GTI 337/20th Anniversary :: Stutter During Acceleration On Highway
Feb 26, 2013
I was driving the other day and accelerated in 5th and the car stuttered before finally going- I got the flashing CEL. I figured that the car was misfiring and that a coilpack change was the culprit. All my coilpacks are fine and the sparkplugs look good as well. CEL hasn't come back, but the car just feels like it doesn't want to go right away when if i give it some gas when I'm going about 55-65 MPH.
Other guesses would be there is a fuel cut somewhere and that may be causing it?

So over the past couple months when driving on the highway I would notice that sometimes my car would lose all power and slowly coast to a stop, but then the power comes back on and I'm off after a few seconds. It happened again today and I notice when I do hit the gas when it decides not to accelerate my boost gauge shows that there is vacuum building up in the engine. It just doesn't make sense to me. Would my car be getting thrown into a limp mode? Or is it something to do with fueling?

I have a 2003 20th anniversary edition GTI. Yesterday I noticed my car started shaking when I was driving on the highway. The only thing I can think of that I did was run into a snow bank during the snowstorm. What is causing my car to shake?

50k Miles on my clutch. Was driving a couple weeks ago on the highway and clutch stuck to the floor. At first I thought it was my Slave cylinder. Got the trans out this weekend to find the mess (below) inside my bell housing. Obviously need a new clutch now and will still replace the slave while I am in there.
Cars setup is around 375ish whp. I know I could spend 1300 bucks and call it a day for a clutch master or south bend but was seeing if there is a cheaper alternative.
Also If I were to buy an OEM clutch or an upgraded one that was not rated for up to 400~whp would it drive and pull the same as a fully upgraded one just not last as long?

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.

So driving on the highway my car died. It would crank but not start. Got it towed. This is what I have done to troubleshoot.
1. Swap ECUs. The car should start for a second and shut off because the car doesnt match with the ECU. Still just crank and no start.
2. Fuel pump still primes when I open the door. I also hear a weird air leaking noise when I reconnect the battery, but I think it comes from the fuel pressure regulator (which I think is normal).
3. Checked for current at the ecu wires, wasn't sure what to look for but it was getting numbers.
4. Battery had 12.1 volts running through it (Haynes said 12.5 but is that really much of a difference?
5. Checked spark plugs for spark. Pretty sure we did it right, but there was still no spark. We tried multiple times.
6. Scan car, get code P01314 twice (ECM error).
7. Try to clear codes, says Comm error.
Why am I not getting spark? and why is the ECU error occurring, because we tested with a new ecu, and there was still no start, not even for a second like there should be.

So I was driving on the HWY in 6th gear cruising at about 60, and I go to speed up and when my RPMS hit about 3k or over it feels like I am pressing in the clutch, like my RPMS are going up but I am hardly gaining any speed.

I have recently purchased a GLI and am in the process of resurrecting it. One of the main issues I am having is when I get up on it during acceleration I start to feel a strong pulsing. I have found that it only will do this in hot weather and it does it in every gear. I work at a volkswagen dealership and have asked other technicians if they had any clue and nothing. I am going to have a pressure test done to it to see if it could possibly be an intake problem. Everything on the car is stock and I don't want to upgrade anything until I figure out what this it.

About three nights ago I had a complete power loss on the highway and the car began to bog down alot under throttle (and surge at points as well although with no boost). It also idled very rough/erratically. When I unplugged the MAF it cleared up right away; Idle was smooth and it ran without hiccup but in safe/limp mode so very tame (again, without boost really, gauge shows it stays in Vacuum and never passes "0" or goes into boost).
I scanned it this evening and got 2 misfire codes and a MAF code, along with a code related to traction control which I noticed had activated as a result of this and could not be turned on (by activated, I mean the light came on, disengaging T/C). These things make me think it is MAF related, especially because I have bolt down Hitachi coil packs so I do not think that is what it could be in relation to the misfire codes (which I think may be old and needed to be cleared).
Fast forward to last night: I can pretty confidently say my MAF is not the problem and I think I saved an unnecessary expenditure. I was able to meet a friend with a 337 as well and his MAF did not change my car at all and my MAF ran fine in his car so I think my problems are something else. Although with the MAF plugged in my car runs very poor and unplugged it clears up and just runs "limp" (no boost and slow but stable) from what I tested this evening the MAF unit seems to not be the issue.
I think there must be a vacuum leak of some sort between the MAF and the engine which allows more air in than the MAF signals when plugged in which causes the issue. Also, I know a common thing to think is "coilpacks" but I have bolt down Hitachi coil packs so I would imagine that would eliminate those from being the failure they tend to normally be. Agreed ??

I got my 2005 jetta gli used with about 41000 mi on it. Ever since i've had it, when i accelerate on the highway at 50 mph or faster, the car almost feels bouncy throughout, what that is.

Start with the basics, no CEL's, car has not cut out while driving and I've only had to attempt cranking up the car twice since I started noticing these issues about 6 months ago.
Symptoms: hesitation/variation in boost during acceleration- doesn't matter if I really get into the gas or just "normal" passing acceleration RPM's steadily climb, but just not as consistent or quickly. Also, the one that really has me really confused. With a 1/4 tank of gas or less, going up a slight incline (overpass); 70-mph-ish... acceleration dies off, rpm's slowly decline, and gas pedal doesn't respond for about 2-3 seconds. Car never shuts off, no CEL's, then everything is fine again! Even does it when I'm using cruise control. Car just rolled 110,000 miles

I have a 2004 VW jetta GLI 1.8 turbo and when i get it to about three and a half grand it feels like my turbo is giving out, all acceleration stops. But I doesn't do it all the time, meaning not every time i step on the gas, like I can step on it all through first and second, and it will do it in third or visa-versa. Which leads me to believe that it could be a fuel delivery problem but I don't know, im new to the VW game. The check engine light will come on while the car is bogging down but as soon as the rpms go down it will turn off.

Under heavy acceleration my car surges. I have already put a new stock diverter valve on and no change....I am thinking n75 is next on my shotgun list?

Here is what happened: I was accelerating one colder morning while driving to work when the power just dropped. Then engine continued to run, but I had no power or acceleration over 3000 rpm. Since that time, that is how the car drives. It starts, runs, etc... but has no power (like rev limiter or something) over 3000 rpm. The turbo spools up fine. I do know my 02 sensors are old. The engine has 184k on it... not bad. Is this a head gasket situation?

Under acceleration between 65-80 on the highway I get a serious vibration in my steering wheel. I can feel it in the floor of the car too. When I let off the throttle it goes away. I have new tires, wheels, and new axles too. I thought it was the inner cv's but i was wrong. I was thinking possibly motor mounts, but I am not 100% sure. Specs 2004 Jetta GLI, ecs 10mm spacers in the front, coilovers dropped 2 inches, otherwise everything else is stock in the bushing mount department.

Did some searching on this and some said it could be the throw out bearing, some sort of intake rod or something like that, or possibly a heat shield..
Figured I'd ask to see if there has been more of a solution as the threads seemed pretty old.
When I accelerate or rev, the car has a rattling sound coming from the passenger side. If i take the car out of gear and slow down or let it idle, the noise disappears completely.

Middle of May, I went to Boston. On the way there, I started to notice a slight whirring noise that was only present when I gently feathered the gas to maintain highway speed. If I were to apply any more throttle, the noise would go away, and if I were to pull my foot away and allow engine braking, it would also disappear.
So I did my best to finish the trip to and from Boston adjusting my driving to avoid the noise. Once I came home, I researched and thought the noise might have been my wheel bearings (I had just replaced lower control arms, lower ball joints, inner and outer tie rods prior to leaving for Boston). I also had a shop install my upper strut mount bearings and bushings simultaneously with the wheel bearings.
Since then, the problem still continues. It has grown louder, but still occurs under the same situations. I've focused more on it and here are the conditions under which it occurs:
1. Car must be warmed up. Starting it up cold and allowing SAI to run then driving, car is fine, no sounds. Usually takes 20-25 mins of driving to get it to start making noise.
2. Car still only makes the noise when the gas is being feathered (ie barely pressing it enough to give it any sort of throttle. It does also make the noise between shifts when reengaging the gear and applying gas, as the throttle pedal passes the point of throttle off to throttle on.
3. I'm hearing more noise now during engine braking than I had been previously. Could be related?

Recently bought a black 20th for my girlfriend for Christmas. Any ways, so I floored it from a dig, and the ASR light kept coming on during acceleration and shutting off between shifts, just wondering what the situation is.

My 20th Ann. Is jerking under acceleration. When I hit the gas pedal slightly hard it starts jerking. Every once in a while the CEL will flash on and off. I changed the spark plugs and coil packs, cleaned the MAF, and now I have no real direction where to go. Maybe it could be a vaccum problem...

Ive been having two issues with my GLI lately, last week while driving on the parkway my car just randomly lost acceleration, no lights came on but the gas peddle was unresponsive. I was able to restart it while coasting and thought nothing of it. Then it kept doing it. It was raining that night but ive never had an issue before. Other times it dies it is sunny out. The second issue is sometimes when I hit over 10lbs of boost the car will start to misfire and run like crap. No CEL's come on the dash but if we scan it with VAGCOM it says theres misfires happening, obviously. Already did a smoke test and there are no vacuum leaks.

Trying to get my car all fixed up for winter, but my steering wheel has a vibration.
When on the highway, it gets worse/faster with accel. and when i let off the gas and coast, it almost goes away... does not change (better or worse) with braking.
Specs - Dropped on koni coils, 2 diff sets of rims (one brand new, one came with car same problem with both sets), spacers all around, everything else stock...
