Hi I have a seat Ibiza 1.9 TDI and it kept making a ratteling noise and brought it to a seat/VW/Audi specialist and they couldn't find anything, it started to get worse and then I found this part was loose and kept hitting the metal. I put a doing there (don't laugh haha) to stop the ratteling but the screw that kept it there has worn away and loctite and gorilla glue still allows movement so it still rattles slightly. Just want to know what it's called before I ask to get it looked at
