You have a coil pack down mate, but you need to find out which one, either by process of elimination or using vagcom, if its only 1, then it will cost you about £20 in the dealers

How do i find out which one it is without the means of vagcom and how do i replace the coil packs and how do they look like?

with the engine running disconnect the wiring plugs one at a time 3 will make the engine run worse 1 will leave it running the same then bobs your uncle

They are on top of you engine and go on to you spark plugs.
