    Hi everybody first post but have been reading a lot here. So as the title says I'm getting this code after putting in a brand new oem replacement turbo. I broke the T off of the n75 valve when I was talking the old turbo out so I got a new uro parts brand n75 to put in it. After I got it all...

    I just replaced the engine and transmission in 2006 Passat value edition 2.0t . Runs great just no turbo boost whatsoever. I need to know what fuse power the n80, n75 and n249 valves. I know the 480 relay is on this circuit but the fuse that powers it is blown. Thanks in advance!

    Hi Guys I am a owner of a 2006 Passat Value Edition. Recently I replaced the engine and transmission. Now the n75 n249 and n80 have an open circuit. I need to know what fuse powers this circuit. Thanks in advance!

    Hey hows everyone doing, Yesterday I got my 2002 b5.5 Passat flashed with Unitronic's stage 2 software, and the power increase is insane, but I think something isn't right. This tune, according to uni, is supposed to make 18psi, I don't know if thats the spike or hold psi, but I think its...

    Can it be done? Not looking to increase the boost at this time, just looking to do some curve tweaking. Thanks.

    So here begins my epic tale of woe. Back in June I decided that it was time to buy a new car come the fall, 2008 VW R32. With this planned all repairs on the passat ceased to allow for proper money saving techniques to be employed. Additionally I had just got my motorcycle license and my first...

    Hi all!!! About a year ago I got an APR tune for the car. As I pulled out of the lot I was at 23 Psi. (yikes) Installed MBC to limit boost same day:wrench:. (Now range is 9-25 Psi) Yesterday the car changed something with Boost Pressure Control. No matter where I am in my MBC settings i have...

    I bought this valve and couldn't use this with the tune I have. Giac (PC-16) file. There's seriously not even 2 miles on it. I have the receipt from last month still too.This valve makes boost come on sooner and smother than the c or f valve. Also it increases the psi by 1-4 higher and hold...

I dont have vag-com but i have access to ODIS. I went to test the N75 valve and ODIS asks if i can hear and audible clicking noise, nope. I...

    Just purchased this on ebay, turns out my problem was a boost leak not the n75, so this is now for sale.

    MAF and ICM sold! No picture of the N75 valve. It's the regular stock one. Worked when it was taken off about four years ago, found it in a box o parts and has over 100k on it. Probably the 110-120k range. Some corrosion on the metal bracket on it, nbd though. Asking for $20 shipped.

    Can the N75 valve be tested with a mityvac? I've done a lot of searching but no one confirms that this valve should hold vacuum or pressure. When I test mine with my mityvac, it leaks down very quickly. Is my N75 solenoid valve defective?

    What are some symptoms of a bad n75 valve? Im experiencing a problem where sometimes when i step on the gas WOT im not getting full power but if i fully let off the gas then step on WOT again it will have full power. Its very strange. Im thinking it might be the n75. I dont think its a boost...

    Does anyone know what the adjustment screw on the N75 boost control valve is doing? What it actually changes? What the effects are from turning clockwise or counter clockwise? I would like to try to 'de-adjust' my current setup since the combination of larger turbo, N75, wastegate...
