GTI 337/20th Anniversary :: 2004 1.8T - Half Throttle Boost / Little Hesitation At 5 PSI
I have a 04' Jetta 1.8T (AWP) my mods are APR Chip (91octane program) Forge 007 DV, APR TIP, NGK spark plugs, catback exhaust. This issue I am having pretty much started when i got it chipped and I've got it reflashed and I've even talked to people at APR and they are saying that it couldn't be a software issue. Anyhow the problem I am having is at partial throttle my car kind of hesitates a little at 5psi and when i let of the gas the car kind of hiccups a little.. but if i really punch it in every gear i hit 21-22psi no problem, the problem happens when I am driving normal and its really annoying.
I have switched several different N75 valves, I am running the stock one now, I've switched different DV's, i have switched my spark plugs and even put at APR turbo inlet pipe and i have checked for boost/vacuum leaks, I have no CEL...all this hasn't resolved my problem.. I don't know what else to do..
I was thinking about switching my MAF to see if it works, but then again if it was my MAF im sure I would have a CEL. I also was thinking about putting my N75 valve backwards even the DV backwards to see if it works?

Recently purchased a 2005 Jetta GLI with 31,xxx miles on it. It is my second 1.8T. My first was very reliable, with never any issues even after the 100k mile mark and is the reason I didn't hesitate to buy another one. That, and the Recaro Edition GLI has always been one of my favorite cars.
So I've had it for about a month now and I've noticed on occasion a problem with cold starting. One weekend it sat for almost two days because we used our other car, and then again this morning it was particularly chilly here in Pittsburgh, about 35degrees F and it took me two starts to get it going.
I always turn the key to 'on' for a few seconds and let the fuel pressurize and all the indicators light up. It doesn't appear to be the battery as it turns over strong, though I have not yet confirmed this is a Voltage reading. Once it kicks over, it seems to be choking or sputtering, unable to get up to idle. The second time, it does it again but gets past it and all is well...
I'm checking records now to see if the 30k mile service was completed. perhaps a tune up and new plugs would work?
GTI 337/20th Anniversary :: Hesitation After Intercooler Install
Last week I had the Godspeen intercooler installed on my 05 Jetta GLI. I would say that since the install I have put about 300+ miles on the car so I would think that the computer has learned the additional air flow. I notice that if I'm cruising in 4th gear just below 3000 RPM's and punch it there is hesitation. It is quite noticeable because I have a full 3" inch exhaust so you can hear it hesitate for about a second and then kick in again and continue up the powerband. Do I need to get a good tune or has the computer just not learned it yet?

I have a 377 gti 2002 and just the other day i had some hesitation on take off. it sounded like the engine was cutting the fuel, at the time i had an o2 sensor code so i replaced the o2 and got new spark plugs while i was at it. it was still hesitating and cutting out so i figured it might be the maf because ive already replaced it once, i cleaned it and still doing the same things. i called my local vw/audi shop (audub) and he said it might be the pcv valve. i checked to see if there was air sucking in through the oil dip stick and the oil cap. its running just fine at idle and it seems that in first and second gear that its hesitating at 1000-2000 rpm and the higher gears are fine. could a leak cause this or is the pcv system bad?

I took my car in for a clutch install, everything was fine except the clutch slipping. I go to pick up my car and once the car warmed up it started bucking / limp mode while accelerating. Take it back to the mechanic and he thinks he didn't reset the throttle body. So he says that should be it and I pull away. Same thing. Leave it with him again and he replaces with "diag" coils and new plugs. Leave again, same thing. He tells me to get totally new coils and try that. I am thinking its a missed ground cable or messed up ECU or something. During all this not one code it thrown.

GTI 337/20th Anniversary :: Hissing Noise When Let Off Throttle
So, when i throttle down i get a hissing noise, almost like a very small jet engine. then when i let off the throttle I get the psh psh psh psh noise and not the solid pssshhh noise. What might it be? I was thinking pcv breather, or DV, but i dont want to go just replacing parts. I have the 04 gli 1.8t ....
View 2 RepliesGTI 337/20th Anniversary :: Car Sputters Around Half Throttle / 10 PSI
Yesterday, I was taking off from a light and noticed that when I got around 10 PSI, the car kind of nosed over and sputtered. So I started to play around and discovered that no matter what gear, this always happened between 7-12 PSI of boost. Normal driving for me is shifting around 3k RPM, about half throttle. Sometimes when I shift, it pops. Not like a normal, chipped car pop but not quite loud enough to be a backfire.
I took my dad out in the car and got to 55 MPH, then held the throttle half way to keep boost around 10 PSI and it would start sputtering/bogging down erratically. Any more then 12, and the car is fine. Any less then 7 and the car is fine. He suggested a Throttle Position Sensor that has a dead spot in it.
Here's some thought from me:
Coils/Misfires - If it were a coil or misfiring, it would be all the time, not just what I described above, correct?
Boost Leak - At WOT, the car gets up and goes while holding steady boost.
Vac Leak - I've been told at idle, the car is supposed to have 19-21 in Hg of vacuum. It's at 20.
If you turn your speakers up, you can actually hear the exhaust gurgling in the video when I hit the spot I am talking about. There are no loud noises, so don't worry about maxing them. I had to.

GTI 337/20th Anniversary :: 2002 VW Automatic Shift - Slight Hesitation When Slowing Down
I have a 2002 1.8 Turbo VW GTI. Lately I've noticed that the car would hesitate slightly when slowing down. It would go up to at least 5000 RPM's or higher before it shifted over. The hesitation when slowing down and accelerating tend to happen when I drive. What to do, I went to the vw company they said if i want to change the transmission would cost me ~6k$ and f*ck me twice if if am paying 6k on a 2002 car.

Getting onto the freeway, not putting the gas to the floor or anything, my throttle completely cut out on me and the EPC and ASR light came on. Turned off the engine, let it sit, and it fired right back up with no lights on.
Replaced the valve cover gasket recently and had a somewhat rough idle since, not sure if the coil over isn't all the way down but will investigate soon.
GTI 337/20th Anniversary :: Partial Throttle / Surging Usually In 2nd Gear
I've noticed this when driving for a while now but was never really sure what was causing it. It was usually in 2nd gear and the car would sorta surge on and off boost almost. yesterday i found out that it only occurred when i gave my car partial throttle. It would build boost, let off, build again etc. Full throttle and it was not a problem at all. My car is an 04.5 GLI chipped / 3" exhaust etc etc and would like to know what I can do with this problem.

Mark IV GTI. Neuspeed intake, chip, exhaust. The situation is...
When driving enthusiastically, harder, and sportingly, the car runs beautifully!
When driving normally, such as highway cruise or lower speeds with a consistent throttle input, the power will cut-out. Then the max boost pressure will be approximately 3 psi until the key is cycled. Then normal chipped operation resumes. Since it is difficult to drive hard all the time, this circumstance comes up often.
There is a new N75 recently installed. The situation does NOT set off the check engine light.
I have noticed according to the boost gauge readings, it tends to happen between 10 inHg to 0 psi. Above or below that, don't recall it happening.
Touareg :: TSB For Throttle Hesitation Downloaded, Car Won't Start Now
Took my 04 V8 in Monday AM for airbag fault, throttle hesitation, and remote key fob/keyless entry range (lack thereof). Called the dealer yesterday and service rep says airbag and remote range fixed OK, but after TSB for throttle hesitation was downloaded, the car would no longer start. Service rep explained that the shop foreman had worked on car personally for most of day and still was not able to start car.

GTI 337/20th Anniversary :: CEL On - Car Shut Off Now Won't Start?
The car is a 2004.5 GLI 1.8t. My car threw a CEL about two weeks ago. When i ran the codes it had one for the camshaft position sensor, one for the secondary air injection, and one for the camshaft position sensor. I cleared all the codes and the light came back on. The only code that came back was the camshaft position sensor P0340 i believe. I drove the car for a week and out of nowhere it just shut off on me while driving.
All the lights on my dashboard were flashing (traction control, battery light, engine light, etc.) I tried to jump it just to see if it would turn over and still nothing. I rolled it down a small hill and tryed to pop start it...still nothing. So I had it towed to my house and I replaced the cam position sensor AND the crankshaft position just to be safe. but now the car still won't start...
The engine is cranking and you can hear the pistons moving but it just can't get the juice to start. After failing to start it 3 times, i noticed a loud vacuum like noise coming from the engine when i turned the key off...but my car would do that every other morning when it actually started and didn't have the CEL, and then once it warmed up the sound would go away.
GTI 337/20th Anniversary :: Car Randomly Won't Start But Cranks
So my 20th randomly won't start. It's happens about once a week or so. Most of the time when it happens the car cranks but doesn't start. Every once in awhile when I turn the key nothing happens at all and I have to keep trying and it'll crank and turn on. I also have no way to check for codes
View 6 RepliesGTI 337/20th Anniversary :: Have Fuel And Spark But 1.8t Won't Start
I have a perplexing problem and I'm at wits end trying to figure it out. I have an 03 GTI 1.8t 20th. The car has been running great until today when I replaced a few bolts with the front bumper and replaced a motor mount bolt on the passenger side mount. Everything was great until I did the work on it. I figured I had bumped the cam position sensor so I swapped it out for a new one and nothing still. I have verified I have spark and I definitely have fuel as it keeps drenching the spark plugs. I have cleaned the spark plugs and tried starting only for the car to violently sputter and misfire. No codes are being recorded and nothing else has been touched.

So I just recently got a 2005 GLI and I have been taking care of all the maintenance first before I start modding it. But there is one thing that I can't seem to figure out and I have searched but can't find this exact problem anywhere. My problem is I will have to turn the key several times before it starts, it does turn over but will not start until about the 4th or 5th attempt. This will happen maybe once a day but sometimes it will be fine all day long. Also the ESP light comes on once the car starts but doesn't come on if the car starts normally. Now I have seen people saying ABS/speed sensor might be bad if the ESP light comes on but mine isn't always on. Just when I have trouble starting it and then it goes off once I turn the car off and back on.
For those that don't feel like reading:
- Car sometimes (once in a day or two) turns over 4,5 times before it starts
- ESP light comes on when it has trouble starting
And of course, here is a picture of the new-to-me ride .....
