FINALLY! Engine sorted. It took them 10 days and I still don't know exactly what the
problem was.
Went to pick the car up, to find a small dent in the boot. Pointed it out to the garage - White Dove, Cardiff - and they apologised and promised to sort it out and give a full valet.
Picked the car up after this to find ANOTHER dent in the door this time. Had the garage send 2 repariers to my house to sort the latest dent out - one for the dent and one to remove the associated scratches.
Car now works, and is dent and scratch free.
Will not be returning to White Dove....
