Hey guys, I had a serious problem with my Audi today on the way to work. Last night on the way home, the check engine light came on. I figured I would check it out today as it was well past 6 and no local service shops would be open.

So this morning on the way to work, the engine light starts flashing and I seriously lose power (and fuel economy). This was while I was on the freeway, about 10 miles from home, so I kept on to work. When I finally got there, I noticed a very rough idle and a burning smell. After doing some digging it appears this is an ignition coil issue.

My question is, is this something I can repair myself? If not, is it a costly repair?

Please let me know, this is fairly urgent.

Thanks!

 

Coils on the 1.8t are easy to replace. Search this forum you'll find tons of info. Coils are about 30-40 dollars each oem at the dealership. All you need to replace them is:
a flat head screw driver to pull the connectors off (put the flat head screw driver at 45 degree angle between the connector and the coil and when you hear a click remove the screw driver and pull on the connector)
Another bigger flat head screw driver to carefully pry off the coils and I also believe ou need a little hex or allen wrench to remove any screws that hold up the coil wires.

 

I just replaced all 4 of my coils on my A4 and it was the first type of service I had ever done myself on a car. I bought the coils off ECS tuning and it was around $120 for all 4, and it took me around 15 minutes to replace all 4. Very easy DIY job.

 

and you know what... while you are inthere.. mine as well throw some new spark plugs in there aswell. I use denzo

 

The screwdriver method of removing the connectors works but can break the clips. If you push in on the connector before you push down on the release you relieve pressure on the clip and won't break it. Cheapest place I've found to get a set of 4 rev R or E coil packs is audipartssuperstore.com, $112.21 delivered.

 

Thanks for your help guys!

 

the 03 a4 quattro 1.8t is also on recall for ignition coils so u could get them replaced for free
