Guys, any thoughts / help would be appreciated.
Audi S3 8V 2015
95k miles
Stage 1

Car developed a misfire (cylinder 2) so changed the following, now getting multiple misfires across all cylinders.

Spark plugs - NGK R8
Coil packs - Genuine VW
Camshaft Magnets - Febi
PCV Valve - Genuine VW

Is there something I'm missing ?
