fuel miss fire

[mycaddy]

Hi All,

I have a 06 GTI DSG - running fine until a few weeks ago when I could feel a slight miss, checked at the garage and fault came up with 4th cylinder miss so advise it was the coil pack changed this problem even worse, I was advised that the injector had to be changed so we change and fitted a new one then I was told that the problem still persisted and we had to take of the head due to low compression on the fourth cyclinder any idea's has this looks like this is going to cost£££!!

It could just be the carbon build up on the inlet valves do to cyc 3 and 4, this is due to the crankcase vent thingy venting close to those two cylinders.
Inlet manifold off and clean up, or you u wanna try a terraclean, but the intake clean, not the fuel system one.

Hope that helps
