looks like i maybe going down this road, on friday changed the coilpacks and ignition switch car drove perfect for half an hour and all of sudden misfiring and juddering bigtime! i had to drive the car home and i think thats whats caused more damage! i tried new NGK plat plugs to elimiate the old DEnso iridiums but the car wouldnt even start with either plugs! with the symptoms the cars showing ill be doing a compression check to see if any of the rods or piston are shot. if they are its definetely going to be a full rebuild but a very slow one! im exploring all possibilities at this stage and id like to know what options are available with the 1.8T AEB block. A BIG THANK YOU TO YOU MARK for all your help on Saturday i owe you one mate.
