Engine temperature too low. Turbo boost pressure too high. The car has the APR 93 octane program, carbonio intake, and silicone TIP.
What could be causing these codes? The car gets up to temp (190) real quick and stays there, and I don't feel a fluctuation of boost.
When I hit the gas and my turbo reached high boost (15 psi and up), it would slightly sputter and make an odd sound. I even noticed my exhaust made a different exhaust note than usual. While it sputtered the CEL began flashing. I then drove it normally (not high boost) all the way home and it drove completely fine. I'm gonna try and get my codes checked tomorrow.
View 9 RepliesThere 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..
So my 20th runs completely fine until rain is involved.. Once it rains and I bring my rpms high or use my turbo it almost staples out and the gas doesn't work.. Also I notice it shoots out a puff of white smoke and my. Turbo doesn't spool at the way.. It basically tries and just does something like psh psh psh psh like second spools? Could water get in my. Turbo or something.
View 19 RepliesSo I just installed a boost gauge. Vacuum line is running off the fuel pressure regulator. My boost is now not going over 10 psi and the engine is cutting out. It kinda feels like the dv isn't holding psi but just always open. The car is a 05 gli with intake and exhaust.
Also the car seems to be running alright at below 2000 rpm and it just starts to cut out when it should be making boost. And I'm pretty sure this car is reprogrammed because yesterday when I finished the boost gauge install it was running at19 psi.
I know it has to do with the thermostat and coolant sensor but I am trying to hold off on doing it till the winter cause my car is at 68k so i will be doing the timing belt. It would be easier to install them all at once. is it bad to keep driving the car with this problem?
View 9 RepliesI just replaced the turbo to manifold gasket and bolts but the but bolt closest to the engine keeps backing out.. i cnt seem to find a tool that can tighten all the way..
View 5 RepliesI am trying to swap my ecu for a chipped one out of an 04 gti 1.8. Both awp engine codes. I programmed the immobilized and the car doesn't start. I am thinking it has the ignition kill feature but the guy who sold it to me doesn't think it does. i was just wondering if the ecu's are compatible even though the part number is different.
View 8 RepliesI have a 2003 20th ann. GTI, it shut off on me on my way to work. It would turn on but only for a sec and turn back off. I turned it on and tried to move it over out the way of traffic and wouldnt move and turn back off. Got the check engine light checked and the codes P1007 which is coolant temp sensor and P0011 which is camshaft sensor. I replaced both and problem not solved car will start but wont go and turns back off, black smoke and a strong smell of gas comes out the exhaust.
View 3 RepliesI have multiple O2 codes on my '02 gti. It is giving me a check engine lights as well as the traction control light on. I received 6 codes all but one of them had to do with the O2 sensor and a short except for one that came in as the MAF. Both O2 sensors have been replaced and the codes still won't clear. I bought it in this condition, it runs really well so i wasn't to concerned about it, but the lights are starting to get annoying.
View 2 RepliesCar started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.
Alright i have a 05 1.8t GLI I just installed a 42 draft designs full 3inch turboback, and a eurojet turbo inlet hose, after I put the stuff on my check engine light came on which I thought was gonna happen and is normal but my traction control light came on as well, the cars running better then ever and pulling harder then ever, but when i hooked it up to the computer I'm throwing 18 codes? Ive triple check to make sure everythings tight and in the right spot? What could be wrong?
View 5 RepliesMy 20th just hit 107k and in the past couple days I have noticed that my car is somewhat sluggish compared to normal and there is also a VERY audible whine when I take off from a stop.
The same thing happened to my friend's Turbo 300zx when his turbo went out and I think that may be whats happening to mine.
This is the perfect excuse for me to replace my K03 with a more respectable turbo like a K04 hybrid or possibly a BT setup. What I'm wondering is how expensive these options are and how worth it are they. I know you can get away with not upgrading certain things when going BT, but I want to do things right to avoid problems down the road
SO....
I currently have Stage 1 APR software, DG Short shifter, and and itg SRI.
I'm not trying to build a 500hp fwd beast, but what all is considered necessary to run a BT without issues and what would the price be? Again, estimates are totally fine, I can locate parts if i know what to look for
And lastly: What is the general opinion of the ATP Eliminator? I haven't heard much about it and all of my research is fairly inconclusive. I'm just trying to weigh my options.
I'm to the point of driving the car off a cliff! I've included a log of the car acting upt. The car is a 20th AE GTI AWP. It was chipped all it's life and ran like a champ. In November I installed a Frankenturbo F21T turbo kit, Bosch EV14 550cc injectors, 3" MAF, eBay FMIC, 3" catted exhaust, and a custom tune from Motoza. Dave at Motoza has updated the file 4 times and no matter what he changes, the car will boost up to the requested boost of 19psi and hold it for almost one second, then boost will drop to 12-15psi and then boost past the request to like 22-24 psi and go back and forth until the gear is over and I shift. Then it does the same thing in the next gear. i just want a solid 18-20psi without a manual boost controller! Things I have tried:
-Changed the N75J back to a NEW stock N75
-Replaced all the N75 vacuum lines
-Wastegate cracks at 7-8psi
-Replaced every worm feed clamp to a nice T-bolt clamp
-Boost leak tested to 18psi and found no leaks
-Deleted SAI, N249, and N112
-Unplugged MAF, nothing changed

I have a 20th 1.8t. It was running fine last week but all of the sudden i was only getting about 4-5 psi. I have check all over vwvortex for somewhat of an answer. I have no C.E.L.. I have checked for vacuum leaks with nothing coming up. I tried to check for boost leaks but it comes out of the dipstick hole. I have undone and re-installed the pancake pipe. The DV is holding pressure.
View 1 RepliesHow hard it is to install a turbo manifold??
View 3 RepliesI 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.
View 1 Replieswhen the traction control is off my boost hits 18psi and there have been times where it was 20 psi. My friend said i probably have stage 1 software .
View 4 RepliesStart 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'm not sure what to make of this ... I disconnected the battery before installing . The gauge seems to be reading correct based on what i researched. If there was a slight leak would it throw the CEL ? is it maybe just a one time thing that needs to be cleared afterwards ? Car drives fine and I plan on trying to stop at autozone to get there crapo freebie scan . Kinda annoyed considering everything went smoothly up until I drove the car more then 50 miles .
View 14 RepliesSo I have a 20th AE with 113k Miles.
All of engine is stock, but when I FLOOR it from about 3rd-4th or sometimes 2nd-3rd the car will build up boost but release it without me letting go off pedal.
So, basically as I am driving the car sort of builds up, drops, builds up, drops without my doing anything but drive.
It will rev to about 3k stop for a second, rev to 4k stop for a split second, rev to 5k and so on... Not sure what this is or why it could be happening...
