That will be a pulley or idler driven by the auxiliary belt probably. Whatever it is, it sounds near the end of its life.
Yea you should change that every 6-10k miles , how does it drive cause it could be a boost leak causing that will cause whistling so you can check you charge/boost pipes to for tears/hole but that sound to high pitched, can also be an water pump or any other pulley driven by a belt The difficult part is locating the source of the problemThanks I will get it checked
Won't be anything to do with HPFP cam follower will it? As last I changed it, it was badly worn down and they said same would happen again

Then was the fuel pump nipple worn also as if so then possibly the inlet cam also has been rounded.
