Is there any physical way to tell if a coil pack is bad? I pulled a code today for a misfire in cyl 4, and I'm guessing it's the coil pack, but I'd like to be able to tell before I buy a new set. I've had the car for well over 20k and haven't changed them once since I bought it. I guess I could swap it out for one of my other cyls and see if it reads a misfire in the new cyl, but is there any way to tell that requires less work? [>_<]

Btw, don't throw shit at me for asking this, but which is cyl 4? The one near the rad or the one near the firewall?

On a side note, it my fuel pump was on it's way out (which I believe it is) it would cause a misfire in more than one cylinder, correct?

Fuel pumps dont start going out, they are either working or dead.


#4 cylinder is the one near the firewall.


If you want to find out if it is the coil pack, just swap it with the coil at cylinder #1. If the misfire jumps to #1 its the coil pack, if it doesn't then it could be a bad spark plug or even bad compression.

it is most likely the plug if you havent changed them in 20k.... and swap the coilpacks around and then re-read the code and see i it changed.. it could be a bad icm..

off topic---has anyone ever tried to repair a blown icm..

The plugs were changed less than 3k ago, it's the coilpacks I havent changed for over 20k. I'll swap em around after classes today...

So I gave VW a call out of curiosity. $41 for the same exact part number. Go figure. Slapped it in and shes running fine, taking the comp out to clear the CEL. Thanks again dudes.

I had the same CEL problem, coilpacks were new and the plugs were new also. It turns up that the injectors were somewhat clogged and needed some fuel cleaner($13.99 Chevron treatment).[up]

Your car should have a recall on coil packs. Call an Audi dealer, and ask them if your VIN has a recall. They should replace all of your ignition coils for free. All 2001s have it.

Go to an Audi dealer to check for a recall on your car. You can't return the coil as anything electric cannot be returned to the dealer.

Sorry to bring back an old thread, but I can't find anything about that recall. I just called Audi and NHTSA...

I would love for it to be true as both you and the guy sitting next to me are swearing there was a coil pack recall but Audi and the Government are swearing otherwise. o.O
