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.
Every time I stop fairly quickly my battery light comes on and I loose all power. Lights, power steering, everything goes... Is this a connection problem? Its not the battery since I have to turn my car off and start it again for it to be alright.. What's going on?
View 14 RepliesFor about two months I've been having a backfire problem but only when I get on it. We checked for leaks and nothing . The car had 11 codes and were all short to ground. Mechanic is saying my ecu is going out and I need a new one. Is it possible?
View 8 RepliesI was driving and went to shift from 5th to 6th and when in 6th the engine just revved freely as if it was in neutral. When I tried to get back into 5th it did the same thing. It's also very hard to get into 1st.
I want to try the alignment but I can't find one specifically for the stock 6 speed and I don't have my Bentley DVD on me.
Alright so basically i lost 1 and 2nd gear and i want to replace the transmission since this one already has 150k on it. The hard part is finding a used one because of the six speed! What models can i swap transmissions from? Like i heard i could use a 2003 Audi TT six speed transmission! What I can use to swap out my transmission or do i have to just look for a used one specifically for a 20th?
View 20 RepliesWas 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 RepliesI was driving fine, pulled into 7-11 to get some drinks and came out went in reverse to get outta the parking spot and put it in first and didn't go anywhere....
When i put it in first or second it feels like its in neutral and the car doesn't stall. 3 through 6 gears are fine.....
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.
View 19 RepliesI have 20th gti and I downshifted into third the other day and heard a small grind and all of the sudden I lost all my gears, I couldn't shift into anything and was stuck in third. I was able to move the shifter up and down from 3rd neut to fourth without engaging the clutch but it was all the same gear:S I managed to get home in third considering I was close by and when I stopped i was able to throw it into reverse but it would act like i was in a high gear(either 4th 5th or 6th I am not sure).
View 4 RepliesI am getting the following trouble codes:
P0342 cam position sensor A bank 1 Ckt Low Input
P0102 MAF or VAF A Ckt Low Input
The accessory belt moves when I try to start it, but my timing belt stays still, but is kind of tight/very little slack.
It died on the highway, was in gear and it just lost power.
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 RepliesYesterday, 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.

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?
View 9 RepliesI'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.
View 4 RepliesI 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?
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.
I recently took out my headliner And my passenger's side seat. When I put everything back together, I turned the car on and the light came on. What can be the issue?
View 10 RepliesI f I have an airbag light on in my car... How do i get it to go off. Can i vag-com it off.
View 2 RepliesSo I bought my 20th with the airbag light on... Never really bothered me till now as I'm tying to fix everything that's wrong with it. I vagcom'd it and it said driver side seat buckle was the fault. Looked under the seat and it seems the white plug isn't plugged in. I haven't taken anything apart yet to get a closer look, but could that be the problem? Does that plug actually plug into something or is it just a loose plug?
View 9 RepliesRecently I installed my NewSouthPerformance boost gauge that sits on the steering column and a couple weeks later i noticed my horn stopped working. I didnt cut any wires so i know it couldnt be that. I pulled the fuse out and put it back in, now it works but sounds like a old man with extreme lung problems. Now my Airbag light came on and how to "fix" it.
View 8 RepliesFinally decided to rain in CA today and noticed after I got to work that my EPC light had turned on. Car doesn't wanna boost and has very minimal/close to none power.
