GTI 337/20th Anniversary :: Car Going Into Limp Mode Or Just Not Boost At All
Having trouble with car going into limp mode or just not boosting at all. Tried some basic things to fix it, plugs, coilpacks, tune, none have work.

Was driving the other day and one of the couplers came loos and I lost boost and went into limp mode. I pulled over, got it reattached, and after that it would only hit 10 lbs. i have a KO4-001 with the GIAC file and it usually hits 20+ and holds 20 lbs. I have a regular code reader and I had a code for the EBC, cleared it, rechecked the hoses, and verified with the flash loader that I was on the correct file, but it is still only hitting 10 lbs. What else I should check.
View 1 RepliesGTI 337/20th Anniversary :: Over Boost Codes / Limp Mode
There ended up being 6 or 7 codes. Originally the first O2 sensor and wire seemed to go bad, I replaced them and it ran well for a couple days and then started running like ass again...Now there are a few codes, none for the 02 sensor, but for over boost issues...Does this mean my n75J valve is causing the problems? Is it possible that my software is just going bad? ...I bought the car somewhat molested and don't quite know the extent of the parts on it, nor the brands( specifically, the software...).
The current codes being thrown:
P0238 mani pres g31 sig to high
P0234 overboost
P0106mani barometric sensor g31
We replaced the manifold pressure sensor, and am not having the issues but they could and probably will come back after 50 or so miles...Previous code also was P1114 02 sensors and we replaced the front sensor. It may be that the software that is on the car is starting to go..
GTI 337/20th Anniversary :: Turbo Going In And Out Of Limp Mode - MAP Sensor Bad?
So I have a bad map sensor and lately my turbos been going in and out of limp mode. I recently just replaced with a new n75 valve and it solved the problem for about a week and now it's acting up again. Its not a constant problem it occurs usually every 20 starts. Could the map sensor be the reason why my car is going into limp mode?

Preliminary info:
APR 93 tune
Carbonio Intake
Silicone TIP
I picked up my 20th today and drove it 4 hours home. It has 74k on it, original timing belt. The timing belt kit is in the mail on its way here. Its the first thing I'm doing.
As I was driving it home on the autobahn doing about 150k/hr and I gave it half throttle to pass, I felt the turbo spool and I accelerated past the car. However, when I went to make the next pass, it felt like I had no power. I feathered the throttle a bit and it felt like my car was only getting maybe 3 PSI of boost. Very little actually. I do not have a boost gauge so I can't really say it accurately. As I was driving, i shut the ignition off and turned it back on. After that, I was able to get full pressure back.
GTI 337/20th Anniversary :: Limp Mode Coming Back On After Few Times Of Driving
I got a quick question about limp mode. I know this has prolly been covered a few times but I couldn't find anything too similar. Well, to start out my car cannot boost past 3lbs. If i turn the car off and take the terminals off the battery and let it reset for a while, it goes back to normal for a while. After a few times driving it, limp mode comes back on.
The first time this happened, the check engine light came on also. But once I reset the battery it turned off and went back to normal. But it never stays away for good, limp mode always ends up coming back...
GTI 337/20th Anniversary :: Popping Noise Come From Passenger Side
I recently developed a tapping/popping noise come from the passenger's side of my GLI. The noise is kind of hard to explain, it's similar to the popping sound the seats make every once in awhile when you move around in them, if that makes any sense. I can't really get a video of the sound because I don't think it's quite loud enough. It's starting to get worse, and getting aggravating. It's not coming from the seat, it's more up near the front of the car, maybe where the door hinges are? I can't really pinpoint it.

sometimes when i switch from 1st to 2nd or 2nd to 3rd i get a loud popping noise like my exhaust is hitting the under side of the center column. I have had the car on a lift and shook the hell out of the exhaust...it's not moving enough to cause that loud popping...so i figured it could possibly be the dogbone mount gone and the downpipe is hitting when i shift because the mount is bad?
Or could it be one of the other mounts...I'm going through a divorce right now and really really broke so i need to make sure i get the right one and fix it right the first time. What mount it is if not positive its the dogbone?
GTI 337/20th Anniversary :: Boost Drop After Popping Noise When Driving
Was driving when I heard a pop n my boost dropped. Normally run 17 psi but my boost gauge is now only reading it's pushing 4psi. There is no smoke coming out my exhaust or anything, when I had it scanned it read it was a bad pressure sensor in the inter cooler so I replaced the sensor cleared the code took it for a drive n the same thing happened...check engine light came back on n still running like crap.

I have been battling a big boost upon acceleration at stoplights for approximately 6 months. Now twice I have gone into limp mode and the tech reads: PO700 (Transmission) and PO731 (Gear 1). I just turned over 190,000 miles but only purchased it a year ago. What is the problem(s)?

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 :: Inter Cooler Pipe Keeps Popping Off?

GTI 337/20th Anniversary :: GLI Pulsing During Acceleration
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.

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
GTI 337/20th Anniversary :: Stutter During Acceleration On Highway
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?
GTI 337/20th Anniversary :: Turbo Is Going Out / All Acceleration Stops
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.

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.
