Still got issues as we all have here

anyway was scrolling through vwvortex and read about a flashing EMS.
I have had this when flooring it, i've tested alot of stuff but not the coil packs, which votex believes is the issue when EMS flashes about ten times. Is there truth in this and how do i test all my coil packs.
Fault descriptions are muliple cylinder misfire, cylinder 2 misfire and maximum pressure exceeded.
Sry no codes coz i deleted them.
Thanks
