      Hey hey... I did mine yesterday. I bought a new coilpack plug and a section of wire with the spade plug that goes into the coil plug for $15 from the dealership. I got an extra one with the spade and wire attached. I can take that, put a butt connector on it, heatshrink it, and put a ring terminal on it and heatshrink it for you so you can do what I did. Just send me $20 an I'll send you the wire the same length as I did mine. BTW the wire is 12 gauge.

      Hmmm if I go to the dealership what do I ask for, or do you have a part number or pic of this concoction? I don't know if sending a stranger $20 is the best idea.
      thanks

      I threw the receipt out, but what I did was go up to the parts counter. I asked them to pull up the diagram of the coil pack. I said i needed to get the 12 gauge wire with a new spade to replace a ground in it. He went out back, came back with a couple different wires, what you want is the medium sized one in the computer. Its a yellow wire with a spade end (the one that goes into the coil plug. I bought two of them. Then I bought some 12 gauge wire at advanced auto. A package of weatherproof heatshrinkable butt connectors and ring terminals. You pull the coil plug off... look inside, push the purple piece out of the plug. Then you push the spade out with a small flathead screwdriver or you can pull the wire carefully. You crimp and heatshrink the wire with spade to the spoiler of wire. Run the wire through the wire loom to under the battery box. Cut the excess wire. Then you crimp and heatshrink a ring terminal on the end, loosen one of the grounds, install the new ring terminal and tighten the ground back up. Put the purple part back into the coil plug and reconnect the coil pack. Oh forgot to include removing the battery/battery box part in there. But thats pretty much it. CEL free and the car sees to have a tiny bit more acceleration.

      Thanks guys gonna try this tomorrow. I've been fighting this problem for a while....after changing the spark plugs wires and coil...the problem still seems to come and go. I was actually starting to think it might have been a fuel issue. Hopefully tomorrow the problem will be fixed!!!

      haha so easy... you could simply cut the brown wire, butt connector it to a 12 gauge peice of wire, and run it to the grounds under the battery box... simple as hell. I just went and did it to spec...

      Thats the harness. You pull the top cover of it off, find the brown 12 gauge wire, and proceed as stated above.

      I see that little clip opens up on that connector, thanks will do this tomorrow. Too bad there wasn't a way to remove entire wire out of the inside, or is there? I will just cut and butt connect it. Kinda odd to run it straight to the battery, not sure where that brown wire really goes inside that plastic covering all the wires, oh well.

      I told you there is a way to take it out. The purple piece on the inside of the plug sides out the side. then you pull the brown wire. That why I offered to sell you the wire with the connector that slides in place of the brown wire. And the wire doesn't go to the battery, it goes under the battery box, you remove the battery and the four 10mm bolts that hold the box down. You will see a couple nuts holding some wires down. You put the wire from the coilpack on one of these. make sure you do it right, with heatshrink butt connectors and heat shrink ring terminal.

      Yes, I know it goes under the battery tray. Wish I knew what this wire with the slider connector was. I will see, maybe the hardware store sells something the same otherwise butt connector.
      thanks

      One last question, what do you do after the brown wire is out? Can you pull it from where it goes or it just sits there not connected to the harness?

      Mine is just sitting there not connected to anything. If you want to waste the time pulling it out of the loom go right ahead.

      Any way you can send me a pic of what I would be getting? I got the plastic shell off the harness, found the wire and there is not a lot of room to work with. Your idea seems more permanent and better. I don't want to screw up something.

      I would be sending, The vw 12 gauge wire from the dealership with the spade connector that slides right into the plug, probably like 3 feet of 12 gauge wire crimped and heat shrinked to it, and a ring terminal end that you can crimp/heatshrink on your own when you determine how much of the wire you need to use so you don't have a ton of extra wire in there. Its up to you if you want it, I could put it all together quickly enough.

      Let me see if my dealership has one these spade connectors you are talking about, and then I will see if I can put it together or have you send it all I guess.

      They don't just sell the connector, it comes with a short length of wire.

      wire 1 and wire 6 are the largest and both the same size. I'll take a look and tell you which number to cut

      The purple piece pops out easy I hope or does it slide out the side like on the TSB for the 1.8s?

      Better yet, does the connector and wire have a part number on it somewhere. I get vw parts discount through my dad. I will go on my lunch and see if they can pull it up.
      thanks

      Thats a crap ton of wires, that'll cost you a fortune to buy the whole harness and is not needed. You just need the one wire that goes into one of the slots. the one that goes into #1... all you have to do is push the purple slider out the side, pull on wire #1 and it comes right out... you put the new wire with the spade end on it into the slot, push the slider back, and crimp and heat shrink.
