S4 b6 misfire, help with vag codes

[Velox]

I got a random/multiple cylinder misfire and a cylinder 3 misfire code
Changed cylinder 3's coil and spark plug to cylinder 2 and got a
I got a random/multiple cylinder misfire and a cylinder 2 misfire code
Changed the coil and spark plug to cylinder 1 and got a
I got a random/multiple cylinder misfire and a cylinder 1 misfire code

And why does it it also throw multiple cylinder misfire code when it clearly seems to be 1 bad coil?
can 1 misfiring cylinder cause misfiring in the other cylinders?
