Audi Repair: Audi A4 2002 CEL flashing and car shaking, audi a4, flashing

Question
Hi - My Audi A4 1.8T 2002 car started shaking and the Check Engine Light started flashing this morning.  I was about a 1/2 mile from my house so I turned around and drove home.  Do you have any idea what the problem might be?  Thanks.

Answer
hello
O yea, bad ignition coil. I have seen many of them .
To find out which one is bad, star the car and pull each coil out (one at the time) on good one you will see and feel difference, when you get to the bad one nothing will change
good luck             pltech
