The I30 has been fixed and was collected on the 4th, the cause of my problems were what they called a kind of "blow hole" a fault in the casting causing coolant to leak into two of the cylinders
I must say though my confidence in keeping the car has been knocked a little I cant help but think what if this happens again outside of warranty having to take the brunt of that cost but things happen and I was very unlucky/lucky depending how you look at it as in lucky the quick turn around and warranty cover but unlucky in the fact things like this must be unheard of with the I30? and probably will not happen again.
