Had a similar problem with mine back in may, leaking coolent from the right side of the engine as you look at it, turned out to be a plastic junction that three coolent pipes run-to that then connects to the side of theengine there's a rubber sealent ring inside that had gone hard like plastic causing the coolent to leak down the side of the engine cost me £75 with the parts, hopefully they've checked this for you ?
Well went in this morning expressed me views and they reduced the bill by 300 bullets so better than a kick in the teeth I guess!
