      checked to make sure there are zero leaks anywhere? id do the soapy water test on the intake side. never know, might be just enough of a crack to open under peak boost, high load?

      also, like others have said, change the coil packs or move em around. I had 2 go bad on me so far and it was random as hell, but always under load and higher RPMs... idled and cruised fine.

      Checked for leaks, everything is tight. The only possible excessive/loss of air is a long shot: I'm running the VW Racing intake, which leaves the axillary air hose separate. I plugged in a breather filter for it, but it likely breathes better than VW planned for since it's not sucking though the air box. I didn't post this earlier because I thought we were past the coil pack thing, but the misfires have been on all four cylinders for a few weeks now. They seem to happen most often starting at 6500 rpm, under load, at 60mph. My engine was assembled in March 2012, I bought it in May 2012, started having issues June 2012. Is there a more recent coil pack revision than March/May 2012?

      It's only active during cold start, and then it shuts off.

      You are starting to assume, incorrectly I may add, as to what your problem is and coming up with illogical conclusions.

      Some clarification please. First, you said you took it to the dealer and nothing was discovered. That is strange because the dealer would have discovered the misfires immediately. Did you clear the codes? If the dealer finds fault codes then they have somewhere to start with.

      I think it could be the actual wiring harness for the coilpacks. Take it to a reputable VW dealer because they will find the issue, especially with misfires.

      Yes the codes were cleared before I took it to the dealership, I was there because they installed my TSW Nuerburgrings without the hubcentric rings. I didn't want them messing with the engine set-up as it would invalidate the data logs. I just asked them to run a test of ignition and fueling systems. I have no way of knowing what they actually did. Every time I have to make those log runs I have to break the law which is something I'm not comfortable with. APR wanted them run, but would not pay for a dyno to do it safely so we took that car out to an area where the Police had previously suggested to my tuner, but that's not a guarantee that we wouldn't get pulled over.

      Maybe you've never paid attention to your tach; I hit 6500 rpm at 60mph; below the speed limit. We have a few on-ramps around here on which you go from a 25mph zone to a 70mph Interstate full of trucks up a hill: very easy to hit 6500 in first or second. 6500 in third or fourth however, would be speeding.

      If you're confused about Laguna Seca, Willow Springs, and the Nuerburgring I suggest that you do a little more research: They are not public roads, and rules of the track are rather strict. Even on open track days at Nuerburgring (www.nuerburgring.de) racing is strictly prohibited, however there is no speed limit and passing is allowed so long as it is on the left. Willow Springs has similar rules, and my time on Laguna Seca was part of the Cherries Jubilee car show and we were escorted by the California Highway Patrol.

      I commend you on yet another great job of derailing my thread and bumping it without actually contributing anything worth reading; punishing those poor soles who read the top threads looking to learn something.

How far will it go at light load without misfiring?
      +1. 13k not a problem. the day my K04 was install, misfire #3. replaced all my coil packs same day. never a problem again.

      but since he "knows" its not a coilpack..................

      FYI OP.... a bad coilpack can be fine under 4000rpm.. it has no load.. how bout you listen to people in the thread that know a bit more than you about all this.

      lol. true.

      on OP's favor: he never asked a question (on post 1) asking for help. therefore its understandable that he doesnt takes the advice that everyone is giving.

      So much misinformation by the OP.....waaaaayyyyy too much.

      Change your coilpacks

      Have you been running all your logs in 1-2nd gear to avoid "speeding"?
      you really need to do them in 4th. consult your auto class texts books for why, since you wont listen to any of us.

      You have done the best job of anyone derailing this thread, since it never really had a point to start with.
      i mean you did a pretty good e-hand job to the shop that bolted the parts on your car, and bashed APR a little implying they released a product with a flaw since your all encompassing research "might" indicate a ecu hardware difference for the gli. the rest is just a sad,sad, blur of stupid.
      Dude for the love of all that's holy, Please man up and buy the coils and move on.
      just let us know its fixed so we can ride the "i told you so" express around like a broom stick pony.

      for all the golfmk6 forum guys replying to this thread:
      The B7 A4 is K03
      cause this thread is headed there too.

      Joey took great care to make sure everything was right. We ran the car a few times and noticed some misfires. After agreeing to take it easy on the car I took it home for the weekend where I experienced more misfires, all the way to the point of disabled cylinders.

      It was suggested that the plugs be regapped; still problems.
      .
      Why did you take the car when issues were clearly found.
      You should let the shop handle troubleshooting the issue.

      No one in their right mind would take delivery of a car that has issues After mods were installed.
      It's up to the shop to diagnose. If they find faulty parts, they can bill you.

      In short:
      Flashed the car back to stock. NO MISFIRES, ran under load up to 7k W/O misfires.
      With software I had to roll into full throttle to avoid EPC and misfires. W/O I can now go straight to full without issues!

      Took the car to the dealership, ran complete diagnosis of ignition and fuel systems: nothing wrong.

      So to summarize: W/ Software = problems. W/O software = no problems. Are there any more questions about my MAR2012 coil packs?

      I'm looking for solutions, so please, if you do not have a 2012 GLI or 2011 CC (have had the same issues) with the APR Stage III K04 kit please resign to spectating and reduce the nonsense on the forum.

      This guy can't even grasp the diff electrical loads based on different tunes.. The stock tune doesnt stress the coilpacks.. Don't replace those coil packs.. Just delete this idiots thread instead.

      No questions, just a statement:
      Dude!, At least one of your coil packs is bad.
      Listen very carefully.......................
      NOTHING you have said or done even remotely points to a software problem. your car has a hardware issue. if you insist on trying to get the dealership of all places to to fix it for you, stop clearing the freaking codes showing the misfires and give them something to work with. Stop posting your lunatic "thoughts" about the software not working, that's not the problem.
      Like multiple people have told you over and over here, swap the coil pack from the misfiring cylinder to another location on the motor. use VCDS and watch the misfire move to the new cylinder. Whoa "magic". buy new coil pack and finally enjoy the car you should have picked up not the one you've been complaining about for over a month.

      the solution for you seems to be quite clear. trade the gli in on a GTI, cause when we have your problem, a coil pack fixes our issues. plus there wont be any of your "hardware" compatibility issues with the ECU and the software.

      The misfires were on all four cylinders with software. My early posts were as the problems were discovered. The only times I pushed it after that point were while running data logs for APR, during which all four cylinders had problems. No misfires happen without the software. There were no codes to clear because none were thrown after reverting back to stock software. The engine can freely rev well above the point where it would shut down when running software.

      Doesn't matter. I'm telling you that if you replace all four coil packs your problem will be solved. You have been dealing with this issue for a long time. If I was you I would have lost my mind waiting all this time for some to fix a problem that you already know the solution for. I installed a K04, the next thing you know I'm having misfires. Replaced all for packs problem solved. Before I replaced them I had the EXACT and I repeat the EXACT same symptoms as you. In stock mode no misfires. Only under load would I have a problem. The dealer told me the coils were fine but they were not.

      Just so everyone that stumbles into this thread understands exactly how stubborn the OP is, here is a quoted exchange from the APR Ko4 or AWE Ko4 thread. I don't know how APR (or any company) can put up with this kind of ignorance.

I have had ZERO suggestions, ideas, or even apologies for wasting my time from them. I know some people swear by APR, but for me it's been mostly swearing at them.

From what I understand, everything we've seen on your vehicle looked perfect, yet you're reporting misfires.

      How should we handle the situation? The limited data looks perfect, other customers with the same engine and same ecu run perfectly. We've tried adjustments in some areas to see if anything changed, and it didn't. So, like I said, what should we be doing that we haven't already, and how do you feel you've been treated poorly when all we've done is helped you out with suppor the entire time?

      We've made suggestions on what to change based on our previous experience with other vehicles. Have you tried every suggestion we've made? Have you swapped coil packs, spark plugs and injectors to see if the misfires follow to the other cylinders? These are important things you need to do when there's an issue. Publicly blaming the software before you have ANY data doesn't help anyone.

      As we've said before, it's best to check all common hardware related issues as we've sold 1,000's of K04's across many different VAG makes and models, all without issue.

      With stock software, less load is placed on different components, so the likelihood of misfires will be far less.

      Anyone is free to bring their vehicle to us for diagnosis too. If we find something wrong, we'll fix it like always.

      So overall I have tried to stay out of the stupidity running wild in this thread but alas I figured I would throw my knowledge into this. I currently DO NOT own a K04 car nor APR software on my '09 TSI so take this all for whatever you choose. But I have done a lot of research on/for my car as I have done all the garage work myself. Been through 3 exhausts, 3 intakes, 3 sets of coilovers, and 2 catch cans among a multitude of other part swaps and other upgrades. I have had on and off issues with my TSI from the first days of modifications at which time I have either forged my own roads or searched out advice from those in the 'know'.

      For the most part the guys in this thread are being helpful and only giving the OP options (mostly ignored) to test. Arin with APR has nothing but been helpful to me in the past even when I was running a competitors software to help diagnose an issue with mismatched hardware and I believe he is doing so currently with the OP. If you won't take even his advice, your option is take all the hardware off and park your car as you no have real reason to be here crying to a forum that actually wants to help you but you then continue to ignore. Yes he has sold 1,000's of K04s with very little issues but the real deal here is they have the experience of testing these way before they ever hit the market.

      My honest opinion is its hardware. You know why I am saying this? Is because I been through 3 VWs of assorted modification and every time I have got the mod bug I had been hit buy one part or another rearing it's head towards failure. Whether it be coil-packs (went through literally sets on my 1.8t, a set on my R32, and 6 on my TSI), spark-plugs (a few sets on each), injectors (one set in the 1.8t), fuel pumps (nothing yet), or any other 'wear and tear' (countless overall) item you have to know **** can break. If you believe every car has zero issues regardless of modification levels then you are kidding yourself and should start taking public transportation which still can fail from time to time.

      I'm subscribing to this thread just so I can see what happens if/when the OP replaces his coil packs.
