I don't think anybody in the UK supplies this valve.
I got mine direct from ECS in the US, no problems and it arrived within a week.

is there a website i can get on and order the part ?
http://www.ecstuning.com
I don't think they have an online ordering system.
Send them an email, they responded quite quickly but give them 24 hours or so to allow for the time difference.

Give Jabbasport a phone , I think there do something like this......
dreamer: are you happy with your ecs valve?
Yes, very happy. I wanted boost on my car to hold higher up the rev range which is exactly what the ECS does. The valve seems to have smoothed out the delivery of boost as well which makes the car nicer to drive.
Possibly a better way of controlling your boost though would be to fit a Dawes Device (http://www.dawesdevices.com/). This eliminates electronic control of the wastegate by the ECU and doesn't throw any CEL's or codes. A number of Impreza turbo owners use these with good results.

The davesdevices stuff looks sweet. I exactly had the same in my mind when using the car N75 less (due to testing) - it could be light years better than the stock setup (preventing the ECU to generate flat spots & slow response all the time). Pretty cheap too, though bypassing the N75 would probably make ESP/TCS not working properly anymore.
It may cause a problem with ESP/TCS etc. but I think the ECU controls the DBW throttle/fueling and the braking systems to stop wheels spinning etc. The ECU controls the wastegate (via the n75) only to regulate boost and cut it during an overboost moment, so ESP etc. shouldn't be affected by adding a Dawes Device.
... yes but as far as i know, when ESP/TCS cuts in ECU reduces boost via the N75 too.
My idea is to get a "Dual Stage Control Solenoid" (also from dawesdevice) which you can use to switch between the original N75 and a Boost controller to have two different setups. OR get two of the Control Solendoids and have three different configurations (selectable in real-time from the c-ockpit).
what is a dawes device and what does it do ?

Good explanations on there.

Just want to add that when i "adjusted" the N75 valve, my TCS went out.... So now I have the lamp lit all the time, and the 1551/1552 instruments reads that the TCS is functioning alright but the MAF-sensor is corrupt. Which I (probably) would have noticed speeding away from a couple of AUDI S3 :D .
So it's a Catch 22.... I adjusted the N75 valve, got a malfunctioning message that the TCS is out of order, but the SEAT guys reads from their instruments that the TCS is working but the MAF-sensor i out of order, but the car i responding like it should.
Anyone??

Have you checked the connectors on the n75 and the MAF? If I unplug my MAF then my ESP light comes on. It's worth making sure that the connectors are pushed in correctly.
Anyone here running a dawes device yet?, or am i set to be the guinea pig again :D , looking at ordering from the US as their prices are significantly cheaper over there and i dont mind waiting a few extra days
Go for it Mosser, I might fit one if you get good results with it. The ECS n75 is better but I would still like more control over the wastegate.
A friend of mine is installing one on his scooby soon which is currently electronically controlled in the same way as the 1.8T, I'll let you know how it goes.

since i naffed my original C version of the N75 i have been getting major surging and it is starting to get really annoying, i dont want to get Upsolute to come up with a fix as i am running their 1.3 bar version of their chip and dont want to go back to a standard 15psi boost now!!, Amethyst fitted an F version and they seem to be getting chip unfriendly nowdays, i cant see them wanting to help me out by swapping it for a C version so the cheapest solution for me is looking like fitting a dawes device, might not be keeping the car for much longer anyway!
Hmmm, now i'm thinking fo getting an ECS N75 instead from the US !, Doh, dont know which would be better now! anyone got any ideas?, is the ECS N75 adjustable?
ECS n75 isn't adjustable. The screw that can be seen on the standard 'c' and 'f' types is blanked out on the ECS.
Mosser, I did try to send a PM in reply to you the other day but your mailbox was full.
The ECS has done a god job on my car but I never bought it to cure surging as I have never experienced surging in my car, I'm also running an AmD remap as opposed to Upsolute so that could make a difference on your car.
The ECS n75 is more expensive than a Dawes and isn't guaranteed to fix your problems, the Dawes will almost definitely fix the surging as it removes ECU control of the wastegate.
i have emptied out my inbox now, i only had 6 messages in it but it seems to save sent messages as well for some reason!!,
I never experienced surging either until i got an F version of this valve, it has always had silky smooth but very powerfull power delivery, now once past 2nd gear is just pulses the power on and off whick is retarding my ignition on each pulse and reducing my power, i'd be lucky to keep up with a 323 now let alone outrun a 330 !!! and it can be seen on my vag-com dyno plots as a saw tooth form!
What version were you running beofre you get your ecs one?, how did the ecs one do a better job?, more power?, quicker delivery?
I was running a 'c' before. With the ECS there seems to be a slightly longer delay before boost builds but once boosting, the car feels slightly stronger and boost is maintained higher up the rev range before it starts to drop off.
so, its souunding like the dawes device is going to be my best bet then, i will email the US distributor and check with them and will let you know what they say
the guys from upsoloute have since been out and hooked my car up to the vag com and had alook at my e.c.u to see if i have any fault codes on it ...................................
it did 2 off too be precise
one for the diverter valve and the other for a flat battery !
im gonna replace the stock diverter valve and see what hapens
gonna try the forge motorsprt dv007 p
will let everyone know what and if there is any improvement
just installed ecs n75 valve, great mod.. just 2cents from me
