There are part selling sponsors on this site. See if they have any NON Chinese coils.
My parts come either from the dealer or a wholesale supplier that does not sell to public.

 

i would call up the dealership, ask them what brand name they sell, and also ask them what the part number is. then jump on ebay and order it. i just picked up one from ebay name brand ( WELLS ). It is working but im still trouble shooting missfire myself... i found this other thread on here stating it could cause additional problems if not fixed soon, or it may have already caused problems, i copied and will paste it, hope it helps......




I learned a lot in the last week dealing with my car issues. The first item I forgot to mention is that I also replaced my Ignition Control Module...

I spent hours researching all the articles on this forum but I tried everything with no result. After a very expensive week, I asked my mechanic why

this happened? He broke it down in a very simple way for me to understand and I want to share it to anyone else who might be dealing with this same

issue so you do not end up spending as much as I did!

With this process my mechanic used the computer only to Identify what we already knew which that the number 2 cylinder was misfiring. We came to that

conclusion before by unhooking each coil at a time while the car was running until it did not make a difference... Obviously number 2...

1st: My worn coils caused all of this damage! The resistance of a worn coil will can cause the entire system to heat up creating major damage. As a

coil begins to degrade, it will miss fire under high use and chances are you will not notice it when you are driving the car under power! That is why

we love Audi...

2nd: As this misfire continues to occur it will begin to heat up the Ignition Control Module. The ICM can take the heat for a good amount of time

because it is air cooled with a heat sink through the air box. This will pass the resistance into the ECU which is not a good thing. The ECU in the

early years of AUDI are not built to take a lot of heat and they will fail with this extra resistance!

3rd: When the ECU has taken to much the system fails! This will cost you a lot of time and a bit of money in the end.... The hardest time I had was

locating a ECU without spending 3 hours of phone calls or sending it out for repair! I ended up removing the shrink wrap off of every wire in the

entire ignition system to locate the path of wires. I noticed on the number 2 cylinder (in regard to the excess resistance) had fried the number 1

pin port wire all the way to the ICM... (pulse fire wire) Obviously the resistance was very serious and caused a lot of damage to the single wire

connecting the number 2 cylinder to the ICM. Now that all the wires were open I replaced the single wire but it required a ton of work to do so!

About 3 hours of work for a single wire!

4th: After all the work was completed, I hooked up the battery, cleared the codes and she runs 100% better than she ever has since I first got her.

Her name is Ruby and I am damn glad I did not see her towed on the back of a flat bed!!!!!

Conclusion: Now that I have spent the time and money to solve this issue, change those coils more often than you would think! It will save you a lot

of time, patients, and money in the end. My A4 runs smoother than I have ever driven her. Blown away at the increase in quality and I have owned this

car for a very long time.....

Hope this helps.....

 

There is really 2 brands, beru and hitachi. The hitachi bolt downs seem to last a long tine without issues

 

I purchased my coils from germanautoparts.com and they were $31.99 each (Beru/Hitachi).

 

I just ordered some parts from AudiUSAParts.com. Best price I've been able to find (without it being eBay) and it's through an actual porsche/audi dealer in Oregon. Coils on there are around the $16 range plus they have car diagrams for easy reference.
