Golf IV / Jetta IV :: N75 Valve Connection - Boosts Inconsistently
Sep 24, 2016
I bought a Jetta 1.8t few month ago and a hose is missing on the n75. The car run great but it boosts inconstantly (someday it boost at 16 psi peak and another day it doesn't pass 10 psi). Today I bought a hose that I connected to the turbo inlet pipe and now it never pass 10-11 psi. Did I do something wrong? Or my car isn't chip and the previous owner did that to increase the boost?

I just finished my first MK4 steering rack replacement (don't work on too many VWs), and when I placed the steering shaft from the column onto the shaft from the rack and bolted it down, there was still some clearance (see photo). I was able to get the bolt tightened down ok, but the clearance is bothering me.

I have a new hose I need to install because the one on now is cracked... I have pulled the metal clip down, but how do I remove this so I can install the new one? I don't want to break anything else yanking on it too hard.

2010 VW Jetta Sportwagen TDI -- manualOne owner.No repairs in history of car. Regularly maintained at dealer.
From beginning about 1/month will be driving ~30 mph in 3rd gear when car seems to hiccup once before returning to normal operation. Does not seem to have any repeatable attributes. Only seems to happen when about constant velocity with very slight acceleration.
Dealer says computer doesn't show anything and of course can't replicate.

Is it dangerous to the car to drive if the wire connection is broken to the camshaft timing oil control valve? It seems to run fine.

Just got this vr6 a week ago and noticed what sounds like a valve clicking, I thought maybe it was low on oil or something, so I just changed the oil and filter yesterday, clicking was gone from what i could hear. Start up today to go to work, clicking is back, I've noticed after the engine heats up the clicking subsides, but when you first start up I'm hearing it tick in the same area. Thinking maybe a intake/fuel cleaner next? My other 24v never did this. I've never taken it over 3k or anything until after it's warmed up.

Replacing a heater control valve for a 2004 Jetta? My car's vents only blow hot, and I checked the cables and saw that the control arm was disconnected. I tried to put the cylinder piece back in and had some luck, but I can't get it to sit tightly in there and it keeps falling out. Also, it still wont change the temperature coming out of the vents. I assume that something broke on the inside piece that the cylinder connected to.

Here is an example of what mine kind of looks like, but mine is way more loose.

I drive a 2003 24V VR6 GLI
I recently did a valve cover repair to stop the dreaded misfire problem. Well, I'm still waiting on a few things but during the spark plug change obviously some of the oil from where the valve cover leaked previously fell into the pistons because I couldn't really clean it all out efficiently. This seems like it would cause a lot of problems? Do you think I should throw old spark plugs in there and let all the oil burn up before finally replacing them? I really don't want to foul up my brand new NGK's.
Also, I pulled p0300, p0305, p0306, so I am guessing oil in the spark plug/coil pack connection may cause some of the misfires, but do you think two of my coil packs are bad still? My plan was to move them around to see what happens after I get the new parts and am actually running again.

I have a 05 GLI and I noticed that on the stock "E" valve my car would get random boost surges. I would barely tap the gas and the boost would build up to 8-10 PSI so I bought the J valve thinking it would solve the problem and just installed it today. I took it around the block and really liked how the power delivery became smoother and the car didn't have any boost surging issues. When I decided to put my foot down I noticed my car was only getting 11-12 PSI throughout the whole power band. Before on the E valve I was getting 16-17 PSI. My car's running a Unitronic stage 2 tune btw. I know upgrading to the "J" valve is a hit or miss but I think it's kind of odd that the car drives smoother but isn't running as much boost. I like how it feels for daily driving but something doesn't feel right.

I did a valve cover gasket replacement. Changed all spark plugs and coilpacks. The car is still misfiring. I also just did the timing belt and water pump. Why it's still misfiring?? I'm new to this whole forum thing so bear with me lol. I'm wondering if it would be my cat, fuel pump, fuel filter. Or could it be a sensor?

I'm thinking of purchasing a 2001 GLX VR6 Jetta with lots of deferred maintenance (shocks/struts, brakes, exhaust). Most worryingly, the valve cover gasket is leaking oil. The price is pretty low, but is such a beast worthwhile at any price or is it better parted out? And the interior is about as beat up as the mechanical--screeching passenger window motor, broken glove compartment ... Is this thing worth being brought back to life?

I know this isn't the usual ticking of the injectors and I believe it's to fast to be a lifter tapping. I believe it's the camshaft chain hitting against the valve cover. I took the valve cover off and the chain is still tensioned tightly so it makes me wonder what this could be..

In order to replace the valve cover do the spark plugs have to be taken off ?

My mk4 sat for a while and upon starting up was misfiring. I checked for pvc leaks and didn't see anything but went ahead and cleaned my maf sensor and decided to pull my coils. Cylinder 1 had oil on the tip and around the spark plug which to me spelled out a bad valve cover gasket. I got all the parts to do the inner and outer gaskets and replace the coil and spark plug, however we got a snowstorm and my luck a rabbit got in and ate the wiring on one of my fuel injector connectors.
So went ahead and put on the new gasket, replaced the coil and plug and bought a new Fuel Injector Connector and spliced in onto the Injector "Pigtail'. I double checked everything was reattached properly and let the gasket sealant dry for 24 hours. I went to start it tonight and after trying to turnover it completely cuts out, wont even start up. I'm extremely frustrated at this point and am thinking the rabbit must have gotten to something else unless I did something wrong in the process of repairing.

So the other day I replaced my N75 valve and upgraded my DV to the Forge 007. For some reason the turbo doesn't spool like it did before, it's lost it's pep.
I've tried the Yellow and Green springs, also I tried them with the shim too. No luck. The car got turbo back exhaust, intake, and stage one program.

I recently put a cold air intake on my car and I could hear the dump when I let off of the gas. But I also put in a boost gauge but I think I had a leak in the hose going to the gauge. After I drove it for awhile the blow off valve started making a flutter noise when dumping. I fixed the leak in the hose but the flutter is still there. How do I fix the flutter? A new blow off valve? Mk4 Jetta 1.8.....

Question, I have a 2003 VW Golf GLS 2.0L AHV (5 speed). The brake vacuum line is cracked after the check valve on the intake side. I looked up the part number on the hose (at work and don't have it on me at the moment), did some research and noticed some revisions to that part number. Eventually settled on [URL] ..... (I ordered a new one since I needed to order a few things). Needless to say, I am beginning to think I ordered wrong.
I noticed that the check valve on the new hose has a 3rd piece that a smaller hose looks to clamp on? The check valve that is in my car doesn't have that. Did I order the wrong part? or did I need to be a cap?

It makes a weird 'fppp' air shooting noise before the exhaust note and my 2003 gti vr6 makes the exact same noise. It sounds like it's coming from the intake manifold valve and not really the filter, but I'm not sure and yes my filter is clean, the noise also sounds a little bit more obnoxious and problematic in real life. What it is, I thought it was a vacuum leak but I don't wanna bring it in till i know exactly what it is,

When driving the radio will occasionally suddenly come on very low and then the volume will build. When the car stops and the ignition turned off the radio will not restart when-when the engine is restarted. There are times the radio will not come on for weeks.
