ICM : 93.25 Shipped: ICM LINK
Ignition Coil: 51.89 Shipped: Coil Pack Link
Use coupon code audi06
If you get the codes read, and you find a misfire on a particular cylinder, then swap around the Coil packs, if the problem moves, you have a coil pack issue.
If you have mulitpe cylinder misfires, buy the ICM

Damn, I wish I would have read this two days ago. ICM went bad (did the test as above), and I bought that same one for $130. I thought I was getting a deal over the dealership, who wanted $373 for a Bosch.
It seems to be that coil packs and ingnition control modules go bad all the time on the 1.8T. I've already done 2 coil packs on my wife's 2002 Jetta. You get used to the feeling when a cylinder drops out.

RE: HELP: big engine problem
man i dont know how many times i have to say this on the forum, but i would wish that people would catch on and inform people of the situation instead of just plain telling them not to drive there car when a flashing CEL occurs, through my experince telling someone something informative to as something bad happening in there car is much more effective than just plain telling them something bad is going on jeez..... so annoying, anyhow back on topic here, a flashing CEL occurs because the obd system is physically seeing a misfire situation and is realizing that unburned fuel is being dumped into the catalytic converter and is CAUSING catalyst damage. now what you really need to realize is there is only one way the computer can really know for sure a misfire is occuring and trigger the CEL to flash, which is when it gets no EMF (electronic magnetic feedback) from the coil to tell the computer it just fired the spark plug, therefore you have a coil pack that has taken a phat dump on you. now it would be much to your benefit to rent a scanner from autozone for like the peanuts it costs and it will tell you which cylinder it is seeing the misfire on, replace that coil pack and be happy you didnt pay the diagnostic guy at audi an hours pay for 5 minutes of work.

You have a 99, which means if it's the problem I'm thinking of, it's the ICM. Same thing happened to me.
Once you turn the car off and on again, it drives fine...sounds like an STi with an exhaust leak, and the CEL flashes, but I drove mine 7 miles to the mechanic, and she still goes...
The factory ICM is like 300$; you can find them for significantly less, though.
