleged 2psi increase on the "J" valve,but did say not as good on remapped cars,so want to be sure as i need valve now. Anyone have a "J" valve fitted? The one on mine is the e version. Joined: Jul 24, Messages: 5, Likes Received: 4. Id stick to replacing like for like. Not had an N75 fail but from what Ive read on here they usually let boost build then stop then build again. What you have sounds more like a general limp mode which could be lots of things. Have you checked for boost leaks? Id deffo try a new n75 valve, whats probably happening is the car is running fine,no boost leaks,its just the n75 isnt letting enough boost through,thats why its not throwing up engine codes, when i first bought my cupra it was only boosting to 8psi,no codes,no boost leaks,the valve had probably seized in one place, sonn as i put a new one on, i had full boost.

Im getting the same problem, sometimes it pulls like a train right up through the gears but sometimes you hit I know its supposed to drop off a bit but mine seems to drop substancially. I thought it might be the dump valve so I stuck on a forgethat didnt fix it makes a nice noise now though. I think I'll try a new N75 now as I dont think its a boost leak surely it would have no boost all the time if that was the casebut I too am confused to hell by the different types and their merits and drawbacks. Think Ill probably just do a straight swap f-type I think its cheaper than the others too. Joined: Apr 23, Messages: Likes Received: 3.
N75 Valve Tuning Investigation
Lots of Fun. N75 Valve part number and availability. I've searched and searched and cannot find a post that lists the part number for an N75 valve. I've gotten code P, and read alot about my what I'm experiencing currently. Low Power! I want to try the N75 Valve first to see if that fixes it. Also, where can I get one from locally? Besides the dealership! Their markup is probably crazy! Also, I read somewhere that the valve is supposed to click all of the time. Mine doesn't, is this a problem? I think I just found it: 1JA? No greasecars, please. Click on username for E mail address. PMs are turned off!!! Holy crap. I work in Hunt Valley, I'm headed over there in a few minutes after I finish my sandwich. Thank you very much! I ended up not having to get a N75 valve. Before I even started my trip I decided to check everything under the hood. I found a vacuum line that was loose. I put it back on and everything is good right now. We'll see on my way home when I'm merging into traffic if it rears it's ugly head again. Hopefully that is all the problem was and nothing else. I drove it around for about an hour and nothing, but I didn't really get to push it much during that drive. If you ever need to check it again swap it with the EGR solenoid beside the N75 and see if it improves the situation. Troubleshooting Low Power Having trouble searching? TDI s : T4 2. Find More Posts by test pilok. I've a T4 ACV 2. Turbo is delivering more than is being requested. My tech acquaitance doesn't think the MAF is the issue. I'm off to further search on here, but should there be a link to this process I'd be very greatful-this site is HUGE!! Thank you enormously. Thank you kindly CG. This place is a seriously major repository of info. Pat yourselves on the back!!
During the course of the S4 community tune efforts a couple other cars that tried using the tune I am helping to develop experienced over-boost on the initial ramp up. The immediate action was to lower DIMX on their tunes to try and bring the boost curve closer to what I was experiencing. This left unresolved the question of why we were seeing different boost profiles when using the same tune. As in the case of the S4 community tune the APR tune had been built on my car, and other cars would occasionally see boost overshoot on the initial boost ramp up. This was determined to be a logical cause for the over-boost seen with the other cars. After contacting the owners of the other cars involved with the S4 community tune we took photographs of our respective N75 valves and compared the setting. While this investigation is presently incomplete, it appears to be a good lead into the cause for the disparate boost ramp-up curves between my car and the other two. I dug up a spare N75 valve that I have and worked on changing the setting to try and increase the rate at which the boost ramps up. I vaguely recall that the adjustment screw may be fixed in place with loctite, because getting it to budge took some effort. After installing the N75 valve with the updated setting I took a drive and logged the boost onset. My car is now over boosting initially, unlike prior to adjusting the N75 valve. This is a great result because it will enable me to make tune changes that will hopefully produce similar outcomes amongst the three cars involved with the tuning project.
