2001 Audi a4 1.8t engine died crank no start (epc light)
 

Never owned an Audi till 2 days ago. Bought car used supposedly ran perfect no problems drove for about an hour parked car next day headin to work car dies outta no where. No spit and sputter just dead. Epc light came on and currently have a crank no start. Ignition coil wire harness has some exposed wires and a broken wire coming off that little black box on I believe is on top of cylinder 4 ( cylinder closest to cab). Figured ignition harness is the problem having a hard time finding a replacement online. Just trying to see what else you guys know about this. Thanks for the help.
