I was coming back home to FL yesterday from NC. On I 95, all of a sudden my car started shaking... spent the night in georgia, next day went to Advanced Auto Parts, they did a free diagnostic computer check, and i had a Misfire cylinder, first checkd if it was the spark plug, it was good.. than checkd the ignition coil... and that was the problem... bought a new one for 37$, popped the old one out put the new one in, done. problem solved...
at first i was worried if it was something more serious, but then i thot its most likely one of cylinders are out becuase the car can still drive but it shakes and its hard....
finally home and the cars running better than ever.. easy fix.

I also have a 2005 A4 1.8T 33K miles.
My passenger window regulator went bad -- So I brought it in to have it serviced. My warranty had JUST expired a day prior, but they were nice enough to extend it to cover the repair, as well as a 35k service.
They fixed the window -- but whatever bonehead they had do the repair, forgot to re-attach the door latch so I could no longer open the door from the inside.
After the holidays, as I was about to bring the car in again -- My engine suddenly won't turn-over.
I had it towed, and was informed that the Ignition Coil #4 shorted and melted the connector. They replaced the coil and repaired the wire.
The parts were $97, but the labor was over $500 -- Due to the fact that they had to run a system diagnosis on the car, and bypass my aftermarket stereo.
I pitched a bitch and they knocked some $$ of the labor. But here's the kicker -- I get back into my car and the passenger door STILL won't open!
Unreal.

Hello,I have an 2004 A4 1.8, with 83000 miles. My check engine light came on an I think it is an engine coil that needs to be replaced. I had one replaced about 6 months ago and i was wondering if there has been a recall on these items.

Are you sure you have an ignition coil that needs to be replaced? Its a $30.00 part. And on an A4 you have four of them. You didn't indicate any signs that it is an ignition coil.
You should get your car hooked up to a computer to see what the real problem is. Depending on the error code, it may not be an ignition coil at all.

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!

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.
