I had engine misfires, took my 06 audi a4 cabriolet to O Rielley's and they said it was in cylinders 2 and 4. Bought new coils and spark plugs. Called the audi dealership to ask about the gap the plugs should have. A tech said it should be 1.2mm which is .0472 inches, which goes against everything I've seen on forums and other sites where they say it should be between .028-0.032 inches. Anyone know which is true?

 

I just went with the .03 gap size for my plugs, and it's running fine. Also had to replace two connects for the ignition coils because the plastic just fell apart
