2014 TDCI engine Rattle OSF at ticker-over

[Agriv8]

Hi all I have an Engine rattle Of side Front on my 2014 plate just over 112,000 miles at tick-over

Its sounds to be coming from Power steering pump / Water pump which piggly back of the same drive fully I wandered how the two were coupled and if this could be source of the rattle ( likely to get a far old bashing with road salt and water ! )

Any pointers for other rattle issues in the vicinity - I was dow there doing the Turbo pipe but rechecked my work and nothing seems to be making contact

Due in to trusted garage for some new Break pads ( spotted getting low after putting summer tyres back on ) so will ask them to have listen while 'On The ramps'

Thanks in advance Agriv8
