Hi, I have a 2003 A4 3.0l mpi v6, (ASN engine) I've plugged her in to my code reader. I have codes 11684 (multiple cylinder misfire) also 1167, 11688, 11685, 17511. Has anyone else had these problems and looking for the best way forward.Thanks in advance

 

Honestly, I am not familiar with those exact codes but after 3 Audis, misfires are usually related to coil pack issues. Does it indicate a specific cylinder? If yes, try swapping coil packs with a good cylinder and if the problem follows, you got the culprit.
