2010 A4 2.0t cylinder 3 coil pack failure.
 

Any hear of repeatedly failing coil pack on cylinder 3? I've gone through multiple now.

I've had the rear main seal replaced. Pistons replaced on oil consumption test. Now coil packs failing every week.

Never heard of this issue, however a multiple fail would indicate a bigger issue. I would check the spark plug. Something is making the coil pack work extra hard with that cylinder.
