Sorry to bother you. My daughter came home last night with all the symptoms of the ignition coil problem on our 05 A4 1.8. You mentioned it was easy to replace the coils. Could I ask for the quick repair instructions? I'm inclined to replace all 4 so as not to have to deal with this again for a while.

I am going to answer my own question for anyone wanting to know how to change the ignition coil. It is very easy. These instructions apply to my 05 Audi A4. Just remove the plastic engine cover by turning the three screws a quarter turn. The cover lifts off exposing the engine. You will see the wiring for the 4 cylinders. Press back on the metal tab which will release the wire from the ignition coil itself. That is the ignition coil that you're looking at. Then simply lift the ignition coil out of the cylinder where it attaches to the spark plug. It is not screwed in, so simply lift it straight out. Insert a new ignition coil - I bought some for $30 each. Reattach the wire to the new ignition coil. Replace the plastic engine cover, and you're done! Now, the problem I had was that one of the coils had actually broken off, so that the bottom half was still attached to the spark plug after I removed the top. In that case, I used a long needle nosed pliers to reach in and remove the part still attached to the spark plug. Easy enough. At the auto parts store, I also purchased an Actron CP 9125 code scanner which told me that cylinders 3 and 4 were malfunctioning. (Cylinder 1 is closest to the front of the car). The scanners can be purchased for about $60 at Amazon. The parts store soaked me for $90 but I needed it right away. Good luck - it's really easy, try it!

after market coils?

I own an 02 audi a4, and I'm constantly having problems with the ignition coils..now the car is no longer covered under warranty so i need a solution...I removed the cover from my engine and notice that the last mechanic that worked on my car put in an STI ignition coil in cylinder 1. The other three cylinders have stock coils in them..
Does anyone know if replacing all of the stock coils with after market coils will put an end to the constant replacement of them...or atleast make them last longer...?

Doesn't looked like they have fixed the problem yet either. I have 2008 A4 2.0T that lost the number 2 and 3 coil at about 10,000 miles. I was on the road for about 2 hours, stopped for maybe half an hour, started the car up and to my surprise the engine was running very rough at idle with a check engine light on. Gave the engine a little gas (about 2,000 rpm) and when it dropped back to idle the engine was running fine again but the check engine light remained on. Drove it about 550 miles down the interstate at 70-90 mph mph and around town over the weekend (check engine light went away within 10 minutes of the idle returning to normal) waiting for the dealership to open up the following week with no notable power loss.

Hello Folks,
The Break down:
My Audi A4 1.8T 2004 started shaking and slowed down my way back from work.
I pulled over and called Audi Dealership they told me to tow the car to service center right away and not to try to drive it further.
Diagnostic:
As expected one of the 4 ignition coils was misfiring (I could also smell gasoline from my car's exhaust). I had extended warranty on my Audi so the diagnostic/labor/repair was covered and i only had to pay some deductible. I did that but i had read online in different forums that if one coil goes out other will follow within a month and I also got similar feedback from service manager at Audi dealership.
Repair and expenses
So i paid for 1/2 hour extra labor and for rest of the coil from my pocket as warranty would only for cost associated with the replacement of bad one.
All in all it cost me around $240 (Includes 3 addition coils($36 a piece), 1/2 hour labor and extended warranty deductible)
Thanks for reading, hope it helps.

Seems like VW and Audi still has a design defect if these coils are going bad in other year models and before 100,000 miles. Generally speaking for all car manufacturers, there is an individual coil for each cylinder mounted directly on top of the spark plug. This design completely eliminates the high tension spark plug wires for even better reliability. Most of these systems are designed to last over 100,000 miles, which cuts down on maintenance costs. I have an '04 A4 Quattro 1.8L Turbo and one of my coils shorted out and my car sputtered and check engine light flashed just like everyone else is saying. This happened at 62,000. The labor was covered under warranty to replace all of them, but I had to pay for the parts which was around $36 each coil. Including the towing, it was a $357 total...this after I had just had it in for 60k service last week. I think it is a good idea for car owners to chat and compare - so thanks to anyone who takes the time to do this. This might be the only way we can keep the manufacturers in check.

Good news: Audi recall on ignition coil

First off--thanks to everyone who posted their experiences here. It's been helpful in understanding my situation with 2005 A4 1.8T. In my continued research I discovered that Audi has announced a voluntary recall of some 2001-2007 Audis for ignition coil issues. The great news for many of you is that you may be able to recoup the money you've spent on replacing coils if your vehicle is one of the affected models!  Here are all the details: http://www.audiusa.com/us/brand/en/owners/main/recalls_campaigns/ignition_coil/a- ffected_vehicles.html#source=http://www.audiusa.com/us/brand/en/owners/main/reca- lls_campaigns/ignition_coil.html&container=page

Coils

Hey, I've been in the other forum for Maint and Repairs. Just saw this thread here. My 4th coil pack in ten months failed yesterday; took my Audi in today (A4 2005 1.8 Quattro). Yes, I was told there is a recall pending for my Audi. And they have an "exception" to do the fix in advance if people come in w/ failed coils. So, allegedly, they replaced all my suspect coils under the original warranty, long since expired. Nothing out of pocket. Woo Hoo! (As a rule of thumb, if a certain car part gets its own discussion thread on Edmunds, they should probably issue a recall.)
