Question about 1998 Audi A4
P0304 Code Appears.Ignition leads/bad plug in cyl4/or possibly the coil pack.???
Coil packs are relatively common failures on the B5 A4, although it's usually on the four-cylinder turbo. Swap the coil pack with another one on the bracket, clear the code, and then run the car and scan for codes. If the code doesn't change, then the problem is plug or wire. If it follows to a new cylinder driven by the same coil that is currently failing at cylinder four, then it's the coil pack.
