probably the infamous injector ticking or cambelt pulley. Get the pulley checked because these break up - do a search on here for hdi ticking/noise theres plenty

Car been in the garage, took pulley off nothing wrong, appears to be the water pump pulley? which was replaced 5k / 8months ago which had developed play in it, replaced under warranty :-) as not 12 months ago.
