      So I was driving my car tonight kinda hard (not that bad) on the highway, my Rpms were in the 3500-4000 range for a good amount of time.. After i get off the highway the car is running rough, sounds like a wrx. I know people on this site say a car sounding like a WRX is most likely the coil packs.

      My question is... What causes the coil packs to go? Is it just coincidence that they went after I was getting on the car a little? And how can I determine which coil pack out of the four is the bad one or one(s).

      Pull them all and if one is bad the metal may appear to have a brownish tint. (I have no idea why that happens but it does)

      Some of my symptoms were black smoke coming out of my exhaust!

      there is no 1 reason why the go, they just do. they are an electrical component. maybe they were designed poorly. all i know is i have a set of 4 in my trunk for just that occasion.

      and the car sounding like a WRX is a pretty good symptom that its a bad coil pack right?

      blakc smoke is a sign of it running rich. This might mean that the fuel wasn't being ignited. do you have a CEL right now?

      I do, but its been on for a little bit

      go to advanced auto or something and have the codes pulled and see what you come up with.

      Typically your engine will be running rough. You usually can head/feel it missing along with degraded performance. Your CEL light sometimes will flash indicating a misfire issue.

      The easiest way to determain which coil pack is bad is using VAG-COM.

      Without VAG-COM you can remove each coil pack and look for stress/ burn marks. If none of them show physical signs of damage, pull and read the spark plugs.

      if you dont have a VAG-COM, just a generic OBDII scanner and you get a misfire in a cylinder, swap the corresponding coil with another one and see if the CEL jumps with it.

      either way, there are a thousand reasons why you could be running lean, but relatively few places that could be the cause of it. its not getting burned, so it definitely sounds like something with the plugs or the like.

      is it bad to drive with bad coil packs? I only ask because I have other coil packs at my parents house, and I wanted to put those in and see if i fix the problem, also my friend with a vag com live up near my parents. Its about a 45 min drive. What do you say?

      dont. you will be dumping raw fuel into your cat. dont drive on it

      I pulled them and they all seemed to be alright, the only difference I seemed to notice with one of them was all the way inside on the metal that actually touches the spark plug was either black or brown, either way I couldnt see it, where was on the other 3 it was clearly visible.

      Its like that skit on Seasame street - "Which one of these is not like the others?"

      Sounds to me like you've narrowed down which one is bad.

      Haha thanks man, I really hope thats the issue, Ive had a few issues with the axles on this car and I jsut spent alot of money replacing those, then the week i get the car back this happens!

      of all the problems you could have I think coilpacks are pretty far down the list regarding expense and PITAness.

    17. 01-18-2008 03:06 PM #17
      Oh i know Im saying im grateful its the coil packs, and I hope its only those because they are cheap.

      Coil packs most often go if you are driving a 1.8T

      Seriously, I've had a number go on me, and it's normally under high acceleration. I kept replacing one here and there with the Bremi "R" revision (AWW engine), or whatever was the newest at the time. Problem was they kept poping out and going bad. Finally, when two went bad at the same time, I changed all 4 to the Hitachi "E" revision normally, AWD engine) and bolted them onto the valve cover. I haven't had an issue since then.

      I went through 7 coil packs in three years on my 2002 AWP code engine.

      I'm certain this is not a VW approved diagnostic technique, but it works. With the engine idling, pull a coil off the sparkplug. If it is good, you will hear a pop, pop, pop sound of the spark on each ignition cycle. No pop= bad coil.

      Ill give it a try, ill try anything, I tried replacing the coil that i thought was bad, but it didnt work, I have to spend more time on the car tomorrow

      that's not necessarily true in all cases. i had two of the brand new version "R" go out on me after 2 months! they looked brand new!!


      Edit:

      Please replace them all with Hitachi bolt-down coilpacks found on http://www.ecstuning.com and save whatever good coils you have in your trunk
