n75

Hello I have a question about N75 valve. I noticed that some of us change it to a different one. Are there any REAL advantages coming from that ? Ive read that it helps to kep a higher boost but ... im not sure if that will be healthy for my engine if it was remapped to use some specific...

im getting 17956- n75 open circuit - intermittent now after having a search people generally say to replace the n75, now this seems to have started since i had all these problems with boost hoses flying off, i cleared the code last friday, checked it tonight and its back. thing is, could...

NO doubt the title will be edited to suit, but ive got a problem with the LCR boosting, its running an n75 and a manual boost controller, ive removed the boost controller, car still has boost problems, boosting all over the place and dropping off, wont hold boost properly at all :confused: I...

I noticed my car was down on boost the other day (18 psi instead of the usual 22psi) so just had a look under the bonnet. Where the charge pipe has the small hose that goes to the n75 valve had popped off so i put it back on and the car wouldnt boost at all! So i blanked it off and now it hits...

when i come out to start my car in the morning and maybe during the day my car seems to lack power ie as if there is no turbo then when i pull over and start the engine again its fine it has been mapped and there is a 17705 code being thrown up can someone point me in the right direction many...

As title......I no a few people have changed these but why? And whats the difference between them. Bobby

Heres two pics: Is my car still driveable? How can i fix it? I was pushing on my induction kit as it was a tight fit and the part you see in the pic snapped! I really don't know what to do... paniced a bit lol Any help would be very much appreciated! Thanks, Ross

Hey, After the fun and games in the snow the last few days I was wondering if the following would cause any problems?? Could a switch be put inline with the N75 to enable it to be switched inside the car. Reason for asking was that I forgot to reconnect it after I fitted my 007P and it...

Just got me a new N75 J (034906283J) but i noticed the in/out plastic legs are different lengths if I keep the electrical connector facing the same way.. I.e the metal case is inverted. Are these fitted in the same orientation as the Standard "F" valve. or am I keeping the pipe lengths...

The main problem I have is hesitation when changing gears and leaving from a stand still. As soon as I let go of the clutch the rpms drops and get a hiccup then it revs almost as it should. The same happens when I'm changing gear. MAF, O2 sensors have been replaced but the problems still...

can you bypass the N75, I had my car remapped and he said you can bypass it as mines playin up but I cant find any links or threads?

maf problems hey not on this often but am having trouble with my cupra and hoping somebody here can help me. my car when accelerating would sorta jump through the revs changin from full power to no power going throught the rev range. i seen on here that it could be the maf and got a new one...

Hi guys did all my n249 bypass and n112 today easy than what i thought it would be! but still my car is boosting to 12 psi for all of 1 sec then drooping to 8psi and it never did this until a month ago. it is not the maf and i cant find any boost leaks. but if i unplug maf it boosts to 12psi...

Hi has anyone messed with different N75's on Cupra R's? If so whats best or should they be left alone Cheers!

I'm thinking of upgradeing my N75 valve and would like to know what one you lot would reccomend, 'J' or 'race'. My cupra only had a stage1 p-torque map and will have a green pannel filter by then. So will it cause any problems as my car was mapped without one? N75J or N75race?

Guys, gonna get a new n75 today... There's a local VW garage round the corner from where I work- can I get one from there or do I have to go to Seat? Also, does anyone know the part number? Many thanks, Rhys

Been reading on uk mk1v website about n75 replacements for the 1.8 turbo engine. Changing the valve for a different spec is giving in some cases another 3/4 psi. Anybody know if this can be done on the pd150? Glynn

Ok so I got my N75 race valve yesterday. 1st thing is, is anyone running one of these? And if so did you fit it yourself? Any problems to look out for or an easy job? 2nd thing is I think these valves are illegal for road use. The sticker on the valve says for Off road use only...

Was just having a nosey in the Mk3 section, and they are taking about changing the n75 valve. Anyone done this on a MK4 yet?

as above really, been told there is different version's of the n75? how would i know what one to get as a replacement or which one is best to get?
