n75

After only misfiring at idle for about 3 seconds a month ago, my Leon 20VT now seems to be doing it constantly and also not being too smooth when pulling away with little throttle. I've searched the forums and found advice on it being the N75, Coil Pack, Lambda sensor or Re-Circ valve. Is...

just wondered what the signs are for these as im having trouble with boost. the car just feels like a 1.8 not boosting above 5psi at times? Other times it feel like its hesitating then hits you with full boost , not a smooth delivery??? Had a look at the N75 at the number on the side which...

Seem to hae boost issues... car used to run side by side with my mates cupra that i know for a fact boosts 8/9 psi, mine died down to 5/6 so i got an n75F thinking it may be the difference, one way it only boosted to 6 still so reersed it and found it boosted properly.... thing is it sometimes...

What is the difference with all the different n75's all about??? i was reading a post in the vag com section and 'cupra t girl' was mentioning different n75 valves.... just after a bit more info people! Thanks Ads:)

ok i swapped my valve for somebody elses, and seems to make a difference. Mine is still hesitating etc.. I have a "C" Valve, Mikes was an "F". Immediatly boosted to 7 not 6psi as before on stock. and currently i do see the boost gauge jumps slightly when at full boost, and also goes to 4...

Hi there, I have just changed my N75 valve as I was having fluctuating boost probs, since putting the new one on my car seems more hesitant and is not pulling like it should, the turbo does not seem to be spooling up properly. what could be the reason for this, I thought it would run better...

Hi I posted a thread a few days ago about my car having intermittent episodes of feerling held back. I have dedicated this weekend to trying to get closer to identifying the problem. Initially the thoughts were that the MAF may have been the problem but my findings today may point to...

hi guys does anyone know where the cheapest place to get one from because mine is dead! thanks daz

Popped out last night to do some logging as I was a bit bored.... First Log - Blocks 002,004 and 115. http://www.seatcupra.net/users/martyn/logs/First-002-004-115.xls Second Log - Blocks 002,115 and 118 http://www.seatcupra.net/users/martyn/logs/Second-002-115-118.xls N75 duty look a...

Was just wondering about this,the n75 duty hits 95.3% max in a attempt to spool up fast(requested boost alot higher than actual) then duty levels out to between 70-90% till redline is this correct.Boost seems to be a touch higher than requested.

Does anyone know if this is the part number for a N75 J valve? 1J0906627? also would if be a good?/bad idea to fit it to my ibiza? Thanks

Hi im new to this forum and have recently brought a leon cupra, its standard apart from a forge 007 recirc valve and a boost guage, but i have a couple of problems with it. Every now and again the car just stops boosting to its standard boost about 8ish and drops down to 4psi ive done a...

Recently, my car went into I believe limp Mode or boost spiking what ever Mike called it at Jabba. This was noticed when I was doing more than the legal limit up a long incline stretch on the A1. The car just felt like it hit a brick wall - the car was under load clearly. It was that bad I had...

what will happen if you drive with the n75 valve disconnected? (the wires i mean?) Cheers HoocH

My Ibiza came with a C, but ive also used a J. How does the F differ from these two?

below is 2 power runs, ran consecutively with ample cooling fans on the go. the higher figure on the dyno sheet was with the n75C which seems to come in and hold onto power earlier than the J valve which ive just removed due to stage 2 not liking it. I still think im losing power somewhere as i...

Hi all, I've spent ages reading all the threads on the N75 valve, & I've learned a lot :clap: , but I still have a couple of questions I couldn't find a definitive answer to. Is the 'F' variant the standard one on all 1.8t engines, or just the Leon Cupra? Would a faulty one always...

Ok wat is this valve for ? lol ima new to this engine and why u ppl changing it? :confused:

Can anyone explain or show pics of how the standard N75 valve should be fitted, and how the N75J valve should be fitted? I've read the J should be fitted the opposite way to the standard N75. Think my Cupra went into Limp Home mode last night so i want to take the J off and replace it with...

Found this on 20VTurbo.com ... Here goes.... As i see many of you are totally confused about the N75 valve (what it does, how is it working), just exactly as i was before digging myself into the topic quite deeply. My car was seriously down on power - i even posted some desperate topics here...
