After service including plugs changed number 4 has miss fire when I checked the coil pack rubber insulation has split in half I take it this will cause the miss fire and I need a new coil pack is this the main reason for coil pack failure? (error code came up as p0304 number 4 cylinder miss fire)

Sounds like the coil pack has indeed failed

Get all four changed. Don't buy the mega cheap ones from euro car parts. They fail really quick, the more expensive ones from euro car parts are much better.

2 mins to change them once you figure out how to get the engine cover off.

Ok will change all four I'm keeping this car for the long term what are the best to buy? It will be worth it in the long run. Any recommendations or ones to steer clear of? The rubber insulation that split was inside the coil pack that grips the spark plug white ceramic after only 50k not great

Get the upgraded red top ones from the higher spec Audi engines. Just search Google for red top coil packs mk5 golf GTi. About £90 for a full set.

There you go

Hi thanks to all for your help I swapped number 4 coil pack with number 2 coil pack and cleared the fault before firing up to see if the suspect coil pack was faulty , after scanning for faults again it then showed number 2 cylinder miss fire so found euro car spares having sale on over bank holiday up to 50% off. I got a set of four of the more expensive ones (made by Bougicord) for less than £80 (with free delivery), which was 30% discount to normal price, no need to put discount code in its already priced up with discount.

The offer ends today so have a look if your thinking of buying something you may need soon or in future, it seems they have these sales on at bank holidays so pass the word and look out for it again. You can also sign up for email alerts when they have offers on, might be of use to you one day.

Yeah they are the better ones, I think they stopped selling the cheap ones, one of mine failed within 500 miles.

I have a mint set of the red tops for sale, only did approx 600 miles on them.
