looks like timing chain tentioner has failed,the chain jumps a tooth (s) and the result is a broken camshaft carrier,and as the camshaft carrier and head have to be a matched pair they have fitted a new head and carrier.the tententioner should have been replaced quite a while ago 130,000 is far to long to have a tentioner fitted...,for future reverence.. ,concencus is replace tentioner at 50,000...60,000 miles,very expensive lesson.also make sure you are using correct oil and genuine filters,as tentioner uses spring and oil to tention chain,
think if im right there was a slight modification on the tentioners,on the early mk6,cant see you being able to claim any thing back thou
