GTI 337/20th Anniversary :: 1.8T Cold Start Hesitation - Choking And Sputtering
May 18, 2009
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?

So my car is throwing a P0172 and when I start to get into the throttle, I get hesitation. I have replaced the plugs and the coil packs, and I tried unplugging the MAF which just made the car run worse. What could it be? Boost leak? Something else?

Having issues with turning over but no start, sometimes takes up to five turns to start up, and hesitation on hwy in 6th gear. Fuel problem im pretty sure.

I get EPC and ASR upon cold start from time to time. Usually EPC goes away if I restart in a couple of minutes. ASR goes away after a while and restart.
So after car warms up and restarted, everything seems fine.

Revo stage 2 --1.8t ... For the past few days I have tried to figure this issue out I am having with my 337. The car takes 2 or 3 times to start from being cold. Once its started it has no issue it drives awesome, pulls hard no codes when vag com'd. Can start it up anytime with ease for the rest of the day. Tried doing to solve:
-I have pretty new coilpacks---FSI- they are ok
-Spark plugs are 3 months old --checked those
-Checked Battery and its all normal and no issue
-Cleaned the throttle body = No change
-Installed new CTS yesturday (green) < no change
-Cleaned the MaF = NO change in start up but car runs way smoother
-Put in new Filter= No major change
-Did the Crank sensor under a month ago (Bosch)
I have a few more things on my list to check :
1. Fuel pump relay
2. Fuel Pressure Reg
3. ECU relay/ check immobilizer
4. Fuel Pump

Well I didn't drive my 20th this weekend, and this morning when I left to go to work it was kind of sputtering when i pressed the gas, and when i stopped the CEL flashed, which I know means its a mis fire. But then turned off so I kept going to see if it would happen again, It didn't, ran just fine no sputtering or anything. Question is, what would cause this to happen?

I recently got a 2002 gti 337 from some dude in maryland. the car had apr stage 1 and 2 installed and a euro tuned air intake...everything else was stock. I've had the car for about 2 months now and all of the sudden it started sputtering and cutting out when id get on it a little. I also noticed I was smelling a lot of gas from under my hood. i read up and found that my car had a recall on the coilpacks so I just got them replaced thinking that would work..then changed the plugs as well. i still have a misfire though only in cylinder 4 and its really taking the fun out of the car. I only have it on stage 1 because I didn't have a turboback till just recently and now I don't even want to put it on cause i have no power.

Have a little oil on the outer part of the turbo and its making a raspy noise when my turbo is spoiled not sure whats going on the car pulls just as hard and boost levels are normal i had a check engine light on for a few days right after this started code was for p0411 dont think its related cause i know my secondary air pump whistles at cold start so im assuming that the code is for that and not related to the turbo.

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.

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?

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.

The A/C hasn't been working for a month now, won't blow cold air. Took it to the shop and they put 1.5 pounds of freon in it. But it still won't blow cold. I'm taking a 1200 mile trip in it soon and the shop isn't an option. There's no leak as of now. What to do?

Got some issues going from first to second when the car is cold. Kinda feels like it grinds not sure if it is or not. When it warms up seems ok. Changed the fluid, smoother but kinda worries me.

so another winter has come to me in michigan and i had to take off my nice performance tires and put on the winter steelies. but as i come to now with them on, my ESp light has come on, on my dash and wont turn off even if i reset the car. i havent checked the VAGCOM yet cause that laptop is at my parents. the tires are the same i used last year and didnt have this happen either. any thoughts on this and what could be wrong? haveing no traction control in the winter is not cool to have in my book.

What would cause a sputtering noise to come from the engine but only after a cold start meaning starting in the morning and after work but goes away after I drive for a min or two and doesn't come back until the next morning or after work. It sounds almost as if say you had a hole in your flange and drove it around. Its really weird it happens a few times a week for the psst 2 weeks but hasn't happens ever before that. Could it be the water pump in its way out? Oil levels fine fluid wise everything topped off.

It all started after it being cold outside it's hard to shift into second gear when i first start up the car, and then after a couple shifts like that i get a notchy shift. after a while of driving it all disappears.

Here's my issue: as it gets colder out, I ride with the windows up, so all the little squeaks and creaks get that much more noticeable.
Ones in particular that drive me nuts are the squeaks that originate from the rear deck area (almost as if they are coming from the rear upper shock mounts between the C-pillars - I think this is a Jetta-only issue). I had a c-pillar bar in the past and it seemed... but the bar is a tad unsightly, and it rendered my rear seat belts useless.
Need finding and eliminating these noises in the back? I'd rather not run one of those bars again if at all possible.
