Thanks guys, Just had an mot last month so that was all checked then
in then end also purchased new brake fluid, PAS fluid and new belts aswell from ZMANALEX so hopefully that should be all thats needed for a little while, also thought one of the baffles had gone in my exhaust but on climbing under the car to identify the diff noticed the heat sheild had come loose so now hoping it is that thats causing the vibrating/knocking sound and just requires a washer to fix.
